Email Verification Without the Bullshit

40% of emails are "catch-all".

Your verifier shrugs and punts them to "maybe".

We turn them into Yes or No — that’s it.

Your Verifier’s Catch-All Upgrade

Most tools return three results: Valid, Invalid, and Catch-all. That last one? Useless. It breaks your campaigns.

Keep Your Verifier

It's fine for the easy stuff.
Add TLDR Verify

Run the catch-alls through us and we'll resolve them to Yes or No.
More Usable Emails

More reach. More revenue.

We’ve run millions of emails through this tech — not in a lab, but in live campaigns. The results speak:

● 100M+ emails verified and delivered

● 99.2% inbox rate

● 0.8% bounce rate

No other verification service can show numbers like that.

● Built from 10 years of live outbound campaigns

● Used daily by one of the world’s top B2B outreach companies

● Designed for scale, accuracy, and certainty

We’d rather say no than mislead you with a maybe.
