Google Apps Sending limits

Google has a number of sending limits in place to prevent abuse of our system, and to help fight spam. If one of your mail accounts reaches an abuse limit, the account will be temporarily unable to send mail.

Each Google Apps account can currently send to 500 external recipients per day. Google Apps for Business and Education users can send to 2000 external recipients per day. The email addresses can be distributed among the To:, Cc:, and Bcc: fields. Administrators can contact all user accounts within the domain by adding everyone in the domain to an email list.

Here are a few additional tips:

• Stagger mass communications over the course of two days. For example, send messages to the allotted number of recipients on day one, wait for 24 hours, and send messages to another group of recipients on day two.
• In all editions of Google Apps, an individual message can be sent to a maximum of 500 external recipients at one time.
• If you use an IMAP client (e.g., Apple Mail), you may only send a message to 100 people at a time.
