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

Introduction

• For sending emails to a large number of recipients, the Newsletter tool is the most suitable.
• Upon written request, which must be justified and authenticated, it is possible to modify these security rules for a specific paid email address.
• These measures protect you from malicious use of your computer or account.
• Quota calculation (sliding window): the limits (below) are not reset at midnight but are calculated in real time over a 24-hour window; each message sent "occupies" a slot in your quota and is automatically freed up 24 hours after it is sent.
  • If you send messages throughout the morning until you reach your limit at 11 a.m., your sending rights will gradually become available 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.

Sending limits per 24 hours

⚠ Number of outgoing emails possible per 24 hours:

* The maximum number depends on the email plan to which the address belongs.
