Mail merge is used to create multiple documents at once. These documents have identical layout, formatting text, and graphics. Only specific sections of each document varies and is personalized.
With the mail merge process, your organization can create a batch of personalized letters or emails to send to your professional contacts. Each letter or email can include both standard and custom content. You can choose, for example, to greet each recipient by their first name, use their mailing address, or add unique information like a membership number. All the information you use to customize the letter or email is taken from entries in your data source, which can be a mailing list.
With the combination of your letter or email and a mailing list, you can create a mail merge document that sends out bulk mail to specific people or to all people on your mailing list. You also can create and print mailing labels and envelopes by using mail merge.
