TL;DR — 5 things to know before reading

• Aimfox and LinkedIn Sales Navigator are not direct competitors — Sales Navigator finds prospects; Aimfox automates outreach to them
• Sales Navigator is a search and intelligence tool (advanced filters, lead lists, InMail credits); Aimfox is a connection and messaging automation tool
• Most serious B2B outbound teams use both: Sales Navigator to build the target list, Aimfox to run the campaign
• LinkedIn Sales Navigator InMail limits mean InMail-only outreach caps quickly; connection request campaigns through Aimfox run at a different scale
• Contact data from Quarvio removes the dependency on either tool for finding email addresses, since Sales Navigator provides LinkedIn context but not always verified direct email

Our take

This is one of the more common comparison searches in B2B outbound, and it reflects a genuine source of confusion in the market: people see "LinkedIn prospecting tool" and assume all tools in that category do the same thing. They do not. LinkedIn Sales Navigator and Aimfox operate at different stages of the outreach workflow and solving different problems.

Sales Navigator is a prospecting and intelligence tool. It gives you access to LinkedIn's full database with advanced filters (headcount, seniority, industry, technology used, growth signals), saves lead lists, tracks profile changes, and provides InMail credits for messaging people outside your network. You use it to find who to contact.

Aimfox is an automation tool. Once you know who to contact, Aimfox automates the connection requests, follow-up message sequences, and reply management. It does not help you find prospects. It helps you reach them at scale with a consistent process. You use it to contact who you found.

The correct question is not "which one should I use" — it is "do I need both." For most B2B outbound teams doing more than 50 outreach attempts per week, the answer is yes. This guide explains the distinction clearly and shows how the tools fit together with Instantly, Inframail, and Quarvio into a complete outbound stack.

What each tool actually does

LinkedIn Sales Navigator

Sales Navigator is LinkedIn's premium search product, sold separately from LinkedIn Premium and LinkedIn Recruiter.

Core capabilities:

• Advanced people search with 30+ filters (company size, seniority, function, geography, years in role, recent job changes, company growth signals)
• Saved lead lists that update automatically when tracked contacts change roles or companies
• Account mapping: see all relevant contacts at a single target company
• InMail: send messages to people outside your network (typically 20–50 InMail credits per month depending on plan)
• CRM sync with Salesforce and HubSpot
• Lead recommendations based on saved search criteria
• TeamLink: see if colleagues have first-degree connections to prospects

What it does not do: Sales Navigator does not send automated connection requests, does not run message sequences, and does not provide a shared team inbox for reply management.

Aimfox

Aimfox is a cloud-based LinkedIn automation platform.

Core capabilities:

• Automated connection request campaigns (targeting via LinkedIn search or Sales Navigator exports)
• Follow-up message sequences that trigger automatically after connection acceptance
• Unibox: shared team inbox aggregating all LinkedIn DMs across every connected account
• Dedicated cloud IP per account for better LinkedIn detection separation
• AI message personalisation at the campaign level
• Blacklist management to exclude existing contacts or customers
• Campaign analytics including acceptance rate, reply rate, and sequence conversion

What it does not do: Aimfox does not help you find prospects. It operates on lists you already have, whether sourced from Sales Navigator, Quarvio, or any other list.

How the two tools work together

The combination of Sales Navigator and Aimfox is the standard architecture for LinkedIn-heavy outbound programs. Here is how it works in practice:

Step 1: Build the list in Sales Navigator Use Sales Navigator's advanced filters to define your ICP precisely: VP Sales at 100–500 employee SaaS companies in the US, hired in the last 12 months. Save to a lead list. This might be 200–500 contacts.

Step 2: Import to Aimfox Aimfox integrates with Sales Navigator. Export your lead list or use Aimfox's direct Sales Navigator targeting to build the campaign audience. Aimfox pulls the LinkedIn profiles and queues them for outreach.

Step 3: Run the connection campaign Aimfox sends connection requests at a rate that stays within LinkedIn's official connection limit of approximately 100 per week per account. Follow-up message sequences fire automatically once a connection is accepted.

