Exclude yourself from notification emails of events you started
TFS 2018
When you create a team role-based notification subscription, you can choose the option, Skip initiator. The initiator of the event that triggers the email doesn't receive the notification.
For example, if your team has a subscription for a pull request created event, the user who creates the pull request in the project doesn't receive this notification email. Other members of the team receive the notification email.
This option is good for users who don't want notifications of events that they trigger. However, some users may feel left out when their teammates receive the email and they didn't. Let your team decide which option is best.
Note
For on-premises Azure DevOps Server, configure an SMTP server for team members to see the Notifications option from their organization or user profile menu and to receive notifications.
