Are MailProof certificates legally admissible?

A MailProof certificate is designed to provide strong evidence of email delivery that can be used in disputes, legal proceedings and regulatory matters.

What gives the certificate its weight is that it is built from the recorded SMTP handshake with the recipient's mail server — an independent, timestamped record of that server accepting your message — rather than from your own say-so. Each certificate carries a unique certificate ID and tracking code, the sender and recipient details, the subject line, any attachment names, and the full delivery timeline. Anyone can confirm it independently through the public verification page.

A few points worth being clear about:

• MailProof proves that a message was delivered to the recipient's mail server at a particular time. It is evidence of delivery, not evidence of what the recipient chose to do with the message afterwards.
• Whether a court, tribunal or regulator accepts a particular piece of evidence is always a matter for them. MailProof gives you a credible, verifiable record to put forward; it cannot guarantee the outcome of any proceedings.
• If a matter is contentious or high-value, keep the PDF certificate and the confirmation email together, and note the certificate ID somewhere safe.

Used sensibly, a MailProof certificate is exactly the kind of contemporaneous, verifiable record that supports a claim that an email was sent and received on time.
