Overview

What the Email Verification API does

Bounced invitations and disposable addresses quietly break onboarding. The Email Verification API checks that an address can receive mail, whether it is throwaway or a generic role address, and returns a risk score, so forms can correct mistakes on the spot and risky sign-ups can be reviewed.

It is a silent check: nothing is sent to the address.
