REST API

Developer portal ›

SecuMailer has a REST API for sending secure emails. Both the GDPR and the NTA 7516 functionality are fully accessible via this API.

The API is documented with OpenAPI specification 3.0.1.

The REST API has webhook functionality, which means that the SecuMailer platform can communicate email events with an HTTPS endpoint of the sender.

SMTP API

The SMTP API is usually the simplest integration option for many backend applications because backend applications often have a provision for an SMTP client on board.

We have successfully integrated for customers with Salesforce, SAP and Centric. We have also successfully integrated with patient file systems such as Medisoft Dossier Manager.

GraphQL API

The SecuMailer platform offers insight into email events. This can be done on the basis of a (push) webhook call (see REST API above) and on the basis of a (pull) GraphQL endpoint.

What is Private Dutch Cloud?

SecuMailer is built with security by default in mind. This means that every step in the transport of email is safeguarded. Normally, email traffic flows through SecuMailer’s secure European platform.

With Private Dutch Cloud, your organization can take this one step further: the entire transport process of emails runs via our own Dutch cloud environment. All processing and data handling is done in The Netherlands. Messages are routed through our managed private cloud environment, securely encrypted, and delivered directly to the recipient. This ensures that sensitive email traffic always remains under your own control.

Why is Private Dutch Cloud important?

By routing email transport entirely through our Dutch cloud environment, you keep full control over how and where data flows.
Private Dutch Cloud is especially relevant for organizations with strict requirements on data transport and sovereignty. It supports:

Internal data sovereignty and continuity policies

Confidentiality and compliance obligations

Protection against risks linked to non-European cloud providers

Why choose Private Dutch Cloud?

Dutch sovereignty and European guarantees

With Private Dutch Cloud, we provide a fully Dutch and therefore European alternative without dependency on US hyperscalers or non-EU investors. We meet the requirements of the European Economic Area (EEA) and proudly carry the ECSO Label of Trustworthiness.

What once seemed like a theoretical risk has become reality through recent geopolitical incidents. With Private Dutch Cloud, organizations can safeguard their digital continuity themselves.
— Yvonne Hoogendoorn, CEO SecuMailer
