PromoterLink and Embeddable Survey
Use custom code to insert your survey where you need it. You can choose from a survey link or a code snippet. These can be found in the "Embed Codes" section of your campaign.
Use a custom link to direct your users to take an NPS or CES survey.
When users click on your campaign link, they'll be taken to a single page that has the two NPS or CES questions. The minimum requirement needed is to click on a score, and provide an email address.
iframe Code Snippet
Use the code snippet to embed the campaign's survey directly into any webpage, or medium that accepts HTML. This also has a minimum requirement of a score being clicked, and an email provided. The survey will look the same as the PromoterLink above.
