Mail merge is a feature in Microsoft Word that allows users to create a batch of personalized documents, such as emails, letters, labels, and envelopes, for multiple recipients. The process involves associating a data source, such as a list, spreadsheet, or database, with the document. Placeholders, called merge fields, are inserted into the document to indicate where information from the data source should be included. When the mail merge is complete, the merge document generates a personalized version of itself for each name in the data source.

Here are the basic steps to perform a mail merge in Microsoft Word:

1. Pick the source of data youll use for the personalized information. Excel spreadsheets and Outlook contact lists are the most common data sources, but any database that you can connect to Word will work.
2. Create a new document or open an existing one in Word.
3. Insert merge fields for the personalized content you want to include.
4. Preview and complete the merge.

Mail merge can be used to create a variety of personalized documents, including:

• Form letters that are personalized to address each recipient by name.
• Mailing labels and envelopes.
• Name tags.

Mail merge is a useful tool for producing multiple documents using information stored in a list, database, or spreadsheet. It saves time and effort by automating the process of creating personalized documents for multiple recipients.
