mailverify, address checking in real time

Real-time email verification that checks each address against live mail servers, flags disposable and catch-all domains, and returns a confidence score.

The mailverify site, headed "Verify email addresses in real time", beside a card showing a verification result.

An address list goes stale quietly. The bounce rate is how most people find out, which is after the send rather than before it.

What it does

mailverify checks each address at the moment it is asked, flags disposable and catch-all domains, and returns a confidence score rather than a bare valid or invalid.

How it’s built

Checks run against live mail servers at request time rather than against a stored list, so an address that stopped working yesterday is caught today.
