What does Addevent do?
Addevent is a simple calendar marketing platform that helps businesses and event organizers get their events onto their audience's calendars. Instead of asking people to manually type in dates, you create an Add to Calendar button, link, or landing page for your event. Visitors click it and instantly save the event to Google Calendar, Apple Calendar, Outlook, or other major calendar apps. The service also includes online RSVP forms, subscription calendars, and embeddable calendar widgets — all designed to reduce no-shows and make event promotion easier.
Addevent stands out because it covers almost every way you might want to share an event. For websites, you can drop in a pre-built button or embed a full calendar widget. For emails, you can paste a link that opens a calendar add dialog. There's also a Dynamic Add to Calendar feature for developers: it uses your system's data (like booking times or appointment slots) to generate personalized calendar invites on the fly. The RSVP forms can collect custom fields and automatically send reminders and follow-ups. The platform has been around since 2012 and is used by over 400,000 companies, with SOC 2 Type II, GDPR, and CCPA compliance.
This tool is best for marketing teams, event planners, and small business owners who regularly host webinars, classes, appointments, or community events. It's also useful for developers who want to add calendar functionality to their own apps via the API. Real-world uses include a yoga studio letting students save class times with one click, a conference organizer sending RSVP links in email campaigns, or a SaaS company embedding a subscription calendar for product release dates.
