Send messages from another email address
This guide explains how to set up a different sender and reply-to address from the email address used. This is useful for working with one of your email aliases or synonymous domains.
This will work with Infomaniak Mail, Infomaniak Webmail, as well as most email software.
Prerequisites
- Own an Infomaniak email address (excluding free email offers like @ik.me + ikmail.com, etc.)
- The secondary email address that can be used must have been added as:
- either an email alias (e.g., aa@… instead of anna.alpha@…)
- or synonymous domains (e.g., …@short-dom.xyz instead of …@this-is-a-super-longest-domain.xyz)
Setting the sending address in Mail
To access the options for sending addresses:
- Log in to Infomaniak Mail (mail.infomaniak.com) from a web browser like Brave or Edge
- Click on the icon at the top right of the interface
- Verify or select the relevant email address from the dropdown menu
- Click on Signature
- Click on the action menu â‹® to the right of the current signature and then on the icon to edit the current signature
- OR ELSE create a new signature
- Click on Show advanced settings
- The sending address allows you to set the address that will be mentioned as the sender in your recipients' inbox
- Reply-to allows you to receive emails at another address of your choice
- Confirm with the blue Save button (if it remains grayed out, make sure all fields are filled in, especially the full name)
- Compose a new message by selecting the corresponding signature
In the above example, the sending address has been modified but not the reply address. This gives the expected result for the recipient (just look at the headers of the received message for proof).
Add the same secondary address to an email software now, and the effect will be the same.
Setting the sending address in Betterbird
You can configure an email software with any existing email address even if it exists as an alias in your Mail Service. Sending will be done in the same way as with an address defined as the "main" email.
Example in Betterbird software (a fork of Thunderbird):
- Add an account in Betterbird with the correct email settings related to the alias
- Compose a new message
- Once received, the message is well described as being sent from an address that you will know to be an alias:
Attention: there is no link between the settings entered in the Signature part of Infomaniak Mail and email software. Each software has its own settings, and you can for example define a different reply address in each tool.
