By default, Calendly asks each invitee for their name and email address when they schedule with you. These are always required so event details can be shared automatically. You can also create additional questions to collect more information. Invitee answers to questions will be saved to the event details on your dashboard and added to notifications by default.
Name and email address
Once an invitee schedules, their name and email address will be automatically populated when they book again. You can disable the autofill setting from the Invitee Questions section within each event type. Hover over the fields to edit the settings, then uncheck the option for Autofill Invitee Name and email from prior bookings option.
For each event type, you can add up to ten additional questions. Each can be marked as required or left as optional for your invitees. Choose the answer type that best suits the information you're collecting.
After choosing their preferred date and time, an invitee can decide to add any additional guest email addresses to be notified about their booking. Guests will be sent a calendar invitation or a copy of the invitee confirmation email, depending on the notifications settings for that event type. View any added guests within a scheduled event's details on your Dashboard.
To enforce only one invitee per event, navigate to the event type you would like to update and expand the Invitee Questions section. Hover over the name and email fields to reveal the option to edit, then uncheck the Allow invitees to add additional guests option.
