Numerous partners in Switzerland and abroad have already integrated IncaMail into their applications or can help you connect successfully.

The name “INCA” is based on the four security features of IncaMail:

Integrity (change protection)

Swiss Post ensures that your e-mails remain complete and unchanged while being sent via the Internet.

Non-repudiability

IncaMail detects the sending and receipt of your e-mails. For the “Registered” dispatch type, you will receive as proof a digitally signed receipt with a time stamp.

Confidentiality (access protection)

IncaMail encrypts your e-mails according to a patented process. The process guarantees that third parties will not be able to view or falsify your data during sending.

Authentication (protection against falsification)

IncaMail checks senders and recipients of encrypted e-mails and assigns them a trust level of up to three stars. As a minimum, the e-mail address must be verified.

  • You send your e-mail with all attachments via web interface, e-mail client or business software encrypted to your recipient. You can choose between the dispatch types “confidential”, “personal” or “registered”.
  • After clicking on “Send”, your e-mail will be transmitted to the IncaMail server via a secure connection.
  • If your recipient has integrated IncaMail into his e-mail client or business software, he will receive your e-mail directly via a secure connection.
  • If your recipient uses an e-mail service without IncaMail integration (e.g. Gmail, GMX), the system automatically converts your e-mail into an encrypted attachment. The encrypted attachment is delivered to your recipient by default message in his mailbox. He opens the attachment by entering his IncaMail password directly in his mailbox.
  • If your recipient is not yet registered on IncaMail, he opens the encrypted attachment with a security code sent by IncaMail (“confidential” dispatch type). If you select the “personal” dispatch type, your recipient will be asked to register on IncaMail. He then opens the attachment via his personal IncaMail password.
  • As a sender of confidential and personal IncaMail messages, you will receive a dispatch confirmation. With IncaMail registered mail, you will receive a receipt of dispatch and delivery in the form of a signed PDF file.
  • A: The digital signature proves that the e-mail comes from Swiss Post.
  • B: The sender address indicates the original sender and indicates that the e-mail was delivered with IncaMail.
  • C: The subject line indicates that the e-mail has been protected by IncaMail.
  • D: The sender is indicated by his e-mail address and - if specified - by his postal address.
  • E: The trust level confirms the sender's identification level with IncaMail. As a minimum, the verification of the e-mail address is required. In total, three stars can be achieved.
  • F: The message ID is used to track individual e-mails and assign them if necessary.
  • G: The attachment contains the entire e-mail in encrypted form (SMIME). Clicking on the attachment opens a secure website in the browser. The username and password can be entered there, after which the encrypted attachment opens. If the recipient does not wish to register on IncaMail, he can alternatively have a security code sent to his e-mail address. By entering this code he can open the encrypted attachment.

Please pay attention to these characteristics when receiving an IncaMail message in order not to fall victim to any phishing attempts!
