What is the purpose of using mail merge software?

The purpose of using mail merge software is to produce identical documents that contain variable elements. This process is particularly useful in situations where a single template needs to be customized for multiple recipients, such as in mass mailings, invitations, or personalized letters. By using a database or spreadsheet containing specific information for each individual, mail merge allows users to generate a large number of documents efficiently, ensuring that only certain fields (like names or addresses) change while keeping the rest of the content identical. This functionality enhances productivity and ensures accuracy in personalization, streamlining the process of communication without the need for manual entry for each document.

Other options, such as creating a unique document, editing images, or encrypting files, fall outside the primary purpose of mail merge. Creating one unique document implies a focus on individuality rather than customization across multiple documents, while editing images pertains to graphical modifications rather than text merging. Encrypting sensitive files involves securing data, which again does not relate to the merging of documents or correspondence.
