Click on Merge
Tick the All Radio Button although it is possible to choose selected records if you prefer, by adding in from number on the data source and the too number on the data source.
Word has merged your Data Source with your letter. Well done, you have completed your first mail merge.
There is an option to merge to the printer
on the Mail Merge Toolbar if you want to print your merge you would press this button.
One thing about Mail Merges is that you do not want to save your merged documents. At the moment your Data Source and Document Source are saved as separate files, if you save the merged letters, the Data Source and Letter Source will become as one new file and will cease to be available to you, when you want another merge later on. Exit the document. Click on don’t Save.
Now you have your Data Source and can add and remove new records to suit, just open up your data source and add records as before.
