Why this helps
An incorrect vendor email can derail small but time-sensitive tasks such as access setup or invoice coordination.

- See more than a basic valid-or-invalid result.
- Reduce last-minute contact troubleshooting.

- 2Create the automation in the portal or ask Notis conversationally.
- 3Use one plain-language prompt telling Notis to run a detailed check when a vendor email is shared for review in Slack.

- 5Test with one real vendor email.
