Create an email address
Go to the Domain name / Mailboxes & redirections menu and click on “Create”.
In the mailbox creation form, choose a Standard mailbox (10 GB) or a Premium mailbox (50 GB). Then fill in:
mailbox: specify the first part of the address, what comes in front of the “@” sign.
Do not use accented characters and the only globally recognized special characters are the hyphen (“ - “) and the period/full stop (“ . “).
Password: choose a strong password: http://passwordsgenerator.net/
Aliases: this field is optional and allows you to create aliases (variants) of the chosen address.
Once the specific contract has been accepted and the form validated, your mailbox will be created in a few seconds. You can access your addresses via one of our webmails or your messaging application (generally called a “mail client”).
Optional alias
You can also optionally create aliases for your email address. An alias is an "alternative" email address for your primary email address, which will redirect emails sent to that alias to your mailbox:
