Automatic email alerts for canceled calendar events
Stop wasting prep time on meetings that get canceled at the last minute. Notis emails you instantly when an organizer cancels, so you know immediately.
Trigger
Event Canceled or Deleted
Triggers when a Google Calendar event is cancelled or deleted. Returns minimal data: event_id, summary (if available), and cancellation timestamp.
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 prepare for a meeting, set aside time, maybe even write notes—then find out it was canceled hours later. The organizer didn't explicitly notify you, and you never thought to check your calendar again.
- Protect your focus time by getting instant notice instead of realizing mid-meeting that it's been canceled
- Reclaim mental energy by not re-reading notes or prepping for events that won't happen
- Reduce confusion about your actual schedule without having to manually check your calendar
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Gmail to Notis via the portal
- 2Ask Notis 'Email me when a meeting gets canceled' or use the automation builder
- 3Select the trigger: Event Canceled or Deleted
- 4Choose your notification channel (email, Slack, or text)
- 5Test by scheduling a dummy event, then deleting it to see the alert
Questions about this workflow
Will I get an alert for every meeting cancellation?
Yes, for any event on your calendar that's canceled or deleted. If you're frequently invited to large group calls that change, you'll get notifications for each one.
What information is included in the email?
Notis sends you the meeting title, the time it was scheduled for, and a confirmation it's been canceled. That's usually enough to update your mental schedule.
Does this work for events I organize vs. events I'm invited to?
It works for any event on your calendar, whether you organized it or were invited. The moment it's deleted, you get an email.
