I show you how to set up a subscription email in Tableau Prep so you get notified when a flow has finished running. Introduced in 21.4, this lets you know exactly when a data source has been refreshed so you can take your next step.

## Key takeaways

- Flow completion subscriptions arrived in Tableau Prep with the 21.4 release
- You need an existing scheduled task on the flow before you can create a subscription, as the subscription attaches to that task
- Set one up via the Subscriptions tab on the flow, choosing a frequency, recipients, subject and optional links to the published data source
- If you pick a schedule that already has a subscription it won't create a duplicate, but a new schedule will show as a separate entry
- The completion email includes the site and flow name plus clickable links straight to the data source
