Mail Merge

Mail Merge is one of the most powerful features in Microsoft Word. It allows users to create personalized letters, emails, envelopes, labels and certificates for many recipients automatically by combining a main document with a data source such as an Excel spreadsheet or contact list.

What is Mail Merge?

Mail Merge combines two parts: a Main Document and a Data Source. The main document contains the common content, while the data source stores recipient information such as names, addresses, phone numbers or email addresses. Microsoft Word automatically creates a personalized copy for each recipient.
