Which of these is a placeholder in a document into which variable data is inserted during the process of a mail merge?

A merge field is a placeholder in the main document, such as «FirstName», that is replaced with information from the data source for each recipient. The data source contains the variable information, while the main document holds the text and merge fields. An address block is a ready-made group of merge fields for recipient address details, not the general term for a placeholder.
