Email Verification Without the Bullshit

40% of emails are "catch-all".

Most tools shrug.

We don’t. We say yes or no — that’s it.

"Catch-All” Means “Don’t Know”

And “don’t know” breaks your campaigns.
Most tools return three results: Valid, Invalid, and Catch-all. That last one? Useless. It leaves you stuck.
