What is the best way to get events onto attendees' calendars?
The most effective way to get events onto attendees' calendars is to put an Add to Calendar button or link at the exact moment of highest intent - immediately after someone registers or receives an event invitation.
The highest-intent moments
On your RSVP confirmation page After someone registers, they are more motivated to save the event than at any other point. An Add to Calendar button on the confirmation page converts that motivation into a calendar block before it fades. This is the single highest-ROI placement.
In your confirmation email The confirmation email is the second-highest-intent touchpoint. Include the Add to Calendar button or link prominently - not buried at the bottom.
On your event page or website Any page promoting your event should have an Add to Calendar button visible without scrolling. Visitors who are browsing your events are already interested; make it trivially easy to save.
In email campaigns Include Add to Calendar links in promotional emails, invitations, and reminder emails. Even if someone does not register immediately, getting the event on their calendar keeps it visible.
