When your supporter completes your Registration form, they are then taken to a Confirmation page. This page will thank them and provide action items. It is fully customizable with the settings below.
To start, you need to be in your Registration activity, and then select Confirmation Page from the left categories.
The design of the page is divided into two parts, the Content Section and the Actions Section. The Content section contains the items in the top half of the form and is your acknowledgment that the supporter has completed the registration successfully.
The Actions section gives them something to do, such as go to another page, follow you on various social media and sign up to receive emails or texts from you.
Content Section
The Confirmation screen is where you can immediately thank your supporters for their contributions. The Content section gives you that initial touchpoint and confirms their answers from the registration form have been received.
Title
By default, it will say "Thanks, [first_name]!" in a cursive font. Like with all of the items on the Confirmation Page, you can hide this element with the Show/Hide switch.
You can also edit the Title. If "Thanks " is too personal, you can change it to "Thank You" or anything else. You could also make it more generic with something like "Thank you for taking our survey!"
The Content can be anything you like, so if you wish to be more formal and say "Thank You" vs. "Thanks" just edit the line. You can also change the color and style (Bold / Italic / Underline) of the font.
It does allow for variables, so the standard collected information on the form will be available in the Variables list. It will not have additional/custom variables you may have added to your form.
Subtitle
The Subtitle refers to the automated confirmation message about completing the form.
If you are using a Non-payment registration form (no ask for donations) then it will say "Thanks for your support! Your information has been saved."
If you are using a Payment version of the Registration form it will show that the credit card has been billed. This will automatically show the last four digits of the credit card and the amount that is billed.
There is nothing editable on the Subtitle other than to Show or Hide this element.
Thank You Image
The Thank You Image gives a face to your thank you. You can let the sponsor know with an image of your thanks for their support. If you prefer not to use an image, you can use the Show/Hide switch to disable it.
If you edit the image, you can click on Update and upload your own image, then Save it.
Message
The Message Element is a standard Text Element, which means you can format it with the rich text editor to intent, make things bold, italic, change the font size, type color, etc.
You may want to reword this to better represent the registration.
You can also click Personalize to add extra information to your content from the standard fields in your forms.
At this time, added form element items are not available in personalized messages on the Confirmation page.
Actions Section
Just because this is a Confirmation page of what your supporters have entered on the form, doesn't mean you can't provide them with action items. The Action section gives you four different options for them to complete.
Primary Action Button
After your supporters completes their registration, you may want to send them to your organization's web page or an Event Page for your Event. The Primary Action button allows this functionality by providing a personalized button (up to 20 characters) and the link to the new webpage.
If you use a Primary Action Button without a Secondary Action Button, the button will expand to the width of the confirmation page. If you use both, they will be side by side.
Secondary Action Button
Do you want to give your supports a choice of action? Then add a Secondary Action Button. The Primary Action Button will fill the button with the Activity's main color, where the Secondary Action Button will use the color to outline a white button with the color. 
If you use a Secondary Action Button without a Primary Action Button, the button will expand to the width of the confirmation page. If you use both, they will be side by side.
Follow on Social Media
Provide ways to follow you on your preferred Social Media with the Follow on Social Media options. You have the choice to show links to your Facebook, Instagram, Twitter and YouTube channels.
You can enter the address here manually, or add them in the Shared Settings under Account Settings so they will populate to all your Confirmation pages.
If you don't have a presence on one (or more) of these Social Media channels, you can click on the Edit button and turn off any you do not use.
Mailing List Subscription
Depending on how your supporters reached your form, you may or may not have collected their mobile number or email address, and if you leave those as optional entries on the form (not generally recommended!), you may not have those contact points available. By enabling the Mailing List Subscription feature, you can not only make sure to collect either your supporter's Mobile number or Email, but you will have them explicitly opt-in to receive messages from you.
