# Free Email Verifier

Free email verifier: check up to three addresses for deliverability and see valid, risky, invalid or unknown, with the catch-all flag and the mail server.

Interactive version: https://www.routergrowth.com/free-gtm-tools/email-verifier

## How it works

1. Ask the mail server: Each address goes through a verifier waterfall: the cheapest first, the next one when a server does not answer. (`contact.verify`)
2. The result page carries a prompt that runs the same calls at volume from your own agent, priced per call.

Inputs: Emails (e.g. jane@acme.com)

## 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.
