Diobox RSVP forms are built for private, invite-only events and work together with your email invitations. Each invited guest receives a unique RSVP link that cannot be transferred, which keeps your event secure and exclusive.
The Guest Experience
Each guest opens the RSVP form from the unique link in their invitation and confirms or declines. Because the link belongs to one guest, only that guest can respond, even if the link is forwarded.

This document provides detailed instructions on how to:
Create a New RSVP Form
Go to the Forms page and click + Form in the upper-right corner.
Choose RSVP from the list.
Set Form Availability & Attributes
When you create a form, the New Form window opens with the following attributes. You can change them later by editing the form's attributes.
Name and Description: The form name and an optional description. Both appear on the Event Portal and on the guest's receipt.
Language: Shows the Language Template the form uses, which is the event's default unless you change it. Click Change Language to use a different template for this form, for example to offer the same event in two languages. Setting a form to a language different from the event's default requires a Corporate plan or higher.
Closing Time: The form closes on this date and time. Clear the date if you don't want the form to close, even after your event ends.
Quantity: The maximum number of submissions. The form closes once this number is reached. Leave it as Unlimited for no limit.
Submission Message: An optional message shown on the confirmation page after the form is submitted, such as a thank-you note or next steps.
Email Confirmation: Use Event Default follows the setting in Portal → Automated Emails, and shows whether it is currently enabled. Select Disable to stop confirmation emails for this form only.
Customizing Your Form
Use the Diobox Form Builder to add custom questions, images and text, and adjust the form to match your event.

Show Additional Registration Fields
RSVP forms mainly ask guests to accept or decline, but you can also collect more details, such as company and job title.
To add fields, click the top of the form in the Form Builder and select the fields you want from the right sidebar.
Allow Guests to Manage Their Plus-Ones
You can let guests register their own plus-ones. This is especially useful for private events where registration is not open to the public.
Plus-one management works in two ways:
New Plus-Ones: Guests without plus-ones can add new ones, up to a limit you set.
Editing Existing Plus-Ones: Guests who already have plus-ones can edit their details. This is helpful if you assign plus-ones to specific guests before sending invitations.
To turn this on, open the RSVP form in the Form Builder and enable Allow Guests to Manage Their Plus-Ones. You can also set the maximum number of plus-ones per guest and choose which fields are required, so you stay in control of your total headcount.
