Becoming a Suomi.fi Messages digital mail operator

What is a digital mail operator?

A digital mail operator provides their digital mail service or viewing application to end users for reading notifications and other messages from authorities in Suomi.fi Messages.

A digital mail operator:

  • provides a service directly to the end user,
  • uses strong identification to verify the user,
  • asks the user for permission to display official messages in its service,
  • displays the user’s Suomi.fi Messages inbox through the Digital and Population Data Services Agency’s APIs, and
  • provides its own user communications, guidance and support.

Please note: these instructions are for digital mail service operators. If your organisation sends messages, is a system supplier or technical integration partner for another organisation, you are not a digital mail operator.

A digital mail operator is strictly an organisation that provides a service to end users under an agreement with the Digital and Population Data Services Agency.

1. Indicate your interest

Contact the Digital and Population Data Services Agency at viestit-kayttoonotot@dvv.fi and indicate your interest to displaying official messages sent in Suomi.fi Messages in your digital mail service.

After you contact us, we will tell you about:

  • connection process,
  • requirements,
  • agreements,
  • testing, and
  • the deployment process.

2. Review the requirements and see if your service meets them

Make sure that your service meets all the requirements for digital mail operators and digital mail services.

Review the material:

In particular, consider the following:

User functionality

  • strong user identification
  • secure display of official messages
  • user access management
  • provision of sufficient information to the user on the service.

Data security and privacy

  • processing of personal data
  • logging and traceability
  • data security management policies
  • preparing for incidents.

Communications, user support and customer service

  • user advice
  • customer guidance in various situations
  • handling of questions on official messages
  • communication of incidents to users.

3. Sign the agreement with the DVV

Digital mail operators must conclude the agreement with the DVV before production use.

The agreement consists of the following documents (to be published later here):

Document

Description

Digital mail operator agreement (main agreement)

Definition of the responsibilities, rights, and duties of the parties.

Appendix: Security appendix

Description of the security arrangements, confidentiality, data protection and other information security matters, covering the life cycle of the digital mail service, the activities of the digital mail operator and the continuity of service production during various disruptions. 

Appendix: Cooperation appendix

Description of the cooperation required of DVV-approved partners that provide a digital mail service.

Appendix: Requirement matrix

Description of the technical, functional and security-related requirements that the digital mail service must meet.

Appendix: Testing, review and approval process

Description of the testing, review and approval processes that are used before the service is approved for production use and to changes during the agreement period. 

Appendix: Service description

Description of the service provider’s approved digital mail service that connects to Suomi.fi Messages, which serves as a user interface for the messaging service for electronic notifications and other communications.

4. Implement and test the integration

When the agreement process is underway, you can begin to implement the integration.

Interfaces

DVV provides APIs for:

  • user access management
  • listing messages
  • relaying information about displaying messages
  • relaying read receipts and acknowledgements.

Testing

DVV may grant access to the test environment and the cooperation channels after the digital mail operator provides the contact information of its team and signs the necessary NDAs, after the appropriate security clearances are completed.

Before production use:

  • test the implementation in accordance with DVV instructions
  • verify compliance with the requirements 
  • correct any shortcomings.

5. Prepare for communications, customer guidance and support

Keep your users informed

A digital mail operator must ensure that its users do not misunderstand the operating logic of digital official messages. Aim for your users to understand both their rights and duties, regardless of which party provides them with the information and whether they are users of Suomi.fi Messages or the digital mail service. DVV does not join advertising campaigns of the digital mail operators. 

Digital mail operators may use preferred DVV terminology to ensure uniform customer communications.

  • Suomi.fi Messages is a centralised solution for public administration organisations to send messages to individuals and companies. 
  • A digital mail service can be used to read the Suomi.fi Messages inbox along with digital mail from other senders.
  • A message, i.e. a digital official message, is a message in Suomi.fi Messages that can be read in all approved digital mail services. An individual may also receive digital messages from the authorities in other channels than Suomi.fi Messages. Please note: never use “Suomi.fi Message” for an individual message.
  • The authorisation to display messages is granted by the user to the digital mail service, based on which the content of the user’s Suomi.fi Messages inbox can be shown in the digital mail service. The user grants this authorisation through the digital mail service, and it can be revoked in Suomi.fi Messages settings.

A glossary of Suomi.fi Messages terminology is available in the Suomi.fi Interoperability Platform.Opens in a new window.
