Check phone details when follow-up is marked

Turn a clear team signal into a verified number, so contact follow-up has fewer avoidable delays.

Trigger

Message Reaction Added

Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.

Action

Phone Verification API

Tool to verify phone numbers through syntax, range checks, and network verification. Use when you need to validate a phone number's format, line type, and connection status. Returns verified number details including line type, connection status, and formatted representations.

Why this helps

Phone validation can become an extra chore that slips between deciding to follow up and actually doing it.

  • Validate phone details at the moment follow-up is signaled.
  • Return formatted number and line information for review.
  • Make the next contact step easier to start.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Addressfinder to Notis once in the portal.
  • 2Create the automation in the portal, or ask Notis to set it up conversationally.
  • 3Tell Notis in one instruction to verify phone numbers in a message when the agreed reaction is added and report the result.
  • 4Choose the Slack reaction-added trigger and a run-report channel; test with one real number message.
