You can use the Surveys Editor to create both Surveys and Sign Up Forms. However, there are some key differences between these two data capture techniques.
Surveys are designed for data capture and as such, give you more options on the different formats of question and data that you can collect. They allow for more styling when using them in the Wired Plus landing pages.
Sign up forms are available for a single purpose. They allow you to collect basic information for a subscription. The signup form is usually better to use when embedding on your own website, but this depends on what data you need to collect and which types of question you use.
Access to these tools depends on your account licence. Professional and Enterprise accounts will have access to Surveys and Forms automatically, please speak to your account manager if you have any further queries.
