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 classic email or a newsletter service through its unique features:
  • It allows users to subscribe to a “subscription” via a simple registration form, the code for which is provided.
  • It allows one or more designated users (moderators) to accept or reject registrations, send messages to subscribers, and then moderate members' replies before they are published.
  • It allows users to contribute to the discussion by replying to a single address that automatically redistributes incoming messages to other members.
  • It offers a simple unsubscription option that complies with GDPR standards.
• Please read this other guide regarding the service's limitations.

Accessing the mailing list

If the mailing list service was activated in the past, it can be accessed 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 relevant product.
3. Click on Mailing list in the left-hand menu:
   

Creating and configuring the mailing list

To create a new mailing list:

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

Alternatively:

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 already exist on the Mail Service of the domain in question (and cannot be created or 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 determine 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 “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. Setting “who can write to the list” is just as important:
   • You can use the service as a one-way tool, for example, for disseminating information, or as a multi-way tool, for exchanging information and holding discussions, including with non-members (with moderation)...

8. Click on Advanced Options.
   
   

9. It is possible to 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 coming from the list's email address itself
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 the user subscribes to the list.
12. Allows you to customize a message that will be automatically sent to an email address when the user unsubscribes from the list.
13. Click the button to save.

Subscription (according to the settings in point 6 above)

• Subscribers can subscribe 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 receive a notification email whose content can be customized.
• If the subscription made by a subscriber needs to be validated by a moderator, the latter receives an email:
  • The moderator approves the request by clicking on the "mailto:" link, 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 stop line to prevent the execution of other scripts, for example in the case of a signature.
• If the subscription made by a subscriber needs to be validated by the subscriber himself, the latter receives an email to which he must reply (by clicking on the link to create a new reply email that is pre-filled):
  
  • And in this case, the moderator receives the request at a later stage, after validation by the subscriber, and must reply to it to validate the subscription (the easiest way is always 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.
• When unsubscribing, a confirmation request message is sent to the user.
  • The user approves the request (by clicking on the “mailto:” link, 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 their 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 “mailto:” link, which generates a new message that can be sent to the email address in the format list-name-request@list-domain.
• If a moderator is also a member of the list, they will not receive the messages they send themselves, but they will obviously receive messages sent by other moderators.

Forms (subscription/unsubscription)

To allow visitors to a website to subscribe to your list, you can generate a code that can be inserted on the website of your choice; 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 can 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 indicates the number of errors encountered by an address and the date:
