How to use Quarvio and Aimfox together 2026: LinkedIn campaigns with verified contact data

Last updated: June 2026 · James Whitfield, Lead gen agency owner, 50+ campaigns/month

---

TL;DR — 7 things to know before reading

• Quarvio delivers verified B2B contact lists as a CSV; each contact record includes a LinkedIn profile URL that imports directly into Aimfox for connection campaigns
• One Quarvio order feeds two outreach channels simultaneously: LinkedIn via Aimfox (using the LinkedIn URL column) and email via Instantly (using the email address column)
• The exact import steps in Aimfox: upload CSV → map LinkedIn URL field → map first name → confirm import → create campaign → launch
• Quarvio credits are one-time purchase, valid for 12 months — one order can fuel multiple sequenced campaigns rather than being consumed in a single large import
• Five workflow frameworks exist for different operational setups: solo operator, agency client onboarding, multichannel coordinated, credit optimisation, and segmented multi-campaign
• Troubleshooting the import step — LinkedIn URL column mapping, first name fallbacks, and failed send rate diagnosis — is the most common friction point in the Quarvio-to-Aimfox workflow
• Verdict: the Quarvio — Aimfox workflow eliminates the sourcing-to-outreach gap; verified data means fewer failed connection requests to inactive or non-existent profiles, and the same data immediately powers parallel email outreach without a second sourcing step

Our take

Running 50+ outbound campaigns per month, the biggest operational drag I see across teams is the contact sourcing step. Teams spend hours building lists in LinkedIn Sales Navigator, exporting them, cleaning them, uploading them to email tools, then separately sourcing email addresses for the same prospects. The result: two parallel sourcing operations for two channels, neither of which is fully verified.

Quarvio solves this by delivering a single verified CSV with both LinkedIn profile URLs and email addresses per contact. One order, one sourcing step, two channels. Aimfox gets the LinkedIn profile URLs for connection campaigns; Instantly gets the email addresses for email sequences via Inframail inboxes. This guide covers the exact steps from Quarvio CSV to running Aimfox LinkedIn campaign, plus five workflow frameworks for different operational contexts.

What Quarvio delivers

Quarvio provides verified B2B contact lists filtered by:

• Job title (e.g., VP of Sales, Head of Marketing, Engineering Manager, CTO)
• Industry (e.g., SaaS, healthcare, financial services, logistics)
• Company headcount (e.g., 50–200, 200–1,000, 1,000+)
• Geography (e.g., United States, United Kingdom, DACH region, APAC)

Each contact record includes: first name, last name, verified business email, company name, job title, and LinkedIn profile URL (where available for that contact's industry and region).

Credits: one-time purchase, valid for 12 months. No monthly subscription. Unused credits roll over within the validity period.

Quarvio pricing:

• 5,000 credits: $129
• 10,000 credits: $199
• 25,000 credits: $399
• 50,000 credits: $699

Step 1: Specify your contact criteria on Quarvio

Before ordering, define exactly who you need. The more specific the criteria, the tighter the audience-to-message fit in Aimfox.

Criteria decisions:

• Job title: Align with your ICP. "Head of Marketing" for a marketing technology tool. "VP of Engineering" or "Engineering Manager" for developer-focused tools. Avoid broad categories like "Marketing Professional" that mix many seniority levels.
• Industry: Narrow to the 1–3 verticals where your solution fits best. Broader industry filters produce larger lists with lower per-contact relevance.
• Company size: Match to your deal size. SMB outreach targets 10–200 employee companies; mid-market targets 200–1,000; enterprise targets 1,000+.
• Geography: Match to your sales coverage. For European audiences, specify country or region rather than "Europe" for better targeting precision.

Submit these criteria via the Quarvio order process. The resulting CSV is delivered to your email or downloadable from your Quarvio dashboard within the stated delivery window.

Step 2: Review and segment your Quarvio CSV

After downloading the CSV, open it in Excel or Google Sheets and perform four checks before any import:

Check 1: LinkedIn URL column population rate Filter to rows where the LinkedIn URL column is populated. Not every contact will have a LinkedIn URL; population rates vary by job function, geography, and industry. Technology sectors and professional services typically have 75–90% LinkedIn URL availability. Traditional industries may be lower. The populated subset goes to Aimfox; the full list (including contacts without LinkedIn URLs) goes to Instantly for email outreach.

