Notification email uses the address you save in Settings. The message follows the app's mail setup, not the storefront theme language.
Add the address you actually read. A task can finish while you are away from the admin, and History is still the place to read the preview.
What the email is for
- Save the email in Settings
- Confirm the checkbox for notifications if you want them
- Use History if you miss a message
- The file itself is not attached as a replacement for the preview
The storefront URL is the copy to share. The email is only a notice that a task ran.
