MailSift

About

MailSift enables developers to prevent invalid, disposable, relay, typo, role based, and risky emails from reaching a product or campaign. A single API reply delivers over fifteen checks and a trust score from zero to one hundred in under 100 milliseconds. You can verify individual addresses, handle CSV lists, or connect via the API. Begin with 500 complimentary verifications, and purchased credits do not have an expiration date.