Check 2: First name column completeness Aimfox uses first name for personalisation variables. Confirm the first name column is populated for all contacts you plan to import. Configure a fallback in Aimfox settings if any rows have blank first names.

Check 3: Audience consistency If your Quarvio order included multiple job titles or industries, segment into separate CSV files before importing. Each Aimfox campaign should target a single homogeneous audience segment so the message can be written to speak to one specific role type.

Check 4: File naming Name each CSV file with the audience and intended channel: quarvio-vp-sales-us-linkedin.csv for the Aimfox subset, quarvio-vp-sales-us-email.csv for the Instantly subset. Clear naming prevents import errors and makes campaign attribution auditable.

Step 3: Prepare the LinkedIn subset for Aimfox

Create a filtered copy of the CSV containing only rows where the LinkedIn URL column is not empty. Keep these columns in the filtered CSV:

Remove other columns not needed for Aimfox. A clean, minimal file reduces the risk of field mapping errors during import.

Step 4: Import the CSV into Aimfox

1. Log in to Aimfox
2. Navigate to Audiences → Import CSV (or Campaigns → New Campaign → Add Audience → CSV Import)
3. Click Upload CSV and select the filtered LinkedIn subset file
4. In the field mapping screen, map:
   • Your LinkedIn URL column → LinkedIn Profile URL (critical field; Aimfox cannot send without this)
   • Your First Name column → First Name
   • Your Company column → Company (if present)
   • Your Job Title column → Job Title (if present)
5. Review the mapping preview — verify a sample row shows the correct data in each field
6. Click Import

Aimfox processes CSV imports within 1–5 minutes for lists under 1,000 contacts. After import, the audience appears in your Audiences list with a contact count.

If some contacts show errors after import: Aimfox flags LinkedIn URLs that it cannot resolve (inactive or private profiles). These are contacts whose LinkedIn URLs have changed or whose profiles are no longer accessible. Remove them from the audience before launching the campaign.

Step 5: Create and configure the Aimfox campaign

With the audience imported:

1. Navigate to Campaigns → New Campaign
2. Select the imported Quarvio audience
3. Campaign type: Connection Request with Sequence
4. Enable AI personalisation for the connection request. Since you know the exact job title and industry of this audience (from the Quarvio filtering), the AI opener has specific profile data to work with.
5. Write the connection request message:
   • Open with the AI personalisation variable
   • Add one context sentence relevant to this specific job title
   • End with a low-commitment ask ("Worth connecting?")
   • Keep under 200 characters total
6. Add follow-up sequence steps (2–3 recommended)
7. Configure safety limits (20–30 connection requests per day for established accounts)
8. Set sending schedule (business hours in the audience's timezone)
9. Configure stopping rules: stop on reply, stop on connection removed, stop after N steps
10. Preview AI-generated messages for 10–15 sample contacts before launching

Test first: Launch to 30–50 contacts from the audience for 7 days before scaling to the full list. Verify acceptance rates are above 25% and no unusual Aimfox flags before expanding.

Step 6: Set up the parallel email channel in Instantly

The same Quarvio CSV (the full file, including contacts without LinkedIn URLs) feeds the email channel:

1. In Instantly, navigate to Campaigns → New Campaign
2. Under leads, import the full Quarvio CSV (not the filtered LinkedIn subset)
3. Map the email column as the recipient address
4. Connect sending inboxes from Inframail (already warmed and DNS-verified)
5. Write email sequence steps — different messaging angle from LinkedIn:
   • LinkedIn messages: short, conversational, curiosity-led
   • Email messages: slightly longer, can include data points or a specific insight
6. Configure email stopping rules (stop on reply)
7. Launch email campaign on Day 2 or 3 (offset from the LinkedIn campaign launch day)

Prospects who receive both LinkedIn and email outreach in the same 2-week window produce higher combined response rates than prospects on either channel alone per Instantly's cold email benchmarks.

Step 7: Coordinate cross-channel replies

The critical operational rule: when a prospect replies on either channel, pause outreach on the other channel immediately.

• LinkedIn replies appear in Aimfox Unibox
• Email replies appear in the Instantly Unibox

Check both inboxes daily. Cross-reference names and companies between the two inboxes. When a prospect who replied positively on LinkedIn is still in an active email sequence, pause or cancel their email sequence steps manually. A prospect who has already agreed to a call and then receives two more cold email follow-ups loses trust in the sender immediately.

