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.

Our mission

We believe that emailsecurity should never get in the way of people doing their jobs. That is why we design email security that is always there, always on, and never a burden. Employees don’t have to make extra choices, recipients don’t have to jump through hoops, and IT departments don’t have to manage complex infrastructures. Security is guaranteed in the background, so email simply works, safely.

Our approach

Unlike solutions that rely on awareness or user actions, SecuMailer is loved precisely because it doesn’t create friction. We remove complexity for employees, minimize overhead for IT, and keep communication smooth for recipients, without compromising on compliance or safety. This combination of usability, security, and simplicity is what defines our vision for the future of digital communication.

Data sovereignty

At SecuMailer, we believe organizations should remain in full control of their own data. Our solution is designed with European data protection standards at its core, ensuring that sensitive information stays within Europe and under your control. This approach means data is never handed over to foreign providers, and compliance with GDPR and national regulations is always guaranteed.

Trusted by many

Today, organizations in highly regulated environments trust SecuMailer to protect sensitive data while keeping work easy. From hospitals safeguarding patient records to municipalities communicating with citizens, SecuMailer enables secure digital communication without the frustration.

Why Choose Secumailer

SecuMailer keeps your data safe, your organization compliant and your users happy without any trade-offs.

Secure email without compromises
Organizations today are required to protect their most valuable asset: sensitive data. The question is no longer whether email should be secured, but how to do so while staying compliant with strict standards such as GDPR, NTA 7516 and eIDAS, without making daily work more complicated. Many solutions make secure email feel like a compromise. They rely on user awareness, placing the responsibility for security on employees who already have other priorities. On top of that, they introduce extra steps, deliver messages through portals, and ask recipients to log in again and again. The result is irritation, and large amounts of sensitive data being stored in places no one really wants.

SecuMailer takes that frustration away.
We shift the responsibility for email security from individual employees to the organization itself. Security is enforced through predefined transport rules, so users can simply send mail as they normally would do. Messages are delivered securely and directly into the recipient’s inbox. Authentication is only requested when required, while meeting the highest security standards. Once a message has been delivered, it is wiped from our servers, just as a postman who delivers a letter no longer holds on to it. This reduces exposure and supports true data minimization.

With SecuMailer, organizations achieve compliance without burdening their people. With SecuMailer users experience secure email as easy as ever, recipients get their messages where they expect them, and IT maintains workplaces without unnecessary complexity. The result is what secure email should always have been: simple, compliant, and safe, without compromises.

Why Secumailer
  • What we don’t store can’t be leaked: messages are never kept longer than needed.
  • Call, email or log a ticket, no barriers, no phone trees, just help when you need it.
  • We meet the highest European standards: ISO 27001, NEN 7510, eIDAS, ECSO and ISAE 3000 SOC Type II.
  • Rated 9.2 by our users because secure email shouldn’t be frustrating.
