We've been working on Bounso for the past few months, and we're excited to share it with you today.
Bounso is B2B email verification that actually verifies catch-all domains. We recover the 40% of leads that every other tool marks as "Unknown."
Why we built this?
We kept seeing the same problem when running cold email campaigns: 40% of B2B emails are catch-all domains. Gmail, Hotmail, custom domains at small companies — they all accept mail to any address without rejecting invalid ones.
Most email verifiers just give up. They mark these emails as "Unknown" or "Risky" and you have two choices:
Send blind and tank your sender reputation
Throw away 40% of your list
Neither works. You lose money either way.
What Bounso does?
With Bounso, you get:
Verifies catch-all domains individually: We check if the specific mailbox exists on catch-all servers using SMTP validation, MX checks, and domain signals. You get a real answer, not "Unknown."
99.2% accuracy: Real-time verification against mail providers, known spam traps, and disposable email services.
Real-time API: Verify single emails instantly or batch-verify thousands in seconds.
Bulk CSV uploads: Drop your list, get results. No API coding required.
One-click export: Download verified lists ready for your CRM or cold email tool.
Catch-all detection: See exactly which emails are catch-all (so you know what you're getting).
Usage-based pricing: Pay only for what you verify. No monthly seats, no surprises.
