Go to Marketing Activities.
Select the app, and click Edit Draft.
In the social app editor, go to App Settings and then Advanced Options.
For After Share, select the behavior you want.
If you choose Email Capture, the request is only displayed if the person has not already provided their information.
If you chose Confirmation Message: Go to Share Flow and then Confirmation Message.
Edit the confirmation message.
If you chose Email Capture (instead of confirmation): Go to Share Flow and then Email Capture.
Choose whether to include a marketing prompt, and whether that checkbox is selected by default (Opt Out) or not (Opt In).
Edit the request for email address and the marketing prompt (if you included it).
