Automation quotas and limits
Automation is available in all Trello Workspaces. Automations use automation runs and operations each time they’re triggered. Paid plans have larger quotas so you can automate more of the busy work.
Automation runs and operations
Automation run: Every time an automation button is pressed, or an automation is triggered, it counts as one automation run.
Operation: Every action taken by an automation counts as at least one operation.
Each automation run may use more than one operation. For example, an automation may set a label and a due date on a card. This counts as two operations every time it runs. Most actions consume one operation, but some actions, like sorting a list, may require multiple operations.
Pooled quotas
All Trello Workspace plans have pooled quotas. The quota is shared between all boards in a Workspace. Each time an automation triggers, it uses one automation run, and however many operations are needed for that automation’s actions, which are drawn from the shared Workspace quota.
Automation quota by plan
| Free | Standard | Premium | Enterprise |
|---|---|---|---|---|
Automation runs per month | 250 | 1,000 | Unlimited | Unlimited |
Operations per month | 2,500 | 20,000 | 150,000, with an additional 10,000 per user, capped at 250,000 per Workspace | 150,000, with an additional 10,000 per user, capped at 250,000 per Workspace |
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).
View automation quota usage
You can view your Workspace’s automation quota usage from any board in the Workspace.
To open the usage log:
Open any board in a Workspace, then open the board menu ()
Select Automation
Select Activity ()
Select the Workspace activity tab
You’ll also find the the number of automation runs and operations that have been used this month.
You’ll also find the Workspace name, and the plan that Workspace is subscribed to. The automation quota is determined by the Workspace’s plan.
Other limits
To protect our systems and prevent strain on Trello’s resources, Trello also currently limits:
The maximum number of automation runs per minute
The number of cards a single automation run will affect
The total number of actions and operations performed by a single automation run (currently 20 for all plans)
Automation enforces a maximum number of emails that can be sent with the send email action. There is a limit of 50 recipients per action. Note that the quota is consumed per email sent, not per action, so sending an email to all board members will consume 1 email quota per board member.
We sometimes need to change these limits without notice, and reserve the right to do so to improve the performance of the system.
Storage limit
There is a limit to the total number of automations each user can create. Rather than a fixed number of automations, the limit is a total of 64000 characters, shared among all automations you create.
64000 characters is equal to about 750 average length automations.
Most Trello users will never reach this limit, but if you plan on making a very large number of automations with a single account, it is possible. This is a database limit, and unfortunately can’t be removed or raised.
The legacy Butler bot
The legacy 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.
