Mail merge


Mail merge consists of combining mail and letters and pre-addressed envelopes or mailing labels for mass mailings from a form letter.
This feature is usually employed in a word processing document which contains fixed text and variables.
Some word processors can insert content from a database, spreadsheet, or table into text documents.
It is a powerful tool for writing a personalized letter or e-mail to many people at the same time. It imports data from another source such as a spreadsheet and then uses that to replace placeholders throughout the message with the relevant information for each individual that is being messaged.

History

Mail merge dates back to early word processors on personal computers, circa 1980. WordStar was perhaps the earliest to provide this, originally via an ancillary program called Mail merge. WordPerfect also offered this capacity for CP/M and MS-DOS systems; Microsoft Word added it later on,
as did Multimate.
With the arrival of Windows 3.0 and subsequently 3.1, mail merge took a step forward.

Advanced features

Money can be saved by pre-sorting on zip code and grouping by postal-discount requirements.
A paperless approach is to use mail merge to format email.
Going beyond words, in 2018 The New York Times detailed a further instance of "mass customization" - personalized videos.

Overview

The data source is typically a spreadsheet or a database which has a field or column for each variable in the template. When the mail merge process is run, the word processing system creates an output document for each row in the database, using the fixed text exactly as it appears.
The mail merging process generally requires the following steps:
  1. Creating a Main Document and the Template.
  2. Creating a Data Source.
  3. Defining the Merge Fields in the main document.
  4. Merging the Data with the main document.
  5. Saving/Exporting.
A common usage is for creating "personalized" letters, where a template is created, with a field for "Given Name", for example. The templated letter says "Dear ", and when executed, the mail merge creates a letter for each record in the database, so it appears the letter is more personal. It is often used for variable data printing. It can also be used to create address labels from a customer relationship management database, or for mass emails with pertinent information in them, perhaps a username and password.
