Keep event registrants organized
When a team confirms a customer's event registration in Slack, add them to the matching Engage list for organized communication.
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
Subscribe User to List
Tool to create a user and subscribe them to an Engage.so List. Use when you need to add users to a specific list for email marketing or user segmentation. If the user already exists, they will be added to the List without creating a duplicate.
Why this helps
Registrations confirmed in conversation can be missed when the subscriber list is maintained separately.
- Reduce manual list entry
- Keep confirmed registrants grouped
- Make attendee communication preparation easier
Setup
Build it in a few focused steps.
- 1Connect Slack and Engage to Notis once in the portal.
- 2Tell Notis to subscribe only clearly identified, confirmed registrants to the explicitly named event list.
- 3Select the Slack channel message trigger and choose where run reports should appear.
- 4Test with one real confirmed registration and verify the customer and list.
Questions about this workflow
Does an invitation count as registration?
No. Ask Notis to subscribe only after registration is explicitly confirmed.
What if the list has not been created?
Tell Notis to skip the action and report that the matching Engage list is missing.
