Send emails with legally verifiable proof of delivery. Every message gets a timestamped PDF certificate — admissible in disputes, compliance audits, and legal proceedings.
* 10 free certified emails every month • Prices include UK VAT • No account needed to verify
MailProof routes your emails through a certified relay that records the full SMTP delivery chain. You get a timestamped PDF certificate proving your message reached the recipient's mail server — sent from your own email address, with your own branding. No special software, no plugins, no configuration.
Every confirmed delivery generates a formal PDF certificate with unique certificate ID, tracking code, full timestamped delivery timeline, and attachment manifest. Admissible as evidence in legal proceedings.
Recipients see your real email address, not ours. Full brand consistency for professional communications. No generic relay addresses — just you.
Follow your email through every stage: submitted, dispatched, delivered, confirmed, and opened. Know exactly when your recipient reads your message with full timestamps.
Attach contracts, invoices, notices, or any document up to 10MB. Attachment filenames are recorded on the delivery certificate as evidence of exactly what was sent.
All data protected by TLS 1.3 in transit and AES-256-GCM encryption at rest. Message content is only accessible to the account holder. Military-grade security throughout.
Recipients can independently verify delivery at mailproof.co.uk — no account required. Just enter the tracking code or certificate ID for instant, independent verification.
