Why this helps
Decisions buried in a busy channel can leave a domain check waiting for someone to remember the next step.
- Use a visible team signal to start the check.
- Check domain configuration and catch-all behavior.
- Keep the request and its context in the Slack thread.
Setup
Build it in a few focused steps.
- 1Connect Slack and Bouncer to Notis once through the portal.
- 2Create an automation through the portal or by asking Notis in plain language.
- 3Tell Notis to verify the domain named in a reacted-to message and report its Bouncer result.
- 4Choose Message Reaction Added as the trigger, then select the channel and emoji in the trigger settings and choose a run-report channel.
- 5Test by reacting to a real message that names a domain.
