Email verification API that catches fake signups

Visit sniffmail.io ↗Alternativestop 6% of March 2026

What it does

SniffMail verifies email addresses before they enter your system without sending a single email. One API call checks if the mailbox exists, detects disposable/temporary emails, flags full inboxes, and identifies catch-all domains. Built for developers: npm install, one function call, done. 10x cheaper than ZeroBounce and NeverBounce. 500 free verifications on signup, no credit card required.
