No matter you are going to invite your guests by RSVP or just let the public to join, the first thing you will have to do is completing the Registration Form Settings so that your registrants will know what information they should provide.
If your event is inviting very important guests and your team is justing asking for "Yes" or "No" for guest's attendance with pre-filled information, we would suggest you sending out the invitations via RSVP.
To send out RSVP emails,
1. Click "Broadcasts" in Menu Bar. Create a new email by clicking "Email" on upper right hand corner
2. Select "RSVP invitation" for Template.
3a. A specific RSVP button with RSVP link will be included in the Template as below:
3b. or add the RSVP link into the email content by using the Merge Tag of RSVP URL
Then guests can click the buttons which direct to the RSVP form.
If your event opens to public registration, we would suggest posting a Public Registration Link on your website or promotion materials.
