By default, Tugboat’s comments to a linked git provider display as the person who linked the provider to Tugboat. That means the person who linked the repo will get notifications for every PR where Tugboat automatically posts a comment. If this person does not wish to receive notifications, you can configure a Tugboat bot to post the comments and receive those notifications.
Go to username -> My Projects at the upper-right of the Tugboat screen.

Click into Settings for the repository.
