Turn a simple reaction into an email check
A reaction can be a low-effort way to flag an address for validation without adding another instruction to write.

Action

Why this helps
Remembering which contact needs checking can create one more open loop in a crowded Slack channel.
- Flag an address with a quick, visible signal.
- Keep the request attached to the original Slack message.
- Reduce the need to remember a separate validation task.

- 1Connect Slack and Emaillistverify to Notis once in the portal.
- 2Create an automation in the portal or ask Notis in plain language.
- 3Tell Notis in one instruction to verify the email in a message when you add your chosen reaction.
- 4Select Message Reaction Added, set the channel and emoji filter in the trigger, and pick a run-report channel.
- 5Test by reacting to one real Slack message containing an email.
