Hey Product Hunt 👋
I'm Waqas, founder of Bounso.
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.
