Sign-up form widget

Stop fake and mistyped emails at the door.

Add one script tag to your website. Every email field is checked as people type: typos get a suggestion, and invalid or disposable addresses are blocked before the form is sent.

FAQ

Questions, answered.

The short version of how Confirmail works.

The form keeps working normally: the widget fails open and never blocks a real visitor because of an outage, a limit or an empty balance.

Your next campaign deserves real inboxes.
