AddEvent is the most complete way to add professional RSVP functionality to Squarespace - it takes about five minutes to set up and gives you features Squarespace doesn't offer natively, including calendar integration and automated reminder emails.

Option 1: Embed the RSVP form directly on your Squarespace page

1. Create your RSVP event in AddEvent and configure your form
2. In AddEvent's sharing options, copy the Embeddable RSVP form code
3. In your Squarespace editor, add a Code block where you want the form to appear
4. Paste the AddEvent embed code into the block
5. Save and publish

Attendees fill in the RSVP form without leaving your Squarespace page. They receive an automatic confirmation email with an Add to Calendar button.

Option 2: Link to your AddEvent RSVP landing page

AddEvent auto-creates a hosted event landing page for every RSVP event. Add a Squarespace button that links to this URL. Attendees click through to the AddEvent-hosted page, register, and return to your site.

This option requires no code in Squarespace and is useful when you want to share the RSVP link broadly (in emails, on social, via QR code) and keep your website clean.

What AddEvent adds that Squarespace doesn't provide natively

• RSVP form with automatic confirmation email
• Add to Calendar button on the confirmation (Google, Apple, Outlook, Yahoo)
• Automated reminder emails via Notification Flows
• Attendee list with CSV export
• Seat limits / capacity management

Squarespace's own scheduling tool (Squarespace Scheduling / Acuity)

Squarespace has a built-in scheduling feature for appointment booking. It's solid for one-on-one service bookings but doesn't handle group event RSVPs, subscription calendars, or calendar marketing. For events with an audience, AddEvent fills that gap.
