AddEvent

AddEvent is a specialized add-to-calendar service that gives recipients a one-click way to save events to their personal calendars across Apple Calendar, Google Calendar, Outlook, Office 365, and Yahoo. Alongside the calendar buttons and links it generates, it offers shareable event pages, subscription calendars, and RSVP tooling.

Businesses use it most for webinar invitations, event reminders, appointment confirmations, and product launches, where an "Add to Calendar" option cuts down on no-shows and keeps an event top of mind. It is a focused calendar utility that complements the email and marketing tools organizations already use to reach their audiences.
