Log Event Attendees Automatically from Slack DMs
Event registration shouldn't require a separate form. When attendees register via DM, Notis creates a new attendee row in your event sheet so you have a real-time list without manual data entry.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Action
Create spreadsheet row
Inserts a new, empty row into a specified sheet of a google spreadsheet at a given index, optionally inheriting formatting from the row above.
Why this helps
Collecting event registrations across email, Slack DMs, and forms is chaotic for ADHD founders, leading to duplicate registrations or forgotten details.
- Registration happens where people are (Slack)
- No separate form or tool needed
- Real-time attendee list in Sheets
- Automatic deduplication of registrations
- Easy to follow up with attendees
Setup
Build it in a few focused steps.
- 1Connect Slack and Google Sheets to Notis.
- 2Create a new automation with 'Direct Message Received' as the trigger.
- 3Write your prompt: 'When someone registers for an event in a DM, create a new row in my event attendees sheet with: date of registration, name, email, company, and any special requests they mention.'
- 4Publish a simple registration message in your #events channel: 'To register, DM @Notis: Register for [Event Name]'
- 5Test with a few registrations to ensure data captures correctly.
Questions about this workflow
Can I extract email from Slack profiles automatically?
Yes. Notis can pull the email from their Slack profile if it's available, or ask them to provide it in the DM.
What if someone registers twice?
You can ask Notis to append a note flagging potential duplicates based on name or email, then manually review weekly and delete duplicates.
Can I send attendees a confirmation message after they register?
Yes. You can set up a separate Notis automation that sends a confirmation DM when they register, confirming receipt and sharing event details.
