You can also follow the QR code and you will be informed of the status of the message via a web confirmation app.

Simply. Seal. Emails.
Vereign SEAL vs. Registered Mail

“The actual probative value of registered mail is shockingly low.”

Dr. Felix Greve, lawyer, IT security expert and co-founder of Vereign
Vereign SEAL

With the use of Vereign SEAL, the sender pursues the purpose of being able to prove beyond doubt that the recipient actually received the contents of a specific message.

Registered mail

Registered mail, however, does not deliver this by a long shot. The track record of such mail, which extends across several decades, proves this structural inability.

Comparison of Vereign SEAL and conventional registered mail
Vereign SEAL What is proven? Registered mail
Objectively secured proof that the email text and attachments actually originate from the specified email account and have not been falsified. Sender address/identity Is not verified. There is no guarantee that the sent envelope actually originates from the sender.
The content of the email and all attachments is unchanged and can be verified using Vereign SEAL. Document content Is not checked by the post office. Registered mail only refers to the envelope, which could also be empty.

The only sensible option up to this point: ask independent witnesses to be present, while the contents are being placed in the envelope.
The blockchain-hardened metadata prove that the message content was sent at a specific point in time. Confirmation of dispatch Printed and machine-generated receipt for postage of an envelope with unknown content.
Technical metadata and the transport route to the mail server are blockchain-hardened. Receipt At best, the receipt of the envelope (with unknown content) can be proven by the postman´s testimony.

However, after hundreds, if not thousands of deliveries, the postman must still be certain of a specific delivery – and be ready to testify in court.
VEREIGN SEAL also offers the option of voluntary confirmation on the part of the recipient.

Here, the recipient’s confirmation does not only refer to the envelope; the receipt of the specific message content (email, cover letter and attachments) is also conclusively confirmed.
Special case:
registered letter with acknowledgement of receipt
When registered with a reply slip, the recipient voluntarily confirms receipt with handwritten signature.

But even if the recipient is polite enough to obey the request, the sender will at most receive a confirmation that an envelope has been delivered. Once again, the contents of this envelope remains completely unclear.
Your email and attachments will be archived in an encrypted and tamper-proof distributed file system accessible by the participants of the message only.

The original email (inclusive its attachments) can be easily retrieved by clicking or scanning your QR Code SEAL.
Bonus:
Revision-proof archive
Neither the receipt for postage nor the reply slip of the recipient prove that the content of the letter has been archived in an unmodified form.
