Free Email Verifier

Will this email bounce?

Paste up to three addresses. Each is checked against its mail server: valid, risky (catch-all), invalid, or unknown. Nothing you paste is stored.

Free, no sign-up. Real data from the RouterGrowth API, with a daily allowance per network.

How it works

1 step, one API.

The tool is the RouterGrowth API with a form on top. Your agent makes the same calls with one key, at any volume, at the price shown here.

Ask the mail server

Each address goes through a verifier waterfall: the cheapest first, the next one when a server does not answer.

FAQ

About this tool

What is a catch-all domain?

A domain whose mail server accepts every address, real or not, so no verifier can be sure. Those come back as risky: send to them in small batches and watch the bounces.

Do you store the addresses?

No. The address goes to the verifier and the verdict comes back to your browser; we keep a count of runs for the daily allowance and nothing else.

Is it really free?

Yes, with a daily allowance per network so the tool stays open for everybody. No sign-up, no email. The same input inside 7 days is answered from the stored result. Past the allowance, the same calls run from your own agent with a key, priced per call.
