Groups policies and limits

Groups logo

As a security measure, all Google Apps groups have limits on message activity, invitations and size, and membership. If you reach one of the limits, you are prevented from the activity whose limit you reached. The restriction typically lasts an hour, but can last as long as 24 hours.

The following limits apply for Google Apps for Work or Education accounts. The value of these limits may change without notice in order to protect Google's infrastructure.

Message limits

All recipient counts refer to the total number of recipients, not the total number of unique recipients. For example, if one of the group members is another group consisting of two users, it counts as three recipients (the group and its two members).

Note: Limits for Google Apps for Work trial users are lower.

Type Description Limit
Total recipients per group Maximum number of group message recipients 6,200,000 per hour
Total external recipients per group Maximum number of group message external recipients 5,000 per day
Total external recipients per domain Maximum number of external recipients for all groups in a domain* 10,000 per day
Total inbound emails per group Maximum number of email messages the Google Groups server accepts per group** 300 per 5 minutes
Total message size Maximum total gigabytes (GB) for all group messages 2.4 GB per hour
Total messages per sender to a specific group Maximum number of messages a sender can send to a specific group 1,800 per hour

* External recipients are recipients that are outside of your domain. For customer accounts with multiple domains, recipients in all associated domains count as internal recipients. The limit on external recipients increases with the size of the Google Apps account; a customer with 20,000 users has a limit larger than 10,000 per day.

** If archiving is enabled for the group, then the maximum number of messages received is 1 message per second.

Group invitations and size

Group invitation and size limits only apply to actions performed in the Groups web interface. Domain administrators can add more members to a group using the Google Admin console or the Google Apps Provisioning API.

Note: Limits for Google Apps for Work trial users are lower.

Type Description Limit
Joins per day Maximum number of groups a single user can join in a day 30 per day
Creations per week Maximum number of groups a single user can create in a week 5 per week
External member additions per day, per group Maximum number of external members* that can be added to a single group in a day 100 per day, per group
External member invitations per day, per group Maximum number of external members that can be invited to a single group in a day 500 per day, per group

* External recipients are recipients that are outside of your domain.

Membership

If you are the owner or manager of a group, it counts as two memberships, one as a group member and one as the owner or manager. A user is an indirect member of a group if they belong to a different group that's nested in the group.

Type Description Limit
Direct membership Maximum number of groups a user can be a direct member of 2,000
Combined direct and indirect membership Maximum number of groups a user can be a direct or indirect member of 5,000

Examples

  • You can be the owner or manager of a maximum of 1,000 groups.
  • You can be an indirect member of 3,500 groups and a direct member of 1,500 groups.
  • You can be the manager of 500 groups and and a direct member of 1,000 groups.
  • You can be the owner of 1,000 groups and an indirect member of 3,000 groups.
