Why this helps
Looking up a prospect's website interrupts planning and can leave teammates working from different guesses about the right company.
- Get probable domains from a company name.
- Keep prospect research attached to the Slack mention.
- See confidence scores to guide a quick review.
Setup
Build it in a few focused steps.
- 1Connect Slack and Clearout to Notis once in the portal.
- 2Create an automation in the portal or ask Notis for it in plain language.
- 3In one instruction, ask Notis to use Clearout autocomplete for company names explicitly identified as prospects in a Slack channel and share the domain suggestions.
- 4Select Channel Message Received, choose a run-report channel, and test with one real company mention.
Questions about this workflow
Will it identify every company mentioned?
The Slack trigger fires for channel messages. Ask Notis in the instruction to act only on messages that clearly identify a prospect company.
Are the suggested domains guaranteed?
