Signupscore

About

Most email blocking tools rely on a common public list from GitHub. That list includes domains like gov, edu, Apple Hide My Email, Firefox Relay, and uk.com, which means genuine customers are often turned away at registration without your knowledge. SignupScore evaluates each domain individually before blocking it. The service also identifies dynamic DNS addresses, nonsensical emails, misspelled domains such as gmial.com, role based accounts, and repeat visitors using alternate spellings. A free tier offers 250 monthly checks. It includes an API and a dashboard.
