Use Hunter.io To Verify Emails

Hunter.io is a leader in the email verification space, and when you pair their Email Verifier API with Gigasheet’s no-code functionality, you can verify massive address lists - from a few hundred to millions of rows of data. The Email Verifier API requires an email address as an input and returns the result of the verification, indicating whether an email address is deliverable or not. Additionally, it includes optional detailed validations as well as a confidence score.
