How to send an email when a Planner task is completed using Power Automate

Microsoft Planner has built-in notifications for assigned tasks, reminders, and overdue tasks, but sometimes you’ll want to be kept in the loop when important tasks are completed as well, even when the task isn’t assigned to you specifically.

We can create a Power Automate flow to accomplish this. In this post, I’ll cover three topics:

  • Creating a flow from a template
  • Creating a flow from scratch
  • Sending notifications to task assignees

Use a Power Automate template to send an email when a Planner task is completed

First, you’ll need to sign in to Power Automate using your work or school (not personal) Microsoft account. Then follow these steps:

  1. Select Templates and search for “send email Planner completed” (or click this link)

  1. Enter the email address(es) to which notifications should be sent when tasks are completed in the selected plan. You can also customize the message body simply by clicking in the body field and entering your own text and/or dynamic content.

  1. Click Save (at the bottom or upper right)
  2. Go to the specific plan for which you’ve created the flow (Hint: you’ll find it at and complete a task to test it. You may want to create a fake task for your test.

  1. Check the email inbox for the address(es) you entered in step 4. You should have received your custom email. Note: It may take a few minutes for it to appear.

Note: Your email will come through with the “Completed by” individual’s ID instead of their display name. Follow the steps in this post to change the ID to display name.

Video demonstration using a template (see bottom of post for non-template):

  5. Enter a subject (perhaps using dynamic content such as the task title in the subject – see video at bottom of post for demonstration)
  6. Enter a message body (again, using dynamic content to insert details such as title and completed time)
