A simple, scalable way to screen user accounts at the first point of contact.

Fake account sign-ups happen all the time. But most companies don't have a simple way to weed out the good from the bad, and stop would-be fraudsters at the first point of contact.

The Email Hippo ASSESS API uses email address intelligence to perform detailed pre-fraud detection checks during the sign-up process.

We make it easy to spot the warning signs of fraud, and automate preventative action.
