Action
Catch-All Verify
Tool to check if an email domain is catch-all. Use after confirming email validity.
Why this helps
Catch all domains can make verification results harder to interpret during outreach planning.
- Improve interpretation of email checks
- Flag domains needing extra review
- Keep research in the team channel
Setup
Build it in a few focused steps.
- 1Connect Slackbot and Clearout once in Notis.
- 2Create an automation named Check channel domain catch all.
- 3Tell Notis to extract domains from channel messages and report catch all status.
- 4Pick Channel Message Received, choose a report channel, and test with one domain.
Questions about this workflow
Does catch all mean every address is valid?
No, it means the domain may accept mail broadly, so results need additional judgment.
Can it process a URL?
Yes, ask Notis to extract the domain from the URL first.
