Automation quotas and limits
Automation is available to all Trello accounts at no additional cost but it has some quotas that are tied to Trello paid. All Trello plans have pooled Workspace/Enterprise quotas. This quota is shared by all the users who belong to the Workspace/Enterprise and it applies to all boards that are part of the Workspace/Enterprise. However, depending on your Trello subscription, you'll have different Automation features and quotas available.
If you belong to a Standard Workspace, Premium Workspace, or Enterprise organization, you'll be able to use automations that work with advanced checklists and Custom Fields. Administrators of Premium or Enterprise workspaces can additionally disable automations on behalf of other users.
Note: The legacy bot (Butler Bot) can't use the operations from Premium or Enterprise accounts. You can move your legacy commands to the built-in version of Butler by using the Butler Bot command importer.
You can check out your Automation quotas in the Automation directory, on the Account tab. For more detail, see Opening the Automation Usage Log.
Quota details
The main Automation quota is automation runs—the number of times your automations can run in a given month. Every click on a card or board button, triggering of a rule, or execution of a scheduled command counts as a command run.
In addition to the command runs quota, the Automation also enforces an operations quota but it is set high enough so you don't generally need to worry about hitting it. Each automation run may use one or more operations. For example, an automation may set a label and a due date on a card, and that counts as two operations every time it runs. Most actions consume one operation, but some actions, like sorting a list, may require multiple operations.
Additionally, if you use the "send email" action, Automation enforces an email quota, which determines the maximum number of emails that Automation will send in a given month. There is a limit of 50 recipients per action. Note that the quota is consumed per email sent, not per action, so for example, sending an email to all board members, will consume 1 quota unit per board member.
The following are Automation quotas for different Trello plans.
| Free | Standard | Premium | Enterprise |
Automation runs per month | 250 | 1,000 | Unlimited | Unlimited |
Operations per month | 2,500 | 20,000 | 10,000 per paid user, capped at 250,000 | 10,000 per user |
Emails per month | 250 | 1,000 | 1,000 per paid user, capped at 100,000 | 1,000 per paid user, capped at 100,000 |
Quota pooling | Pooled for all Workspace members | Pooled for all Workspace members | Pooled for all Workspace members | Pooled across all Enterprise members |
Note: Quotas reset on the first day of every month at midnight GMT (Greenwich Mean Time).
Other limits
To protect our systems and prevent strain on Trello’s resources, we apply some limits such as a rate limit on the maximum number of automation runs per minute, a limit on the number of cards a single automation run will affect, a limit on the total number of actions and operations performed by a single automation run (currently 20 for all plans), and others. We reserve the right to change these limits at any time without notice to improve the performance of the system.
Automation also has a storage limit for the number of automations you can generally create. The available storage depends on the size of created automation—an automation that performs several actions will use more storage than a command that performs only one or two. However, Trello users rarely reach this limit so you don't need to worry about these storage restrictions.
