Verify email addresses shared in Slack
Turn a Slack-shared email into a quick quality check, with the result sent to your chosen Notis channel.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Verify Email Address
Tool to verify email address format and mailbox existence. Use when you need to validate that an email address is properly formatted and has a working mailbox. Also identifies free accounts and disposable email addresses.
Why this helps
Contact details get buried in busy conversations, and checking them manually creates another task to remember.
- Catch malformed or inactive mailbox details early.
- See disposable and free-account indicators alongside the result.
- Keep the verification outcome in one run-report channel.
Setup
Build it in a few focused steps.
- 1Connect Slack and Data247 to Notis once in the portal.
- 2In Automations, create a new automation and describe checking email addresses shared in Slack and reporting the result.
- 3Choose Slack Channel Message Received as the trigger.
- 4Choose a channel for run reports and test with one real Slack message containing an email address.
