Getting Multiple emails notification for pre-deployment approval

Below are the reasons for getting multiple Emails:

1.     Multiple Notification Subscriptions
You may have more than one notification rule set up for the same event (e.g., pre-deployment approval). Check if:
•     You’ve created overlapping rules at project level, team level, or personal level.
•     Other team members have also set up similar rules that include you.
2.     Multiple Approvers or Environments
If your release pipeline has multiple stages or environments, and each requires approval, you might be getting notified for each one — even if they’re part of the same release.
3.     Group Memberships
If you're part of multiple groups (e.g., DevOps Admins, Project Contributors), and each group is subscribed to notifications, you’ll receive one email per group.
4.     Custom Logic or Extensions
If you’re using custom scripts, webhooks, or marketplace extensions to trigger notifications, they might be duplicating the alerts.
