- Surface a potential delivery issue before replying.
- Keep support follow-through easier to track.

- 2Create the automation in the portal or ask Notis conversationally.
- 3Write one prompt telling Notis to verify customer emails shared in the support channel for follow-up.

- 5Test with one real customer address posted for checking.
