Why this helps
Small list-quality tasks often get displaced by launch work if they are not captured right away.
- Capture an address check in the flow of review.
- Keep the request beside its Slack context.
- Avoid a separate reminder for a small task.

- 3Write one instruction asking Notis to verify a waitlist email when your chosen reaction is added to its Slack message.
- 4Set Message Reaction Added with your channel and emoji filter, then pick a report channel.
- 5Test by reacting to one real waitlist email message.
