Custom fields are used to store information about your subscribers, you can think of these like the columns in a spreadsheet. You can use custom fields to personalise your email campaigns; each custom field has a merge tag that can be used as a placeholder in your emails. To learn more about using merge tags seeĀ Campaign tags and filters
Custom fields also appear on your subscription forms, for more information about subscription forms seeĀ How to add a subscribe or unsubscribe form to your website
To create or edit your custom fields click on Lists, click on the name of your list and then click on Custom Fields.
By default, every list will have the Email Address, First Name and Last Name custom fields created for you automatically. You cannot remove the email field but you can delete or alter the other default fields.
For each field, you can specify the merge tag that will be used in emails, whether the field is required when subscribing to your list, whether the field should be visible on forms and the sort order in which each field should appear.
