FAQ's
Communicating securely should be just as simple as a regular email. At SecuMailer, we often receive questions about our encryption, privacy legislation such as the GDPR, and integrations with Microsoft 365, whether you are an IT administrator looking for SPF and DKIM or a healthcare professional with questions about NEN 7510. If your question is not listed, our team is happy to help.
Frequently Asked Questions
Encryption
TLS secures the connection between mail servers. With end-to-end encryption, the message itself is encrypted and stored securely, so only the recipient can read it. S/MIME is a form of end-to-end encryption that requires certificates, which is often more complicated for users.
With SecuMailer, you can easily secure emails from within your email application. All emails are automatically secured; you don't have to do anything yourself.
Very secure. The content of the email is in a secure environment and the recipient needs an extra code to open the message.
The keys are securely managed within the SecuMailer environment.
Authentication & Integrity
These are checks that prevent someone from sending emails in your name (spoofing protection).
SecuMailer works together with these checks so that mail servers can verify that the sender is correct.
By properly setting up SPF, DKIM, and DMARC and using secure mail solutions like SecuMailer.
Storage & Data
Yes. Messages sent via SecuMailer are stored encrypted during transmission. After delivery, the messages are no longer present on our platform. Compare it to a digital mailman; he doesn't keep copies of the letters he delivers.
SecuMailer works with servers within the European Union, so data falls under European privacy regulations.
Messages are never stored by us, only the sending logs (metadata).
Privacy & Legislation (GDPR)
If you send personal data, you must use appropriate security. SecuMailer helps organizations comply with this.
When sending personal information such as name, address, or phone number, and confidential information such as medical or financial data.
No, a standard TLS security offers no guarantees for the actual encryption of data. With standard TLS, the priority to deliver is higher than to secure. That is why many organizations choose a solution like SecuMailer where that guarantee can be given.
SecuMailer provides a data processing agreement (DPA) stating how we handle personal data.
Assess the incident and possibly report it to the Data Protection Authority. Secure mailing reduces this risk.
SecuMailer is widely used in healthcare and supports organizations in complying with this standard. SecuMailer is NEN 7510 certified.
Yes, the security and control mechanisms align with government requirements.
Yes. Many legal organizations use secure mailing to protect confidential communication.
Security
When sending, you can set up an extra verification. The recipient will then receive, for example, an SMS code to open the message.
Data Retention
In our management portal, organizations can manage their own settings. This also shows which data is present, and data can be mutated or deleted.
Ease of Use & Adoption
100% because the sender doesn't make a choice about whether or not to use it. Everything is set up in the background and the user doesn't notice anything.
No, the recipient receives the message directly in their own inbox...
No problem, SecuMailer takes care of the security and delivers to the recipient's inbox.
The recipient receives the secured message in the inbox of the mail application on the mobile device.
Yes. SecuMailer integrates with Outlook and Gmail. SecuMailer can work with any conceivable mail server.

SecuMailer is connected via a mail relay that is fully under the customer's control; that connection can be switched off within a minute. Specific email addresses can be excluded from SecuMailer, so even in a hypothetical scenario where we are unavailable, email traffic remains possible.
Implementation & Management (for organizations)
SecuMailer can easily be linked to Microsoft 365.
Yes. Organizations can set rules so that emails are automatically secured.
SecuMailer can easily grow with organizations, from small teams to large organizations.

Risks & Threats
Always check the email address and use secure mailing for confidential information.

Watch out for unknown senders, strange links, and unexpected requests.
That sensitive information reaches the wrong person.
