Mail Merge in MS Word

Mail Merge is a powerful feature in Microsoft Word that allows users to create multiple personalized documents — such as letters, labels, envelopes, or emails — for many recipients using a single template.
It combines a main document (the template) with a data source (like a list of names and addresses).

Mail Merge is mainly used for:

  • Sending personalized letters to multiple people.
  • Creating address labels for mailing.
  • Sending email newsletters with individual names.
  • Printing certificates, invitations, or bills with unique details.

2. Components of Mail Merge

Mail Merge involves three main parts:

ComponentDescriptionExample
