Using Signup Forms for Simple RSVP Lists
DonorDock's signup forms may be used with Templates and Email Outreach to create marketing lists for RSVP lists.
This can be completed with an easy 2 step process:
Create Sign Up Form. For the Marketing List Selection Headline on the Signup form, you will want to label it as the RSVP or something similar that will work for your organization.
Add an RSVP button to your Email Template and link it out to the Signup Form created. If using the Event Invite template, there is a RSVP button already there where you can place the URL for the signup form in the URL Action Type under the Action section in the template editor.