Tracking channel attribution

After both channels have run for 4–6 weeks:

Compare channel-level performance to identify where this specific audience segment responds best. Most B2B segments have a channel preference; this data shapes where you invest more heavily in the next campaign cycle.

5 workflow frameworks for different operational setups

These frameworks translate the general Quarvio-to-Aimfox workflow into specific, actionable configurations for different business sizes and campaign objectives.

Framework 1: Solo operator single campaign framework

Who this is for: An individual operator running a single campaign at a time, targeting one specific ICP segment.

Workflow:

1. Order 500–1,000 contacts from Quarvio with a tightly defined ICP (one job title, one industry, one geography)
2. Filter the CSV to LinkedIn-URL-populated rows: typically 375–900 contacts for Aimfox
3. Import the LinkedIn subset to Aimfox; import the full list to Instantly
4. Write one connection request template for the specific job title
5. Write one email sequence (3 steps) for the same audience
6. Launch LinkedIn campaign at 20/day; launch email campaign on Day 2 at 40 emails/day
7. Run for 3–4 weeks; review acceptance rate and reply rate
8. When the audience is 80% contacted, order the next batch from Quarvio and begin the cycle again

Credit management: 500 contacts per campaign at 20/day = 25 working days to complete the campaign. At 4 campaigns per month, a 2,000-contact order runs 2 months. One Quarvio order funds a sustained operation for months without reordering.

What to track: Weekly acceptance rate (LinkedIn) and weekly reply rate (email). If acceptance rate drops below 25%, audit the message. If email reply rate drops below 5%, audit the subject line and email opening line.

Framework 2: Agency client onboarding framework

Who this is for: An agency operator setting up outreach campaigns for a new client, needing to build and launch within a defined onboarding timeline.

Workflow:

1. Client discovery call: define ICP (job title, industry, geography, company size), messaging angle, and campaign goal
2. Order Quarvio contacts matching the defined ICP criteria
3. Upon CSV delivery, run the 4-step CSV review (population rate, first name completeness, audience consistency, file naming)
4. Create a dedicated Aimfox seat for the client's LinkedIn profile; configure safety limits per the profile's age and history
5. Import the LinkedIn subset to Aimfox; import the full list to Instantly with the client's Inframail inboxes connected
6. Write connection request + 2-step follow-up (LinkedIn) and email sequence (3-step) for client approval before launch
7. Launch LinkedIn campaign after client approval; launch email on Day 2
8. Weekly reporting: acceptance rate, reply rate, conversations started, meetings booked

Separation of concerns: Each client has their own Aimfox seat, their own Quarvio contact file, and their own Instantly campaign. Do not share audience files between clients. Name all files with the client identifier: client-alpha-vp-sales-us-linkedin.csv.

Safety settings per client: Configure each client's Aimfox seat individually based on that LinkedIn profile's age and connection count. New client LinkedIn profiles need the warmup ramp protocol; established profiles can launch at standard daily limits.

Framework 3: Multichannel coordinated framework

Who this is for: Teams who want to extract maximum outreach coverage from a single Quarvio order by coordinating LinkedIn and email precisely.

Workflow:

1. Order Quarvio contacts; receive CSV with LinkedIn URLs + email addresses
2. Segment A (LinkedIn+email): contacts with LinkedIn URL — runs on both Aimfox and Instantly
3. Segment B (email only): contacts without LinkedIn URL — runs on Instantly only
4. Aimfox campaign (Segment A): 20/day, business hours
5. Instantly campaign (both segments): 80 emails/day from Inframail inboxes
6. Day 1: Launch Aimfox. Day 2: Launch Instantly
7. Stopping rule enforcement: daily review of both Uniboxes; cross-reference positive replies across channels; manually pause opposing channel sequence on positive reply

Why this maximises coverage: Segment B contacts (no LinkedIn URL) are not wasted — they receive email outreach. Segment A contacts are reached on both channels. Total outreach coverage = 100% of Quarvio contacts, across 1–2 channels per contact depending on LinkedIn URL availability.

Attribution tracking: Tag all Segment A contacts with "linkedin+email" and all Segment B contacts with "email-only" in your CRM or tracking spreadsheet. After 6 weeks, compare meeting book rates between segments to validate the multichannel investment.

Framework 4: Credit optimisation framework

Who this is for: Operators managing Quarvio credit budgets across multiple campaigns, wanting to maximise value across the 12-month validity window.

