This guide concerns the Mailing List service, which is only offered to Infomaniak users who activated it in the past and for whom a migration of the tool was carried out in early 2025.

Introduction

• The mailing list service differs from traditional messaging or a newsletter service through its unique features:
  • It allows users to subscribe via a simple registration form, the code for which is provided.
  • It allows one or more designated users to act as moderators, accepting or rejecting registrations, sending messages to subscribers, and then moderating members' replies before they are published.
  • It allows users to contribute to the discussion by replying to a unique address that automatically redistributes incoming messages to other members.
  • It offers a simple unsubscription option that complies with GDPR standards.
• Refer to this other guide regarding the service's limitations.

Access the mailing list

If it was previously enabled, you can access the mailing list service within your Mail Service:

1. Click here to access the management of your Mail Service on the Infomaniak Manager (need help?).
2. Click directly on the domain name assigned to the product in question.
3. Click on Mailing list in the left-hand menu:
   

Creating and configuring the mailing list

To create a new mailing list:

• Click the Start button…
  
• … or click the button above your existing lists:
  

Otherwise:

1. Edit an existing list by clicking on its name:
   
2. Click on its Configuration tab:
   

The settings required for the system to function correctly are as follows:

1. A mailing list is based on an email address that must not yet exist on the Mail Service of the domain in question (and which cannot be created on it, nor modified later).
2. You can give the list a name to identify it more easily if you have several lists, or if the email address is not explicit enough.
3. You can also add an additional description.
4. You must specify the email address(es) that will be moderators (i.e., have the highest level of permission on the list).
5. You can define a language for your mailing list.
6. Setting up “who can subscribe to the list” is important:
   • You can specify that the user must confirm their subscription themselves (in addition to a moderator).
7. The setting for “who can write to the list” is just as important:
   • You can use the service as a one-way tool, for example, to disseminate information, or as a multi-way tool, for exchanging information and even holding discussions with non-members (with moderation)...

8. Click on Advanced options.
   
   

9. You can configure whether replies should be addressed…
   • … to the sender, with the sender's email address visible
   • … to the list (everyone receives), with the sender's email address visible
   • … to the list, as if they were coming from the list's email address
10. Allows you to limit the size of emails sent via the mailing list (especially when adding attachments).
11. Allows you to customize a message that will be automatically sent to an email address when a user subscribes to the list.
12. Allows you to customize a message that will be automatically sent to an email address when a user unsubscribes from the list.
13. Click the button to save.

Registration (depending on the settings in section 6 above)

• Subscribers can register by sending a message to the email address in the format list-name-join@list-domain.
• They can also be manually registered by the moderator via the interface, and in this case, they will receive a notification email whose content can be customized.
• If a subscriber's registration needs to be validated by a moderator, the latter receives an email:
  • The moderator approves the request by clicking on a link of the type “mailto:”, which generates a new message that can be sent to the email address in the format list-name-request@list-domain with the subject accept subscriber-email-address and in the body of the message, the line Approved: list-password, possibly adding a line stop to prevent other scripts from running, for example in the case of a signature.
• If a subscriber's registration needs to be validated by the subscriber themselves, they will receive an email to which they must respond (by clicking on the link to create a new reply email that is pre-filled):
  
  • In this case, the moderator will receive the request at a later stage, after the subscriber has validated it, and they must respond to validate the registration (the easiest way is to click on the link):
    

Unsubscription

• Subscribers can unsubscribe by sending a message to the email address in the format list-name-leave@list-domain.
• Upon unsubscribing, a confirmation request message is sent to the user.
  • The user approves the request (by clicking on the link of the type “mailto:”, which generates a new message that can be sent to the email address in the format list-name-request@list-domain, with the subject being the command specified in the confirmation email and an empty body).

Sending/receiving messages

• Each subscriber can create a Mail signature and choose the name to be displayed when sending emails.
• A footer is automatically added to each message sent via the mailing list:
  
• See also the reply-to and from settings in point 9 above.

Message moderation

• To reject a message, the moderator must click on the link of the type “mailto:”, which generates a new message that can be sent to the email address in the format list-name-request@list-domain.
• When a moderator is also a member of the list, they do not receive the messages they send themselves, but they do receive those sent by other moderators.

Forms (subscription/unsubscription)

To allow website visitors to subscribe to your mailing list, you can generate a code that you can then insert into the website of your choice; for example, with Site Creator:

The Form tab allows you to specify the URL to which the user will be redirected after subscribing or unsubscribing:

• If an error occurs while using the form, an error page may display the email address moderation-owner@list-domain, allowing users to contact the moderators.
• A user who is already subscribed to the list can subscribe multiple times without any specific message being displayed.

Error Management

The system displays the number of errors encountered by an address and the date:
