Understanding the 24-hour outgoing email limit

This guide details the security measures implemented as part of the Infomaniak email offers to detect abusive and abnormal use of an email address.

 

Preamble

  • Upon written request, justified and authenticated, it is possible to modify these security rules for a specific paid email address.
  • For sending emails to a large number of recipients, the Newsletter tool is the most suitable.
  • These measures protect you from malicious use of your computer or your account.
  • Quota calculation (sliding window): the limits (below) are not reset at midnight but calculated in real-time over a 24-hour window; each sent message "occupies" a space in your quota and is automatically released 24 hours after it is sent.
    • If you send messages throughout the morning until you reach your limit at 11 AM, your sending rights will be gradually released the next morning, as each message reaches its 24-hour age.
  • 1 message sent to 2, 42, or 99 people in CC/BCC counts as 2, 42, and 99 messages, respectively.
