About Quarvio
Built by cold-email practitioners who got tired of paying twice for unverified data.
Every cold-email campaign starts the same way: buy a list, load it into your sending tool, watch a third bounce. Then pay again to re-verify the bounces. Then wonder why the cost-per-reply is so much higher than the vendors implied.
Quarvio exists to close that gap. One credit, one verified contact that arrives in your inbox ready to send. No bounced addresses padded into the count. No re-verification surcharge. No monthly subscription ticking whether you use it or not.
If your filters yield fewer verified contacts than you ordered, unused credits come straight back to your balance. That's not a policy exception — it's how the system is built.
What we are
- A B2B data tool, not a sales platform
- Pay-per-contact, not a subscription
- Global coverage — every industry, every country
- Verification included in every order, always — no upsell tier for clean data
- Manual fulfillment so quality never gets automated away
What we are not
- A CRM, a sequencer, or a dialler
- A volume reseller — we don't dump raw unverified exports and call it a list
- A subscription trap — credits are yours for 12 months, no monthly burn
