Review free email addresses on event attendees
See which attendee addresses use free email providers while the full event details are available.
Trigger
Calendar Event Sync
Polling trigger that returns full event data including details, attendees, and metadata. For real-time notifications with basic info, use Calendar Event Changes (webhook).
Action
Verify Free Email Account
Tool to detect if an email is from a free email service provider. Use after confirming the email format.
Why this helps
Free and work addresses can carry different context, but attendee lists do not always make that distinction obvious.
- Identify free-provider addresses in synced attendee lists
- Keep review tied to full event context
- Spend less time checking domains manually
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Clearout once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis to identify which synced event attendee addresses use free email providers.
- 4Pick Calendar Event Sync as the trigger and choose where run reports go.
- 5Test with one real event and review the run report.
Questions about this workflow
Does this determine whether an address is valid?
No. Verify Free Email Account detects whether an address is from a free email provider. It does not replace email validation.
Will it work when an event has no attendees?
There are no attendee addresses to check when the trigger returns no attendees.
