What people use MailProof for

MailProof is used wherever proof of delivery matters. Common uses include:

• Contracts and agreements — proof the other party actually received them
• Deadline-sensitive notices — terminations, cancellations and warnings delivered on time, with evidence they landed
• Regulatory compliance — GDPR notifications, financial disclosures and other documented communications
• Landlord and tenant — rent-increase notices, and maintenance or eviction warnings

In each case the value is the same: instead of relying on the other party to confirm receipt, you hold an independent, timestamped certificate that the message reached their mail server.
