Never Miss an Attendee RSVP Change
Track who's coming to your meetings in real-time. Every time an attendee updates their RSVP status, Notis sends a Slack reminder so you can reprioritize on the fly.
Trigger
Attendee Response Changed
Polling trigger that fires when any attendee's RSVP changes to accepted, declined, or tentative. Returns attendee info and current status.
Action
Create a reminder
Creates a slack reminder with specified text and time; time accepts unix timestamps, seconds from now, or natural language (e.g., 'in 15 minutes', 'every thursday at 2pm').
Why this helps
Neurodivergent founders often struggle to track meeting confirmations across multiple platforms. When attendees RSVP changes get buried in email or calendar notifications, critical attendance shifts are missed, leading to wasted prep time or understaffed meetings.
- Instant visibility into who's attending without switching contexts
- Adjust meeting prep or cancel prep work immediately if someone declines
- Reduce time spent manually checking attendance confirmation
- Catch last-minute cancellations before the meeting starts
Setup
Build it in a few focused steps.
- 1Connect your Google Calendar and Slack workspace to Notis once (via the portal).
- 2Open the Notis portal, go to Automations, and create a new automation. Name it 'Attendee RSVP Tracker'.
- 3In the Prompt field, write: 'When someone changes their RSVP to my calendar event, send me a Slack reminder with their name and new status (accepted, declined, or tentative).'
- 4Set the Trigger to 'Attendee Response Changed' from Google Calendar.
- 5Choose the Slack channel where you want run reports (e.g., #automations or your personal DM with Notis).
- 6Test it by asking a colleague to accept or decline an upcoming meeting invite.
Questions about this workflow
Will this trigger for every attendee on a meeting?
Yes. Notis monitors all attendees on any event in your connected calendar, so you'll be reminded whenever any of them change their status.
Can I filter by meeting type or importance?
In your plain-language prompt, tell Notis: 'Only remind me about meetings with 5+ attendees' or 'Skip team standups.' Notis will filter based on your instructions.
What time will I get the reminder?
Immediately when the attendee clicks RSVP. No delays.