Core principle: Quarvio credits are per-contact, valid 12 months. Spending all credits in week 1 on a single large import is a common waste: if the first campaign's message underperforms, there are no contacts remaining to test a revised message against.

Credit allocation model:

What Phase 1 validates: Message relevance (acceptance rate above 25%), audience fit (positive reply rate above 8%), and channel balance (LinkedIn vs email performance). If Phase 1 acceptance rate is below 20%, rewrite the connection request and test with Phase 2 credits before scaling to Phase 3.

Framework 5: Segmented multi-campaign framework

Who this is for: Teams whose Quarvio order included multiple job titles or industries and need to run separate, message-matched campaigns for each segment.

When this applies: A Quarvio order for "Head of Marketing + VP of Sales at 100–500 employee SaaS companies" delivers contacts across two distinct job functions that require different connection request messages.

Workflow:

1. After receiving the Quarvio CSV, segment by job title: create separate files for each title group
2. In Aimfox, create one campaign per segment with distinct connection request messages:
   • Campaign A message: references marketing-specific challenge
   • Campaign B message: references sales-specific challenge
3. Set per-campaign daily limits so combined volume stays within the seat's daily ceiling (e.g., 10/day per campaign, 20/day total)
4. Track acceptance rate and reply rate per campaign separately to identify which segment responds better

Why segmentation outperforms blending: A message that speaks abstractly to "go-to-market teams" speaks to marketing and sales simultaneously but to neither specifically. A message written for Head of Marketing that references a marketing-specific challenge produces 5–10 percentage point higher acceptance rates than the blended version.

Common mistakes to avoid

Importing contacts without LinkedIn URLs: Aimfox cannot send a connection request without a LinkedIn profile URL. Always filter to LinkedIn-URL-populated rows before importing. Importing the full list without filtering produces import errors and inflated "failed" rates that obscure the actual audience size.

Using the same message for LinkedIn and email: LinkedIn connection requests are limited to 300 characters and work best as conversational, curiosity-led openers. Email allows longer format, more context, and a structured argument. Copy-pasting between channels produces messages that feel mismatched to the channel format in both directions.

Not segmenting multi-title Quarvio orders before importing: If your Quarvio order contained VP of Marketing and Head of Sales contacts, importing them into a single Aimfox campaign forces you to write a message that speaks to both audiences simultaneously — which means it speaks to neither effectively. Create separate campaigns per audience segment.

Spending all Quarvio credits in a single import: Quarvio credits are valid for 12 months. If you import all contacts at once and the first campaign's message does not achieve target acceptance rates, you have no audience remaining to test an improved message against. Sequence credits across multiple campaigns: test 200 contacts, validate the approach, then run the next 500.

Complete Quarvio-to-Aimfox configuration reference

Quarvio + Aimfox configuration reference

The following tables provide exact specifications for every step of the Quarvio-to-Aimfox workflow. Use this as the reference when setting up a new campaign, onboarding a new client, or diagnosing underperformance.

CSV preparation: required columns by channel

LinkedIn URL population rate by audience type

The proportion of Quarvio contacts with LinkedIn URLs varies by segment. Plan Aimfox campaign sizes accounting for this:

Contacts without LinkedIn URLs are not wasted — they receive email outreach via Instantly. Email address availability is consistently higher than LinkedIn URL availability for the same audience, so the full CSV produces value across both channels.

Aimfox campaign configuration by audience size

Always test with a subset before launching the full audience. A connection message achieving 18% acceptance is better identified at 150 contacts than at 1,000.

Aimfox safety settings for Quarvio-sourced campaigns

Parallel channel settings: Aimfox and Instantly

The 24-hour launch offset prevents the same prospect from receiving a LinkedIn connection request and a cold email on the same day. Simultaneous double-outreach creates the perception of being spam-targeted across channels, which drives complaint signals on both platforms.

Campaign performance benchmarks: Quarvio-sourced audiences

These benchmarks apply to Quarvio-sourced contacts: verified, targeted by job title and industry, not recycled from bulk data aggregators. Generic list benchmarks will be lower.

Troubleshooting: 8 common Quarvio + Aimfox workflow problems

Problem 1: LinkedIn URL column not mapping correctly in Aimfox import

Symptom: After uploading the Quarvio CSV to Aimfox, the LinkedIn Profile URL field in the mapping screen is blank or mapped to the wrong column.

Cause: The CSV column header name does not match what Aimfox expects. Aimfox looks for common variations but does not auto-detect all possible column names.

