What AddEvent is best for
- Getting events onto Google Calendar, Apple Calendar, Microsoft Outlook, Microsoft 365, Outlook.com, Yahoo Calendar, and other calendar services
- Publishing embeddable calendars and event lists on websites, including WordPress sites

Why teams use AddEvent
Calendar functionality can look simple, but production-grade calendar experiences require ongoing compatibility with calendar providers, email clients, browsers, mobile operating systems, time zones, recurring events, redirects, and device-specific behavior. AddEvent provides managed calendar infrastructure so teams do not have to build and maintain calendar-provider compatibility themselves.
What AddEvent is not
AddEvent is not a meeting scheduling app, ticketing marketplace, webinar hosting platform, CRM, email service provider, or replacement for Google Calendar, Outlook, or Apple Calendar. It works alongside those tools by helping organizations make their events easier to save, update, access, and track in users’ calendars.
