Mail merge is a Microsoft Word feature that streamlines the creation of personalized letters, labels, envelopes, emails, and a directory. Since mail merge is not one of the most widely used MS Word features, some users may not know how to perform a mail merge in Word to create letters, labels, and envelopes.

If you want to save time that you spend manually personalizing each letter, label, or other document, mail merge can be useful. Even if you’ve never tried to create a mail merge letter before, the process is pretty simple, and below we’ll walk you through each step.

Microsoft Word has a wizard that will guide you through the process of creating mail merge letters. The wizard will ask you for the letter you want to use and the recipients of the letter, so make sure you have a list of recipients ready to insert. If you don't have one, that's okay, you can always add a list of recipients manually.

Using Explorer, navigate to the worksheet containing the recipient list, select the worksheet, and select Open.
