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 this 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.Free trial account limits
Google Workspace free trial accounts have different limits than paid accounts, and limits aren’t increased during the free trial period. Visit About your Google Workspace free trial to:
- Find out when your trial ends
- Convert your trial account to a paid account
- Cancel your trial account
After you convert from a free trial account to a paid subscription, your account sending limits automatically increase when both of the following are true:
- Your domain has cumulatively paid at least USD 100 (or equivalent)
- At least 60 days have passed since reaching that payment threshold
If you bought your domain from Google, the cost to increase your limits is the cost of your domain plus US 100.
When using Google Groups through a Google Workspace free trial account, you might experience the following limits:
- Your sending limits might be lower than the limits in Sending limits, below.
- You can only send group email to recipients inside your organization.
- You can't turn on autoreplies to people outside your organization, even if they're members of a group.
- You can't allow messages flagged by Google’s spam filters to be posted directly to a group.
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.
- 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.

When you use the Gmail for mobile app in Google Sync mode, the same Sending limits apply as when you use Gmail in a web browser.
When you use the Gmail for mobile app in IMAP mode, the SMTP sending limits apply.
Restore a suspended Gmail account
Administrators can check the Users section of the Google Admin console to find details about which limits were reached. Sometimes administrators can restore access. For instructions, go to Restore a suspended Gmail account.
Accounts that are detected as sending spam might be permanently restricted from sending email. For details, go to Google's Spam and abuse policy.
