MailsGuard was built because email verification is a commodity — and the incumbents charge like it isn't.
Every email verification service works the same way under the hood: check the syntax, look up the MX record, probe the SMTP server, flag disposable domains. It is a well-understood technical problem. The accuracy ceiling is set by what mail servers will tell you — and every major service hits that ceiling the same way.
So why does ZeroBounce charge $15 per 1,000 verifications? Marketing, brand, and the absence of a better option. MailsGuard charges $3. The technology is the same. The results are the same. The price is not.
We built MailsGuard for developers who want a clean API, marketers who want bulk CSV processing, and anyone who is tired of paying a premium for something that should cost a fraction of the price.

Every verification runs a full 7-point check: syntax validation, DNS lookup, MX record verification, SMTP probe, disposable email detection, catch-all domain flagging, and role-based address detection. Results include a 0–100 confidence score and a full checks object so you can make your own decision on borderline cases.
