When looking to create a form, you will see the option to add a Smart Field question.

A Smart Field is a form question type that the users can send to a contact.

When the contact completes the form, their contact details will automatically be updated in their contact profile.

The Smart Field will also overwrite the existing contact details, or add them if they do not exist.

When you look at your form, some questions will have a grey icon, and others will have a little blue icon. The image below shows one question with a Smart Field, and one without.

Note: If a user has a primary and a secondary email entered for a client, and the client responds to the form with their secondary email, the secondary email will then become the primary email in their Contact profile.

When editing a question, you can change the Question Type by clicking on the box to the left of check mark.

A drop down menu will appear, allowing you to select the Smart Field option.

From there you can specify the Smart Field you'd like to use.
