Email receiving limits

To keep systems healthy and accounts safe, Google limits the number of email messages users can receive per minute, hour, and day. Setting up accounts to receive frequent automated messages, such as log files, increases the likelihood of reaching the limits.

If an account reaches the limit, a user can't receive any new email and may experience general account problems, such as slow searching. All incoming messages bounce back to the sender.

Locked out of your account? G Suite administrators can check the Users section of your Google Admin console to find details on which limits were reached and when access will be restored. Sometimes, an administrator can reset the Gmail suspension.

The following table shows limits for different time periods. These limits apply to G Suite and Education editions. The value of these limits may change without notice in order to protect Google’s infrastructure.

Description All email addressed to the account. Might appear as threaded and non-threaded Gmail conversations.
Per minute 60
Per hour 3,600
Per day 86,400
Size limit

You can receive emails of up to 50MB.

Note: To send file attachments larger than 25MB, use Google Drive or other file-sharing services.


How long does a suspension last?

If an account reaches a receiving limit, the restriction on getting new mail typically lasts for about 24 hours. After this period, receiving limits are automatically reset and the user can resume receiving mail. After an account reset, a user can't recover any messages sent to the account during the restricted period.

Recommendations

Use Google Groups

To avoid reaching the receiving limit, send message logs and automated emails to Google Groups. Using Groups, you can use a web interface to read large or frequently mailed announcements that quickly hit the receiving limits of your email account. Sending automated emails to a Groups account reduces the load on your email account, allowing you to take advantage of the receiving limits for both email and Groups.

Also, subscribe to the daily digest forms of heavily trafficked email lists.

Accounts best practices

  • Avoid using a single account for multiple users.
  • Use Google Groups for sharing mail.
  • Map 10 or fewer email aliases per account.
  • Use groups to create shared mailboxes or to allow many people to send and receive mail with a single address.

Avoid using catch-all accounts

Spammers often try to guess email addresses in your domain. When they guess incorrectly, the spam is delivered to the catch-all address. The high mail volume can quickly exceed Gmail’s limits.
