Why this helps
A single typo in an attendee address can make an invite and its updates disappear without an obvious signal.
- Check attendee addresses promptly after event creation.
- Surface questionable addresses for review before relying on invite delivery.
- Reduce manual copy and paste into a separate validation tool.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Abstract once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a clear name.
- 3Tell Notis to validate attendee email addresses from each new event and report any that are not deliverable.
- 4Choose Event Created as the trigger and select where run reports should go.
- 5Test with one real event that has an attendee email address.
Questions about this workflow
Does this workflow create or change calendar invites?
No. It validates attendee email addresses and reports the result; the available Abstract action does not edit Google Calendar events.
What happens when an address fails validation?
Notis can report the validation result so you can review the address and decide whether to correct the invite.
