Email Verifier

Why this helps
Verification can be forgotten when it lives as an extra manual step between finding an address and using it.
- Makes email verification an explicit team signal.
- Returns the result alongside the address context.
- Helps reduce avoidable address-checking delays.
Setup
Build it in a few focused steps.
- 1Connect Slack and Hunter to Notis once in the portal.
- 2Create the automation in the portal or ask Notis conversationally.
- 3In one instruction, specify the agreed reaction and ask Notis to verify the email in the reacted-to message using Hunter.
- 4Select Message Reaction Added as the trigger and choose a channel for run reports.
- 5Test by reacting to one real message containing an email to verify.
Questions about this workflow
Should the reaction be used for every email in a conversation?
Use it only when the reacted-to message clearly contains the single address that should be checked.
Does the result prove the address is safe to contact?
It provides a deliverability signal. It does not guarantee inbox placement or determine whether outreach is appropriate.
