Manage List and Signup Form Fields

This feature requires Manager user level or higher.

Information about subscribers is stored in list fields and can be viewed in the list and in subscriber profiles. The fields can be edited to meet your needs through our Form Builder or through the list settings in your MailChimp account.

Below, you'll learn about the different fields, how to add and delete fields, and how to add a predefined list field.

List Field Types

There are several field types available to help you collect subscriber data when they sign up or when you import existing data into your list. If you plan to import a list, make sure your data is formatted for our field types.

  • Text
    Subscribers provide typed responses. This field type is good for general questions, but character limits for list fields prevent long responses.
  • Number
    Subscribers provide any number, like age or an ID number. We recommend you use the Zip Code field for zip codes.
  • Radio Buttons
    Subscribers choose only one of a predefined set of options. Use our presets or create your own. This field can be used to create groups.
  • Check Boxes
    Subscribers select one or multiple options to select different interests. This field will always create a group in your list.
  • Drop Down
    Subscribers choose only one of a predefined set of options. Use our presets or create your own. This field can be used to create groups.
  • Date
    Subscribers specify a date, including month, day, and year. This field supports U.S. and international date formats.
  • Birthday
    Subscribers specify a date, including month and day. Choose from Month/Day or Day/Month format.
  • Address
    Subscribers provide their full address, including country.
  • Zip Code
    Subscribers provide 5-digit zip codes. Use an Address or Text field to collect international postal codes.
  • Phone
    Subscribers provide a local or international phone number.
  • Website
    Subscribers provide a full URL. This field type generates the HTML code for a link.
  • Image
    Subscribers provide an image URL. This can be used to display their own image or avatar in your campaigns.
