Email Pie is a wonderful little JSON API that gives you a simple way to validate email addresses. We'll let you know if that email address is legit or not.
Well, first we make sure the email is formatted correctly. Catching things like invalid characters or no @ signs. Then, we make sure that the domain is configured to collect email. Finally, we check for common misspellings.
|[email protected]@for.sure||invalid formatting||json|
|[email protected]||mispelled gmail||json|
|[email protected]||bogus domain||json|
