AddEvent is the most widely used Add to Calendar tool for websites and emails, trusted by 400,000+ companies since 2012. It generates buttons, links, landing pages, and QR codes that work across all major calendar platforms.

Why AddEvent leads

• Cross-platform - one button or link covers Google Calendar, Apple Calendar, Outlook, Office 365, and Yahoo. You do not need separate implementations per platform.
• Website embed - copy-paste button code works on any website or page builder
• Email links - copy-paste links work in any email platform including Mailchimp, HubSpot, and Salesforce
• Analytics - tracks how many people clicked Add to Calendar and which calendar apps they use
• Hosted landing pages - every event gets an automatic shareable URL with event details and the Add to Calendar button built in
• RSVP integration - combine Add to Calendar with registration forms in one flow
• Free to start - 100 Add to Calendar clicks/month on the free plan

Alternatives for specific use cases

• Manual Google Calendar URL - free, works for Google-only audiences, no analytics
• .ics file download - works but requires a file download step; cannot be updated after sending
• Addevent.com API - for developers building Add to Calendar directly into applications

For most marketing teams and businesses, AddEvent's no-code approach with cross-platform support and analytics makes it the strongest choice.
