Adding new fields

If you want to personalise your emails, you will likely want to use additional fields – we call these custom fields. Custom fields are widely used to store information on a subscriber, such as their address, phone number or age.

You can find them by heading to your mailing list and clicking on the Fields tab. The "Add field" button is located on the left side.

When you click on the “Add field” button, you will see a pop-up asking you to provide the following information:

• Label: The field label is a descriptive name, used only within the platform. 

• Type: There are a few types of fields on our platform that can be used for different purposes. You can choose from the following field types:

• Text: Versatile field type that accepts any kind of text. 
• Number: This field type accepts only integer numbers.
• Date: Used to store dates in YYYY-MM-DD format. When importing contacts or adding them via the API, they will need to be in this format. When using forms or landing pages, they will display in the preferred format of the end user.
• Choice (select one): Allows selecting one option from the predefined choices.

• Choice (select many): Allows the selection of more than one option from the predefined choices.

  
  

• Merge tag: This merge tag is a single word, used as an identifier when you need to reference the field. The tag is used for both merge tags and when searching for contact. As a default, the merge tag will be generated based on the Label, but you can modify it to your liking.

  
  
• Default value: The default value is the content used by default if a field is referenced in a campaign but doesn't exist for a contact.

When using Choice fields, you will also be asked to provide the choices that your recipients can select on your sign-up forms, landing pages, and from their Subscriber profile page. You can also add them through an import or via the API:

On Starter plans, you may add up to 7 of your own fields, making the total number of fields stored 10, including email address and the First and Last name. On Pro plans, you can store up to 50 fields per list.

The character limit for every text custom field value is 600.
