FoxyTrace, email with proof
A French service that seals an email and its attachments, records the recipient's response, and produces a publicly verifiable certificate.
Field notes
The service builds a certificate around an email exchange rather than relying on screenshots or read receipts. Its example shows an Ed25519 signature, an RFC 3161 timestamp, and a chained proof hash, while the page says the recipient must confirm access to the address before reading. The listed price is €2 per send, with the first send free; a company plan is described as forthcoming. The site explicitly distinguishes its technical certificate from qualified eIDAS delivery and civil identity verification.
