Merge fields are surrounded by chevrons (<< >>).
After you connect to the recipient list, you can specify the information that you want to include in the mail merge by using fields.
A field is a set of codes that instructs Word to insert information into a document automatically. Informally, you can think of fields as placeholders.
In a mass mailing, the fields you use are called merge fields, and they are the placeholders for the unique information that comes directly from a recipient list. For example, in the illustration, merge fields have been added for information stored in the Address and Name columns of a recipient list.
