Give webinar follow-up a clear visual cue
When a participant appears in the report, mark the related Slack follow-up message so the next step is easy to spot.
Trigger
New Webinar Participant
Triggers when a new participant appears in a past webinar's participant list.
Action
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
Why this helps
A reminder to contact webinar attendees can disappear inside a long event planning conversation.
- Make an existing follow-up message stand out.
- Keep the attendee task tied to the team's event conversation.
- Add visibility without creating another channel or message.
Setup
Build it in a few focused steps.
- 1Connect Zoom and Slack to Notis once in the portal.
- 2Create an automation and tell Notis in plain language which Slack attendee follow-up message to mark when a new webinar participant is reported.
- 3Select the Zoom New Webinar Participant trigger and choose a channel for run reports.
- 4Test with a participant list from a real past webinar and the intended Slack message.
Questions about this workflow
Does a reaction notify the attendee?
No. It marks a Slack message for people who can access that conversation.
Can I use this alongside a reminder?
Yes. Describe the desired workflow clearly, or create a separate automation for a Slack reminder.
