Mail Merge allows you to produce many letters or documents, which differ in names and addresses but the main text remains the same. For example, suppose you have a firm and on the firm name want to send Dipawali greetings to hundreds of friends, colleagues and relatives. Then it is not necessary to type a separate letter with his name and address to each of one. You can type the text of greetings only once which will be main letter, and by using the mail merge feature you can take as many copies of the main letter as you want.
