I created a SharePoint 2013 type workflow (using SharePoint 2016) in SharePoint Designer. When a task is assigned then user is receiving two emails. One email is my custom email which I have set in workflow and other is system generated. The other email seems like the one which is sent by SharePoint when you are subscribed to Alerts on a list. But the thing is I haven't done any subscription so why users are receiving this email and how to make it stop?

This is a Dev environment and I have just created this site and workflow.

    Hi @Frank Martin , there is one more setting to check in case it helps:

    Please open the Workflow task list via SharePoint Designer 2013 > Workflows > the workflow you are using > Open task list under Customization > Preview in Browser on ribbon.
    Navigate to LIST > List Settings > Advanced settings > E-Mail Notification and switch this setting to No.

    Please check and confirm:
    There is an option “Modify my alert settings” in the email (also can be found in the screenshot you provide), which will bring you to the “My Alerts on this Site” page directly when being clicked on.
    Please click on the link in the email and see if there is any alert listed on this page. Delete the alert if any.

    You may also check the alerts on user’s behalf as a site collection administrator via Site Settings > User Alerts (under Site Administration).
