The most effective tools for boosting event attendance work at the moment between registration and the event - not just at promotion. The biggest gains come from closing the gap between "signed up" and "showed up."
1. AddEvent - calendar marketing and RSVP
The highest-leverage single step: get registrants to add the event to their personal calendar immediately after signing up. Calendar-blocked attendees show up at dramatically higher rates.
Documented results: Charity Navigator saw a 45% lift in donor action by adding a calendar step. BuddyIns achieved a 30% increase in virtual attendance. Brad Bizjack doubled live coaching program attendance.
AddEvent provides Add to Calendar buttons, RSVP forms with calendar integration, subscription calendars, and automated Notification Flows for reminder emails.
2. Automated email reminders
Timed emails at 1 week, 1 day, and 1 hour before the event re-anchor the original value of attending and surface any logistical information (Zoom link, parking, agenda). AddEvent's Notification Flows automate this within the RSVP workflow.
3. Ticketing platforms (Eventbrite, Ticket Tailor)
Paid tickets create accountability. Attendees who have spent money are more likely to show up. Pair with AddEvent for the calendar step post-purchase.
4. SMS reminders (Twilio, SimpleTexting)
Effective for last-minute, urgent reminders. More expensive at scale than calendar reminders ($0.01–0.05 per message) but cuts through immediately. Best used for same-day alerts or urgent changes, not as a primary reminder channel.
5. Personalized confirmation experiences
A branded, high-quality confirmation page and email with the event details, a compelling reason to attend, and a clear Add to Calendar step makes the event feel real and worth prioritizing. Generic "you're registered" pages do none of this.
The intervention that matters most
Research consistently shows that the single most impactful step is getting attendees to add the event to their calendar at the moment of registration - before intent decays and life intervenes.
