To keep systems healthy and your accounts safe, Google Workspace limits the amount of mail one user can send. Limits restrict the number of messages sent per day and the number of recipients per message.
If you exceed a Google Workspace email sending limit, you’ll see an error message, such as:
- You have reached a limit for sending email.
- You reached a Gmail sending limit.
- You exceeded the maximum recipients.
After reaching one of these limits, you can't send new messages for up to 24 hours. However, you can still access your Google account and receive incoming email. You can also access their other Google services. After this suspension period, sending limits are automatically reset and the user can resume sending mail.

As an alternative to email, when sending to large groups, users may wish to create a Google Group. For information on this system, visit this link.
