Secure Messaging

Services

SEPAmail.eu, a STET subsidiary since 2024, offers secure messaging services designed to facilitate automated, digital bank account switching and verification of bank details (IBAN Name Check/Verification of Payee) when issuing credit transfer or direct debit orders (thereby helping to limit the risks of fraud and transaction rejection).

SEPAmail.eu operates a secure messaging scheme based on open-source architecture, standards, and implementation guidelines, enabling flow exchanges between participants under a membership agreement.

Only authorized payment service providers (PSPs) may join the SEPAmail network, maintaining a high level of security and fostering trust among end users.

Data is transmitted digitally through connections between the member networks. Messages are routed via SEPAmail missives using the banking networks (online banking) BIC and QXBAN (SEPAmail routing address) codes, linked to their SPI (SEPAmail Platform Identifier).

All interactions are fully secure and protected by several means of authentication (keys, tokens…), ensuring that no unencrypted data is ever transmitted in SEPAmail envelopes.


Our solutions

With SEPAmail AIGUE-MARINE, SEPAmail.eu provides a service that enables bank account switching for individuals, transferring their account from their former bank to a new one. This service was developed in the wake of French regulation transposing the EU Payment Accounts Directive.

The system is simple, free and fully automated, offering a seamless digital experience for individuals wishing to seamlessly transfer their assets and “account live” to their new bank.

SEPAmail DIAMOND is an IBAN Name Check service that verifies account holder details, particularly before issuing SEPA Credit Transfers (SCT) or SEPA Direct Debits (SDD), in order to reduce the risk of fraud and transaction rejection. This service uniquely positions SEPAmail.eu in the wake of EU Instant Payments Regulation, which requires all PSPs to implement Verification of Payee (VoP) before initiating SCT or Instant Payments by October 2025. The updated version of SEPAmail DIAMOND will meet the requirements of this EU regulation by offering PSPs real-time VoP checks at both the domestic and cross-border levels.
