What is MailProof?

MailProof is a certified email service that gives you legal-grade proof that your important messages were sent and delivered. When you send through MailProof, every email is routed through a certified relay that records the full SMTP handshake with the recipient's mail server — their acceptance and the exact timestamps — and turns that record into a formal PDF certificate.

In short, MailProof gives you independent, timestamped evidence that a message reached the other party's mail server. That matters whenever a contract, notice or deadline could later be disputed.

There is nothing to install — no software, plugins or add-ons. You send from your own business email address, so recipients see you rather than us, and each confirmed message produces a PDF certificate you can keep or share.

MailProof is available on a Free plan (10 certified emails every calendar month) with the complete feature set, so you can try certified delivery at no cost.
