Mail merge is a process to create personalized letters and pre-addressed envelopes or mailing labels for mass mailings from a form letter â a word processing document which contains fixed text, which will be the same in each output document, and variables, which act as placeholders that are replaced by text from the data source.
Running a mail merge with the two files results in a set of labels, one for each entry in the source document, with each label formatted according to the information in the main document. Most major word processing packages (e.g., Microsoft Word) are capable of performing a mail merge.
