To keep systems healthy and accounts safe, Google limits the number of Gmail messages users can send per day, and the number of recipients per message.
If your users exceed an email sending limit, they’ll get 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, users can't send new messages for up to 24 hours. However, they can still access their Google Workspace account, get incoming email, and use their other Google services. After the suspension period, sending limits are reset and users can resume sending mail.
Limits for trial accounts
You can try Google Workspace with a free trial account.
Gmail sending limits
Sending limits can change without notice. Limits per day are applied over a rolling 24-hour period, not a set time of day.
Messages that counts toward user limits
- Messages sent from a user's alternate address, or alias
- Messages sent by delegated users
- Messages sent by Gmail’s vacation responder
Notes:
- Sending limits are different if your organization uses the SMTP relay service to route outgoing mail through Google. Instead, go to sending limits for the SMTP relay service.
- Quotas might be different if you're using Google Apps Script.
- The Google Groups for Business service has its own Gmail message and posting limits.
