I want to know why I still get regression emails after turning notifications off.
​
​

Regression emails are Issue Workflow notifications, not project Alerts. Turning off Alerts does not stop them.

Open your Issue Workflow notification settings and turn Issue Workflow off for the org, or set the project to Off. Don’t leave it on Default if the org-level setting is still On.

If the email still arrives, check your org’s Alerts for a rule that notifies when a resolved issue becomes unresolved again. That path is separate from Issue Workflow.

Docs note that for regressions, Sentry emails all project team members, not only people subscribed to that issue. See Sentry Notifications and personal notification settings
