Using Microsoft Mail Merge

Mail merge lets you create a batch of documents that are personalized for each recipient. For example, a form letter might be personalized to address each recipient by name. A data source, like a list, spreadsheet, or database, is associated with the document. Placeholders--called merge fields--tell Word where in the document to include information from the data source.
