Automatic Apology Messages When Events Are Deleted
Deleted a meeting by accident? Notis sends WhatsApp apologies to attendees immediately, explains what happened, and provides next steps.
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 message
Send a text message to a whatsapp number. note: the message will reflect on the recipient's phone number only if they have texted first.
Why this helps
You accidentally delete a calendar event; attendees get confused by the sudden removal and don't know if the meeting is cancelled or rescheduled.
- Saves reputation: immediate explanation prevents confusion and frustration
- Fast recovery: attendees know what happened instead of wondering
- Professional touch: apology message shows care and minimizes relationship damage
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and WhatsApp business accounts to Notis.
- 2Create a new automation: 'When an event is deleted or canceled, send attendees a WhatsApp message: Sorry, [event name] was deleted by accident. New time coming shortly.'
- 3Set the trigger to 'Event Canceled or Deleted'.
- 4Pick your run-report channel.
- 5Test by deleting a dummy event and verifying attendees receive the apology message.
Questions about this workflow
How does Notis know if a deletion was accidental vs. intentional?
It can't distinguish—all deletions trigger the automation. You can refine it manually afterward (skip sending if deletion was intentional) or just let it send apologies for all deletions.
What if I accidentally send the apology and the deletion was intentional?
Send a follow-up: 'Actually, the meeting is still cancelled' or reschedule for later. Attendees will understand from context.
Can I customize the apology message based on meeting type?
Yes. For example, 'If a client meeting is deleted, send a more formal apology. If an internal standup, send something casual.'
