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

Introduction

• Number of outgoing emails possible per 24 hours:
  • kSuite Free = 200
  • kSuite Standard = 500
  • kSuite Business = 500
  • kSuite Enterprise = 500
  • my kSuite = 200
  • my kSuite+ = 500
  • Mail Service Starter = 200
  • Mail Service Premium = 500
  • Web Hosting = limit depends on the email service used; otherwise, 50 emails max. via PHP Mail() without authentication.
• For sending emails to a large number of recipients, the Newsletter tool is the most suitable.
• You should also consult these other guides:
  • Limits on the number of recipients per email
  • Storage and email size limits

How are sending quotas calculated?

Quotas are calculated over a rolling 24-hour window and are not reset at midnight. Each email sent is counted for 24 hours from the time it was sent, after which it is automatically released from the quota.

For example, if the limit is reached at 11 a.m., emails sent from that time onwards can only be sent as the previously sent messages reach 24 hours of age. Sending rights are therefore released gradually the next day, and not all at once at midnight.

Why are there sending limits?

Sending limits are applied to protect email services against abusive or abnormal use, including the mass sending of messages from a compromised account.

They also help to limit the risks associated with spam and to preserve the reputation of Infomaniak's servers, in order to maintain good email deliverability.

These limits apply to all emails sent from an address, regardless of the software or application used. Messages addressed to multiple recipients are counted individually: 1 message sent to 2, 42, or 99 people in CC/BCC counts as 2, 42, and 99 messages, respectively.