Fix: In the field mapping screen, manually select the correct column from the dropdown for the LinkedIn Profile URL field. Click the dropdown next to "LinkedIn Profile URL" in the mapping screen and select your CSV column manually. After mapping, verify the preview row shows a full LinkedIn URL (starting with https://www.linkedin.com/in/).

Problem 2: High failed send rate after Aimfox import (above 8%)

Symptom: After launching the Aimfox campaign, the failed send rate shows above 8%.

Cause: LinkedIn URL data in Quarvio's CSV is current at the time of delivery, but some LinkedIn profiles become private, inactive, or deactivated after the data is compiled. A failed send rate of 3–5% is normal; above 8% indicates data age issues for that specific audience segment.

Fix: Pause the campaign. Export the failed contacts from Aimfox. Review the failed LinkedIn URLs manually. If profiles consistently return "Page not found," the data for that audience segment may need refreshing. Route failed contacts to the email channel via Instantly using their verified email addresses.

Problem 3: First name personalisation showing blank for some contacts

Symptom: Some connection request messages are sent with "[First Name]" literally in the message, or with a blank where the first name should appear.

Cause: Some contacts in the Quarvio CSV have a blank or null first name field. Aimfox uses the mapped first name field for personalisation variables; when the field is empty, the variable does not resolve.

Fix: Before importing, filter the CSV and fill any blank first name cells with a fallback value (e.g., "there" for "Hi there,"). In Aimfox settings, also configure a first name fallback in campaign settings. Apply this fix before every campaign launch.

Problem 4: Aimfox campaign pausing unexpectedly during active operation

Symptom: A running Aimfox campaign pauses without you manually pausing it.

Cause: Aimfox pauses campaigns automatically when it detects a LinkedIn session issue (CAPTCHA, login challenge, or session expiry). This is a safety feature.

Fix: Log into LinkedIn directly and complete any verification or CAPTCHA. Then in Aimfox, navigate to Settings → Seats and reconnect the LinkedIn seat. After reconnection, the paused campaign can be manually resumed.

Problem 5: Duplicate contacts receiving messages simultaneously on LinkedIn and email

Symptom: A prospect received a LinkedIn connection request and an email on the same day and responds negatively.

Cause: LinkedIn campaign and email campaign launched on the same day, both reaching the same prospect within hours of each other.

Fix: Offset launch dates: LinkedIn campaign on Day 1, email campaign on Day 2 or Day 3. Configure stopping rules in both platforms so that a reply on either channel pauses the other channel's sequence for that contact.

Problem 6: Aimfox AI personalisation generating off-topic openers

Symptom: The AI personalisation is enabled, but generated messages reference irrelevant or incorrect details about the prospect.

Cause: The LinkedIn profiles in the imported audience have sparse profile data. AI personalisation requires sufficient profile information to generate a specific, relevant opener.

Fix: Review the message preview for 20 sample contacts before launching. If more than 30% of previews are generic or off-topic, write a manual role-specific template as the primary message and disable AI personalisation for this campaign. A manually written message accurate for the specific job title and industry consistently outperforms AI personalisation when audience profiles are sparse.

Problem 7: Quarvio CSV has fewer LinkedIn URLs than expected

Symptom: After filtering the CSV for LinkedIn-URL-populated rows, you have significantly fewer contacts than expected for the Aimfox campaign.

Cause: LinkedIn URL availability varies by job function, geography, and industry. Some segments have lower LinkedIn URL availability rates (40–60% vs. 75–90% for technology roles).

Fix: This is expected behaviour. Route the contacts without LinkedIn URLs to the email channel via Instantly. The total audience is still the full Quarvio order size; they are distributed across channels. If LinkedIn coverage is insufficient, order additional Quarvio contacts targeting a different audience segment with higher expected LinkedIn URL availability.

Problem 8: Cross-channel attribution is unclear

Symptom: Prospects are replying, but you cannot determine whether the LinkedIn message or the email drove the response.

Cause: Without explicit attribution tagging, dual-channel campaigns produce replies that look identical in the CRM.

Fix: Implement a simple attribution log: a shared spreadsheet with columns for prospect name, company, which channel they replied on (LinkedIn or email), and the sequence step that prompted the reply. Update this daily when reviewing both Uniboxes. After 6 weeks, count total replies per channel and meeting book rate per channel to inform future campaign investment decisions.

