Manage Audience and Signup Form Fields

Information about contacts is stored in audience fields and can be seen in the contact table and profile pages. Edit the fields to meet your needs through our form builder or through the audience settings in your Mailchimp account.

In this article, you'll learn about the different fields, how to add and delete fields, and how to add a predefined audience field.

Audience field types

There are several field types available to help you collect data when an email or SMS contact subscribes, or when you import existing data into your audience. If you plan to import contacts, make sure your data is formatted for our field types. Before you can import SMS contacts to your Mailchimp audience, you need to submit an application and be approved.

• Text
  Contacts provide typed responses. This field type is good for general questions, but character limits for audience fields prevent long responses. By default, new audiences include text fields to collect first and last names.
• Number
  Contacts provide any number, like age or an ID number. We recommend you use the Zip Code field for zip codes.
• Radio Buttons
  Contacts choose only one of a predefined set of options. Use our predefined options or create your own. This field can be used to create groups.
• Check Boxes
  Contacts select one or multiple options to select different interests. This field will always create a group in your audience.
• Drop Down
  Contacts choose only one of a predefined set of options. Use our predefined options or create your own. This field can be used to create groups. There's no limit to the amount of answers in drop-down or multiple choice fields, with one exception. Checkbox fields function as groups, and there's a sixty group limit for each audience.
• Date
  Contacts specify a date, including month, day, and year. This field supports U.S. and international date formats.
• Birthday
  Contacts specify a date, including month and day. Choose from Month/Day or Day/Month format.
• Address
  Contacts provide their full address, including country. When you create a new audience, this field is included by default, but hidden from signup forms.
• Zip Code
  Contacts provide 5-digit zip codes. Use an Address or Text field to collect international postal codes.
• Phone
  Contacts provide a local or international phone number. When you create a new audience, this field is included by default, but hidden from signup forms.
• Website
  Contacts provide a full URL. This field type generates the HTML code for a link. This field type is compatible with a full website URL only, and it can't be hyperlinked.
• Image
  Contacts provide an image URL. This can be used to display their own image or avatar in your emails.
• Language
  This field is included in your audience after you enable auto-translate for your signup form. We use it to keep track of your contacts' language preferences.

About the age verification field

Note: This field will only appear if you have an SMS age-gated program enabled. The Age Verification field confirms that a contact meets the minimum age required for your SMS program. It's different from the Birthday merge field, and you'll need it to run age-gated SMS campaigns that include restricted content like alcohol. Here's how the two fields compare.

Limits for audience fields

• Audience field values are limited to a maximum of 255 bytes of information. In many alphabets, this is equal to 255 characters. However, some alphabets or symbolic characters, like stars, use more than one byte of information per character.
• Labels for form fields are limited to 50 bytes (usually about 50 characters).
• After you add a field, the field type can't be changed. If you chose the wrong field type, delete the field and add a new field with the correct field type.
• Audiences are limited to a maximum of 30 data fields for each contact. If you want more than 30 fields of information about your contacts, use groups to help consolidate audience fields, or use tags instead.
• Mailchimp accounts on a Premium plan can map up to 80 fields.
