Mail size and disk space limits

This guide details the limits of your email in terms of size (message size and disk space) set up as part of the Infomaniak email offers and guides you on how to check your storage usage.

Email Size Limits

Storage

The total volume of your emails is unlimited, both in terms of the number of messages and the space it occupies in storage.

Only users of free email accounts @ik.me (+ etik.com, etc.) cannot exceed 20 GB of storage.

There is no time limit for message retention in the inbox or subfolders, except for an email that would be deleted, marked as spam, or moved manually/automatically to the "Trash" or "Spam" folder (or one of its equivalent names like "Deleted Items," "Trash," "Junk," etc. - non-exhaustive list)...

In this case, the email is automatically deleted after 30 days with no possibility of recovery.

Backups made by Infomaniak also have a retention period.

It is not recommended to keep more than 4,000 to 5,000 messages per folder (slowing down message indexing). It is therefore advisable to move your messages to subfolders, which also makes them easier to access. You can do this manually or set up automatic sorting rules.

Email Size

The maximum size of an email for sending and receiving is 200 MB (including both attachment size and the text and image(s) in the email).

Attachments

With Mail, the attachment size limit is 25 MB; beyond this, a Swisstransfer link is generated (learn more).

Viewing Total Size from Mail

To do this:

1. Log in to Mail Infomaniak (mail.infomaniak.com) from a web browser like Brave or Firefox
2. Check or select the relevant email address from the dropdown menu in the left sidebar
3. Click the action menu ⋮ to the right of the relevant item in the table that appears
4. Click Email Address Settings
   
5. Click Refresh in the Storage section to display the mailbox size
   

Still Having Problems?

In cases where the recipient's email address is not hosted with Infomaniak, you may receive an error message when sending the email. This can take various forms, such as: "Recipient address rejected: 5.2.2 Over quota 554 5.0.0 Service unavailable."

This may indicate that your recipient's mailbox is full and they can no longer receive emails or that the email you are trying to send is too large.

You need to contact your correspondent and ask them to empty their mailbox or inquire about the maximum message size you can send to them.