Advanced tactics: 5 approaches for Quarvio + Aimfox operations

Tactic 1: Use Quarvio credits across multiple campaign cycles, not a single batch

The 12-month validity on Quarvio credits makes them a campaign budget, not a one-time purchase. Treat them like an annual advertising budget: allocate a portion to each quarter's campaigns rather than spending all credits in month 1.

A 10,000-credit order at $199 supports 10 campaigns of 1,000 contacts each, or 20 campaigns of 500 contacts each. Plan the credit allocation at the start of each quarter: identify which ICP segments will be targeted, how many contacts each requires, and which months each campaign will run. Submit Quarvio orders for the next quarter's campaigns at the start of the quarter rather than ordering reactively.

Tactic 2: Use failed send rate as a data quality indicator for audience segment decisions

Every Aimfox campaign produces a failed send rate (contacts where LinkedIn URL could not be resolved). Track this metric per audience segment across campaigns.

If your VP of Sales (US, SaaS, 50–200 employees) segment consistently produces 3–4% failed send rate, this is normal for that segment. If your Head of Operations (EU, logistics, 200–1,000 employees) segment produces 12% failed send rate, LinkedIn URL availability for that segment is lower, and future orders should expect fewer Aimfox-usable contacts per 1,000 credits.

Per-segment failure rate data improves future Quarvio ordering decisions: you know in advance that certain segments require more credits to produce the same number of active Aimfox contacts.

Tactic 3: Create ICP-specific message libraries matched to recurring Quarvio segments

If you run campaigns to the same ICP segments repeatedly, build a message library: a set of tested, performing connection request templates and email sequences for each segment.

The first campaign to a new segment is always a test. By the second or third campaign to the same segment type, you have performance data that allows you to deploy the highest-performing variant immediately, skipping the test phase.

In Aimfox, save high-performing campaign templates. In Instantly, save high-performing email sequences. When a new Quarvio order arrives for a recurring ICP segment, apply the saved template immediately and launch without a test phase delay.

Tactic 4: Coordinate Quarvio reorder timing with Aimfox campaign completion dates

Aimfox campaigns run at 20–25 contacts per day. A 500-contact Aimfox campaign completes in 20–25 working days. Plan your next Quarvio order to arrive 1–2 weeks before the current campaign's completion so there is no gap between campaigns.

When a campaign is 70% complete, initiate the next Quarvio order. The new CSV arrives by the time the current campaign finishes. New audience import and campaign setup can begin immediately, maintaining continuous outreach without gaps.

Tactic 5: Use Quarvio data to pre-qualify Aimfox audiences before importing

Not all contacts in a Quarvio CSV should go into an Aimfox campaign. Before importing, apply a pre-qualification filter based on campaign goals:

• Cross-reference the Quarvio CSV against your CRM and prioritise contacts at companies not yet in pipeline
• Filter company size column to a tighter target range than the original Quarvio order specified
• For event-based campaigns, cross-reference against LinkedIn event attendee lists and prioritise matched contacts

Pre-qualified audiences are smaller but produce higher reply rates and meeting conversion rates because every contact has been confirmed as a genuine fit before the first message is sent.

Community evidence

Aimfox reviews on G2 from practitioners using verified contact data for LinkedIn campaigns consistently report lower "profile not found" error rates and higher acceptance rates compared to campaigns sourced from unfiltered LinkedIn searches, with verified data cited as the factor that produces cleaner audience targeting.

Per Instantly's cold email benchmarks, multichannel outreach (LinkedIn connection + email sequence to the same prospect within a 2-week window) produces 40–60% higher total reply rates than single-channel, with the combined effect strongest when both messages are channel-appropriate rather than identical.

"We run every outbound campaign as LinkedIn + email from the same contact list. One Quarvio order, two channels. Aimfox gets the LinkedIn URLs; Instantly gets the emails. Total pipeline from the combined approach is significantly higher than what we were getting from email alone."

"The CSV import into Aimfox takes five minutes once the filtering step is done. Map the LinkedIn URL column, confirm the fields, launch. The verified data means I'm not sending connection requests to ghost profiles and seeing 30% failed send rates. The acceptance rate reflects actual audience quality, not list contamination."

Our actual stack

Frequently asked questions

Does every Quarvio contact have a LinkedIn profile URL?

