Use one reaction to move a contact detail from review to verification.
Trigger
Message Reaction Added

Action
Email Verification API
Tool to verify email addresses including syntax validation, domain existence, and email account verification. Use when you need to validate an email address before sending messages or storing contact information.
Why this helps
Contact checks get forgotten when approval happens in a separate thread or task list.
- Make review intent explicit
- Verify only approved contact details
- Reduce missed data quality checks