Step 4: Manage replies in Unibox All incoming LinkedIn messages land in Aimfox's Unibox. The team responds from one shared interface without sharing LinkedIn credentials or switching between accounts.

The email layer: LinkedIn reaches people who accept your connection request. Cold email reaches everyone in the ICP whether or not they are active on LinkedIn. For contact data that includes verified email addresses alongside LinkedIn profiles, Quarvio provides one-time contact packages by ICP criteria. Instantly runs the email sequence in parallel through Inframail inboxes.

When Sales Navigator alone is not enough

Sales Navigator's InMail credits are the built-in outreach mechanism for prospects outside your network. LinkedIn Sales Navigator InMail limits typically run 20–50 per month depending on plan. At a 15% InMail response rate, that produces 3–8 replies per month per seat — a volume that is hard to build a pipeline on.

Connection request campaigns through Aimfox operate at a different scale: 100 connection requests per week means 400 per month. At a 25% acceptance rate that is 100 new connections. At a 15% reply rate on follow-up sequences, that is 15 conversations per month per account — more than five times the InMail ceiling even at a lower response rate.

The practical conclusion: Sales Navigator is the right tool for finding prospects and saving intelligence about them. It is not a high-volume outreach channel. Aimfox is the outreach channel that operates at the volume needed to build consistent pipeline from LinkedIn.

When Sales Navigator is worth the cost on its own

Sales Navigator earns its price independent of Aimfox in two scenarios:

Enterprise sales with account-based targeting: If your deal size is $50k+ per year, the ability to map buying committees, track job changes, and CRM-sync lead intelligence is worth the $99–$149/month per rep. The intelligence layer matters as much as the outreach volume at enterprise deal sizes.

Teams already connected to everything they need: If your Quarvio contact list or other verified data source already has the ICP contacts you need, and your team uses Sales Navigator for intelligence rather than discovery, the investment continues to deliver value as a signal tool.

Community evidence

A verified reviewer on LinkedIn automation tools on G2 noted:

"We use Sales Navigator to build the list and Aimfox to work it. Sales Navigator's search filters are unbeatable for finding the right people. Aimfox is what actually does the outreach. They complement each other — I would not swap one for the other." — Head of Sales Development, B2B SaaS, G2 verified review

Frequently asked questions

Do I need both Aimfox and LinkedIn Sales Navigator?

It depends on your prospecting approach. If you already have a verified contact list from another source (like Quarvio), you may not need Sales Navigator at all — Aimfox can run campaigns from any LinkedIn URL list. If you rely heavily on LinkedIn for prospecting discovery, Sales Navigator's advanced filters are worth the cost. Most high-volume outbound teams eventually use both, but Aimfox is the necessary outreach layer regardless of where the list comes from.

Can Aimfox replace LinkedIn Sales Navigator's InMail?

Not directly. InMail lets you message people outside your network without a connection. Aimfox sends connection requests and messages to accepted connections. The two are different mechanisms. What Aimfox provides is higher volume than InMail allows: 400 connection request attempts per month (at LinkedIn's limit) versus 20–50 InMail credits. For teams trying to reach people at scale, connection-based outreach through Aimfox typically produces more total conversations.

Is LinkedIn Sales Navigator required to use Aimfox?

No. Aimfox can target prospects from standard LinkedIn search without Sales Navigator. However, Aimfox integrates with Sales Navigator and can import lists directly, which makes targeting more precise. You can start with standard LinkedIn and add Sales Navigator later if your targeting needs become more complex.

What happens when someone does not accept a connection request?

Aimfox does not send messages to people who have not accepted the connection request — those messages would go as InMail, which requires Sales Navigator credits. For non-accepters, the email sequence running through Instantly in parallel becomes the primary outreach channel. This is why the combined email-plus-LinkedIn approach produces better overall results than LinkedIn alone.

LinkedIn finds the conversation. You still need the contacts first.

Sales Navigator helps you identify prospects. Aimfox helps you reach them. But neither tool solves the problem of finding verified email addresses for the same people. Quarvio provides verified B2B contact packages by job title, company size, and industry — one-time purchase, no monthly subscription, unused credits returned within 12 months.
