IncaMail, from Post CH AG, is a secure email service designed to protect sensitive digital correspondence and provide verifiable delivery for official communication. The app sends end-to-end encrypted messages and large attachments, issues digitally signed delivery and acceptance receipts, and uses patented SAFE technology so recipients can open encrypted HTML attachments without extra software. It integrates with Outlook and ERP systems, supports up to 1 GB files, and targets HR, legal teams, government bodies, and private users needing legally recognized secure transmission.

IncaMail serves formal, legally recognized electronic delivery

The app functions as an alternative to registered physical mail, providing verifiable digital transmission for official documents. It combines encrypted message transport with a registered-mail workflow that issues digitally signed delivery and acceptance receipts, and it is recognized by the Federal Department of Justice and Police for official electronic communication in Switzerland. This positions the tool for use in regulated or legal workflows.

How private are your messages with IncaMail?

Security rests on end-to-end encryption and patented SAFE technology that packages encrypted content as HTML attachments for straightforward opening. The app complies with Swiss FADP and EU GDPR, which frames data handling and legal recognition. Recipient access options include secure key links and one-time codes, trading convenient read access for stronger verification of identity when sensitive data is exchanged.

Is IncaMail easy to set up and access for recipients?

Onboarding and access prioritize secure verification for recipients: many messages are readable via a secure key link or by entering a one-time code, avoiding the need for a full account. That access model reduces installation requirements for recipients but produces extra retrieval steps that private users describe as a necessary trade-off when exchanging payslips or other sensitive documents.

Does IncaMail work across devices and enterprise systems?

The app runs on iPhone and iPad, Android, and modern web browsers, and it offers Outlook plugins plus REST, SOAP, and SMTP APIs for deeper system integration. That platform coverage lets organizations embed secure delivery into existing workflows and send larger files up to 1 GB without separate transfer tools. Administrators can connect the service to SAP and other ERP systems for automated secure correspondence.

Suitable for regulated workflows that accept verification trade-offs

IncaMail is a pragmatic choice for organisations and professionals who require verifiable, legally anchored transmission rather than casual immediacy. Expect operational trade-offs around recipient convenience, which should be planned into communication policies and onboarding. For teams that prioritise auditability and legal proof of delivery, the app fits workflows that tolerate extra verification in exchange for stronger legal assurance.
