Adding an RSVP button to a Salesforce Marketing Cloud (SFMC) email lets recipients register for your event from your campaign send. Copy the RSVP link from AddEvent and insert it in your SFMC email template.

Step-by-step

1. In your AddEvent dashboard, create your RSVP event and go to Sharing
2. Copy the RSVP link
3. In SFMC Content Builder, open your email template
4. Add a Button block or styled <a href> anchor tag with the AddEvent RSVP URL as the destination
5. Set the button label to "RSVP Now" or "Register"
6. Test with SFMC's preview and send a test to confirm the link works

Personalizing the RSVP experience with AMPscript

If you want to pre-fill attendee information or pass subscriber data to the RSVP page, include it as URL parameters: ` %%=RedirectTo(CONCAT('https://www.addevent.com/event/YOUR-EVENT-ID?email=',emailaddr))=%% ` This passes the subscriber's email address to the RSVP page, reducing the fields they need to fill in.

Journey Builder

In a Journey Builder path, add an Email activity with the RSVP link in the first touchpoint. Add a wait step followed by a decision split based on whether the contact has registered (via a data extension updated by Zapier or the AddEvent API).

Syncing registrations back to Salesforce

Use the AddEvent API or Zapier integration to push new RSVP registrations into a Salesforce data extension or Sales Cloud contact record, triggering downstream automations in your Salesforce instance.
