Email Validation and Verification API

Abstract's email validation API uses a variety of increasingly sophisticated and frequently updated techniques to ensure you suppress all invalid or risky emails. These techniques include (but are not limited to): checking for syntax errors and typos in the email address (e.g., john@gnamil.com), doing real time SMTP and MX record checks against the email's domain, performing a sophisticated regular expression (regex) check on the email, and using a variety of other filters backed by machine learning to detect invalid or risky emails.

We can also identify and flag other characteristics of an email, such as whether it's from a free email provider (such as Yahoo or Gmail), whether it's from a disposable email services (such as Yopmail), and whether it's from a 'role' email address (such as team@ or @sales@).

We can also help you identify emails that are from recently registered domains, even if those domains otherwise past other filters. Recently registered domains and emails can signal that the user is fraudulent, spammy, or in some other way needs to be reviewed.
