Auto-email RSVP status changes from Google Calendar
Stop checking your calendar invite responses manually. Get an instant email alert whenever an attendee accepts, declines, or tentatively responds to your meeting.
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
Send Email
Sends an email via gmail api using the authenticated user's google profile display name, requiring `is html=true` if the body contains html and valid `s3key`, `mimetype`, `name` for any attachment.
Why this helps
You invite people to meetings but lose track of who's actually coming. Checking RSVPs manually eats time and mental energy, especially when responses trickle in throughout the day.
- Know immediately when attendees respond instead of manually checking your calendar
- Reduce decision-making about who's attending by seeing responses in email as they arrive
- Stop context-switching between calendar and email to track meeting confirmations
Setup
Build it in a few focused steps.
- 1Connect your Google Calendar and Gmail accounts to Notis (one-time setup in the portal)
- 2Create a new automation by saying 'Send me an email when someone changes their RSVP on a meeting' or use the portal wizard
- 3Pick the trigger: Attendee Response Changed
- 4Choose where Notis sends run reports (email, Slack, or Telegram)
- 5Test by inviting a friend to a calendar event and changing their RSVP status—you'll get an email alert within seconds
Questions about this workflow
Will I get an alert for every RSVP change?
Yes, one email per person per RSVP state change. If Sarah accepts, then changes to tentative, you'll get two emails. This keeps you fully informed without surprise attendees.
Does this work for events other people are hosting?
Yes. As long as you're invited, Notis will email you when any attendee changes their response. You'll stay in the loop even on meetings you didn't organize.
Can I customize what information goes in the email?
Notis includes the attendee's name, their response status, and the meeting details automatically. Just tell Notis in plain language if you want more or less detail ('include the meeting link' or 'just send me the attendee name').
