Action

Why this helps
A mistyped attendee address can undermine reminders and create last-minute admin during an already busy event week.
- Catch address issues before sending an event update.
- Reduce manual verification during event preparation.
- Keep one-off attendee checks close to the planning conversation.
Setup
Build it in a few focused steps.
- 1Connect Slack and Kickbox to Notis once in the portal.
- 2Create an automation in the portal with one plain-language instruction to verify registrant email addresses shared in the event planning channel, and pick the channel message trigger.
- 3Choose a channel for run reports and test with one real attendee address posted in the channel.
Questions about this workflow
Can this verify an entire attendee list?
This uses Kickbox Single Verification for one address at a time, not bulk list cleaning.
Can I limit it to an event planning channel?
Choose the relevant Slack channel when configuring the event trigger if channel filtering is available.
