About

Abstract's email validation API checks whether an email address is deliverable, disposable, or a catch-all, which keeps signup and newsletter bots working with clean lists. The free plan needs no card and includes 100 validations a month. It adds verification to a catalog category that is otherwise all sending and forms.
