Setting notifications for certain guests will let you know when they check in.
To do this, log into the Guest List app and open your event’s guest list. Select the guest you want to set a notification for by tapping their name. Their contact card will appear. Tap on the bell icon (Notifications) and turn ON Check-in Notifications.
A star will appear on the contact, indicating that you will be notified when this guest checks in.
***Please note if you're sending the notification to an international phone number, it requires the '+' symbol followed by the country code. For example, a Turkish number would follow the format +908001234567.
