Acceptable use: what you can and cannot send through MailProof

MailProof is a formal, on-the-record service, and its terms set out what you may send. Staying within them keeps your account in good standing and your certificates meaningful.

What it's for: legitimate business and personal communications where proof of delivery matters — contracts, notices, compliance communications, property notices and similar correspondence.

What is not allowed: you must not use MailProof to send spam, or content that is fraudulent, threatening or defamatory. As the account holder you are responsible for the legality of what you send, and for having the right to send it to the recipient.

A few practical points:

• Send from your own verified address. MailProof requires a valid business or organisation email; free-provider addresses are not accepted, and the certified email goes out under your real address.
• The service is provided as is. A certificate is strong evidence of delivery, but MailProof does not warrant outcomes in any legal proceedings, and you should not rely on it as legal advice.
• Your content is your own. Message content is only ever accessible to you as the account holder, and is not shared with third parties except where the law requires.

If you are ever unsure whether a particular use is appropriate, err on the side of caution — the value of a MailProof certificate rests on the service being used properly.
