Check subscriber addresses raised in Slack
Resolve an individual address question without opening a separate verification tool or losing the thread.
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
Kickbox Single Verification
Tool to verify a single email address via kickbox. use when you need real-time validation of an individual email before critical workflows.
Why this helps
Subscriber cleanup often gets deferred because individual questionable addresses are mixed into other work.
- Resolve one questionable address at a time.
- Keep list hygiene questions attached to the team conversation.
- Reduce avoidable errors before subscriber communication.
Setup
Build it in a few focused steps.
- 1Connect Slack and Kickbox to Notis once in the portal.
- 2Create an automation with a plain-language instruction to verify a subscriber email when the team flags it in the chosen Slack channel, then select the channel message trigger.
- 3Choose a run report channel and test using one real subscriber address raised for review.
Questions about this workflow
Does this clean a full mailing list?
No. The available Kickbox event checks one email address at a time.
How should we flag an address for review?
Describe your team's wording or signal in the prompt so Notis knows which channel messages represent a verification request.
