Google Apps email sending limits

If you exceed the Google Apps email sending limits, you may 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

To keep our systems healthy and your accounts safe, Google Apps 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. After reaching one of these limits, a user can't send new messages for up to 24 hours, but they can still access their account and receive incoming email.

These limits may change without notice to protect Google's infrastructure. Limits per day are applied over a rolling 24-hour period rather than a set time of day.

User locked out of their account? Google Apps administrators can check the Users section of your Google Apps Admin console to find details on which limits were reached and when access will be restored. In some cases, an administrator can reset the Gmail suspension.

The following sending limits apply:

Limit type Description Limit
Messages per day Daily sending limit* 2,000 (500 for trial accounts)
Messages auto-forwarded Messages automatically forwarded from another account; not included in the daily sending limit 10,000
Auto-forward mail filters Account filters that automatically forward mail 20
Recipients per message Addresses in the To, Cc, and Bcc fields of a single email* 2,000 (500 external)
Recipients per message (sent via SMTP by POP or IMAP users) Addresses in the To, Cc, and Bcc fields of a single email* 100
Total recipients per day Individual addresses count in every mail sent; 5 emails sent to 10 addresses count as 50 recipients* 10,000
External recipients per day Email addresses outside your primary domain, including domain aliases and alternate domains 3,000
Unique recipients per day Individual addresses count once a day; 5 emails sent to 10 addresses count as 10 unique recipients* 3,000 (2,000 external, 500 external for trial accounts)

*Applies to both internal and external recipients

Using the SMTP relay service? If your organization uses the SMTP relay service to route outgoing mail through Google, sending limits are different. Learn more about the sending limits for the SMTP relay service.

How long does it take to upgrade from trial limits?

At the end of your 30 day trial period, your sending limits will be automatically increased when your domain is cumulatively billed for more than $30 USD (or the same amount in your currency). To expedite this process, you can manually prepay this amount as suggested here. It will take up to 48 hours to upgrade your sending limits after you submit the manual payment.

How long does a suspension last?

If an account reaches a sending limit, the restriction on sending new mail typically lasts for about 24 hours. After this period, sending limits are automatically reset and the user can resume sending mail.

Accounts that are detected as sending spam may be permanently restricted from sending email. See Google's Spam and abuse policy.

Sending mail from another address
  • In mail delegation, the sending limits of the delegator are applied to messages sent.
  • When sending mail from a different address, the primary account's message limits are applied.
  • Messages sent via Gmail's vacation responder (for example: Out of Office automatic replies and messages sent via forwarding rules) are counted toward the sending limits of the primary account.
Recommendations for sending bulk email

To send a large amount of mail such as for a marketing campaign, consider one of the following alternatives:

  • Stagger mass communications over the course of two days. For example, send messages to one group of recipients, wait 24 hours, then send to another group.
  • Google Groups for Business. Send mail to many email addresses using a single group address. For example, administrators can use Groups to contact all users in their organization by adding everyone in the domain to an email list. See also Google Groups limits.
  • Google Apps Marketplace. Download compatible applications. (Marketplace solutions are created by 3rd party developers for a general audience. Google does not offer technical support for Marketplace Apps.) Here are results for "email marketing."
  • Google App Engine for Mail. (For developers) Increase mail limits by building a customized application.
  • If you have a local mail server, send to the recipients directly to avoid sending limits. This local server should also be added to your SPF record to stop the messages from being marked as spam.
  • If email recipients report messages as spam, review our bulk sending guidelines and best practices to ensure that all the recipients are willing to receive the emails. You may also want to check email settings for any incorrectly configured forwarding rules or filters causing these messages to go out.
