How do I send an invitation ICS file that appears as a request on the recipients’ calendar?
Registrants can automatically get sent a meeting invite to be put on their calendar automatically or manually. This helps remind registrants of your event to boost attendance.

BigMarker hosts can add ICS files (learn more here) to their invitation emails to ensure that when someone registers for their event, the event is automatically blocked off on that registrant’s online calendar, no matter which email provider they are using. Now, registrants can automatically get sent a meeting invite to be put on their calendars automatically or manually. This new feature allows for registrants to get periodically reminded of your event to help boost attendance.

These ICS files now are available in two formats: PUBLISH or REQUEST.
When REQUEST is selected, the event is automatically sent to each recipient’s calendar as a tentative meeting. The recipient will need to accept, deny or tentatively accept the meeting, but the meeting will display automatically on their calendar.
When PUBLISH is selected, everyone who receives an event invitation email will also receive a meeting invite for the event. Recipients need to manually accept this meeting request in order to add the event to their calendar.
