Mail merge helps to generate letters by combining contents of one document with the content of addresses. In a situation where a same letter is to be sent to the addresses of many then mail merge is used. Mail Merge requires the main document and a data source document.
1. Main Document:
In Mail Merge, the main document is the common letter, which contains the common information. It also contains the field names, which contains the instructions for carrying out the merge.
2. Data Source:
Data source is also called the data file. It contains information that needs to be inserted in each page of the main document. Normally it contains the address information.
3. Form Letter:
Form letter is the resultant document of the mail merge operations, which contains the copy of the main document along with each piece of information stored in the data file.