No. LinkedIn URL availability varies by job function, geography, and industry. Technology and professional services roles typically have 75–90% LinkedIn URL availability; traditional industries or geographic markets with lower LinkedIn penetration rates have lower availability. Filter the CSV to LinkedIn-URL-populated rows for Aimfox; use the full list (email column) for Instantly email outreach. Contacts without LinkedIn URLs are not wasted — they receive email outreach.

How do I verify that Quarvio's LinkedIn URLs are still active?

Quarvio verifies contact data at the time of delivery. LinkedIn profiles can become private or inactive after the data is compiled. When you import into Aimfox, Aimfox flags connection requests to unavailable profiles as failed sends. A failed send rate above 8% in a campaign may indicate that the LinkedIn URL data needs refreshing for that audience segment. For most B2B audiences this rate is well below 5%.

Can I import contacts to multiple Aimfox campaigns from the same Quarvio CSV?

Yes. One Quarvio CSV can feed multiple Aimfox campaigns targeting different audience segments from the same order. For example, if your order contained VP of Marketing and VP of Sales contacts, create two separate filtered CSVs (one per title) and import each into its own Aimfox campaign with a title-specific message. This produces better acceptance rates than combining both titles in a single campaign with a generic message.

What happens to contacts in the Quarvio CSV without LinkedIn URLs?

Route them to your email channel via Instantly. Import the full Quarvio CSV into Instantly using the email address column as the recipient field. These contacts receive email outreach in parallel with the LinkedIn campaign. The email channel has no dependency on LinkedIn URL availability, so the full list is usable regardless of LinkedIn URL population rate.

How long does a Quarvio order take to deliver?

Delivery times vary by order size and ICP specificity. Check the Quarvio order page for current delivery estimates. After delivery, contacts are usable immediately — the CSV does not require additional verification steps before importing to Aimfox or Instantly.

Can I use Quarvio contacts for both LinkedIn outreach and email outreach simultaneously?

Yes, this is the recommended approach. One Quarvio order delivers both LinkedIn profile URLs and verified email addresses for each contact. Import the LinkedIn URL subset to Aimfox for connection campaigns; import the full list to Instantly for email campaigns. Launch the LinkedIn campaign on Day 1 and the email campaign on Day 2. Monitor both Uniboxes daily to cross-reference replies and pause the opposing channel when a positive reply is received.

What is the best Quarvio credit package for starting out?

The 5,000-credit package ($129) is the recommended starting point. It provides enough contacts for 5–10 test campaigns of 500–1,000 contacts each, which is sufficient to validate message angles and audience segments before scaling. Only upgrade to larger packages (10,000+ credits) after confirming which ICP segments and message frameworks perform best in the initial test campaigns.

How do I handle Quarvio contacts that appear in multiple lists (duplicate contacts)?

This can occur if you place multiple Quarvio orders with overlapping ICP criteria. Before importing to Aimfox, deduplicate by LinkedIn URL column (remove duplicate rows where the LinkedIn URL appears more than once). Sending a connection request to the same person twice from the same LinkedIn profile can damage the relationship and flag the account.

What is the recommended campaign size per Quarvio audience segment?

200–500 contacts for test campaigns; 500–1,000 contacts for scaled campaigns once a message variant is validated. Avoid running audiences of 2,000+ contacts from a single Aimfox campaign unless you have confirmed acceptance rates above 30% with a well-validated message.

Does Aimfox support scheduling campaigns to specific contacts at different times?

Aimfox schedules campaigns based on the per-seat active hours setting, not per-contact timing. All contacts in a campaign receive outreach during the same configured active window. To target contacts in different timezones with timezone-appropriate timing, create separate campaigns per timezone group and configure the sending schedule for each campaign's seat to the appropriate timezone.

What happens if a Quarvio contact's LinkedIn profile URL changes after the data is delivered?

Quarvio delivers contact data including the LinkedIn URL at the time of verification. If a contact changes their LinkedIn URL, the old URL in the Quarvio CSV will return a "profile not found" error in Aimfox. These contacts appear as failed sends. The only resolution is to manually search for the updated LinkedIn URL using the contact's name and company. For most B2B audiences, URL change rates are below 2%.

Can Quarvio provide contacts for geographies outside the US and UK?

Yes. Quarvio provides verified B2B contact data for multiple geographies including DACH, Benelux, Nordics, France, APAC, and others. LinkedIn URL availability rates vary by geography: English-speaking professional markets typically have the highest rates. Specify the target geography when ordering and verify the expected LinkedIn URL population rate for that geography.
