This guide details the limits of your email regarding size (weight of messages and size of the disk space) set within the framework of Infomaniak's email offers and guides you to check the storage used.

Email box size limit

• The total volume of your emails is unlimited, whether in terms of the number of messages or the space they occupy on the storage.
• Only the my kSuite offer cannot exceed 20 Go of storage.

Limit on the size of each email

• The maximum size for sending and receiving an email is 200 MB (this includes both the size of the attachment and the text and image(s) present in the email).
• With the Infomaniak Web app Mail (online service mail.infomaniak.com) the size limit for attachments is 25 MB. Beyond that, a Swisstransfer link is generated.

Message retention period limit

• There is no time limit for message retention in the inbox or in subfolders, except for an email that would be deleted, marked as spam, or manually/automatically moved to the "Trash" or "Spam" folder (or any of its equivalent names such as "Deleted Items", "Deleted Messages", "Junk Mail", including those spelled in another language, "Junk" for example - non-exhaustive list)… In this case, the email is automatically deleted after 30 days without possibility of recovery.

• Backups performed by Infomaniak have a retention period.
• It is not recommended to keep more than 4000 to 5000 messages per folder (slows down message indexing). It is therefore advisable to move your messages into subfolders, which also facilitates their consultation. You can do this manually or set up automatic sorting rules.

What if there is still a problem?

In the case where your recipient's email address is not hosted by Infomaniak, you may receive an error message at the time of sending the email. This can take various forms, such as for example 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.
