These limits are for your entire Google Workspace account: all your organizational units and domains combined.
- 5 MB. This limit is the combined size of all Gmail settings in your Google Workspace account, after you save them and they’re compiled by the system. If you reach this limit, you can’t save additional settings.
- 1,000 settings (not over 5 MB).
- 1,000 characters per description
- 1,000 expressions
- 4,000 characters per expression
- 100 recipients
- 100,000 entries
Email addresses: The number of addresses for:
- Approved and blocked senders.
- Apply or bypass lists, which are lists that are used to apply settings to specific addresses or bypass settings for specific addresses.
- 2,000 address lists
- 100,000 addresses per list
