Google Calendar has a built-in setting to prevent spam. By default, events are only added to your calendar automatically if you’ve interacted with the sender before. This affects all scheduling tools, including Calendly.
If you're using Calendly and a first-time invitee books with you, they may need to confirm the event before it appears on their calendar. This article shows how to update your Google Calendar settings so events from all senders are added automatically.
Default behavior
If your invitees haven’t interacted with you before, they’ll see a grey banner that says:
Unknown sender: not added to calendar yet
They’ll need to click I know the sender, then respond Yes to the invite for it to appear on their calendar.

To allow all invitations to be added to your Google Calendar:
-

-
Click the gear icon in the top right corner and select Settings.
