To protect the email service and ensure a timely and reliable experience for customers, the hosted email system limits the number of email messages that users can send in a day. Daily limits are applied over a rolling 24-hour period and restrict the total number of recipients to which a user can send messages in this period.
Users are limited to 10,000 total recipients per 24-hour period. Counting recipients is different than counting messages. For example, sending 200 emails that each have 50 recipients is counted the same as sending 10,000 emails that each have a single recipient.
Automated email and spam is restricted at much lower limits to protect the integrity of the system. We reserve the right to change these limits without warning or notice to ensure the integrity of the email service.
