What's Wrong?

I have a scheduled Routine in Claude Code desktop on macOS with both "Push notification" and "Email" checked under Notifications. When the routine completes and calls the notification tool, the push notification arrives correctly, but no email is ever received — not even in spam. This happened consistently across multiple runs on the same day.

What Should Happen?

Both configured notification channels (push + email) should deliver when a routine run triggers a notification, since both are enabled in the routine's Notifications settings.

Steps to Reproduce

1. Create a scheduled routine (recurring trigger, e.g. daily/weekdays at a set time).
2. In the routine's Notifications tab, check both "Push notification" and "Email".
3. Let the routine run on its schedule (or trigger it) so it reaches the point where it sends a completion notification.
4. Push notification arrives on mobile/desktop as expected.
5. Check the email inbox associated with the account, including spam/junk folders — no email arrives.
6. Repeat across multiple separate runs on the same day — same result each time: push works, email never arrives.
