Email Validation and Verification REST API v1 - How To

The Email Validation and Verification API is a simple API that can be used to validate and verify a given email address. This API will check the email address's syntax, look for the domain's MX records, perform an SMTP check, check whether the address is part of a catch-all mailbox, and more. In the event that a potential typo is detected, the API can offer a did-you-mean suggestion. Use of this API requires a paid plan, starting at $25.
