Steps of generating business letters using mail merge
Answers
When you have bulk mail to send to people on your mailing list, you can use mail merge to create a batch of addressed envelopes. Each envelope will contain an address in your mailing list. You can also create and print envelopes without using mail merge.

These are the documents involved in creating and printing envelopes using the mail merge process:
Your main document
This document contains text and graphics (a logo or an image, for example) that are identical for each version of the merged envelope. The return address on the envelope is an example of identical content.
Your mailing list
This document contains the addresses to be printed on the envelopes.
When you combine those two documents using the steps below you'll have your addressed envelopes.
Step 1: Set up your mailing list
The mailing list is your data source. It can be an Excel spreadsheet, a directory of Outlook contacts, an Access database, or an Office address list. It contains the records Word pulls information from to build the addresses to be printed on the envelopes.
Tips
If you don’t have a mailing list, you can create one during mail merge. Before you start the mail merge process, collect all of your address lists, and add them to your data source.
If you're using an Excel spreadsheet, make sure the column for ZIP Codes or postal codes is formatted as text so that you don't lose any zeros. For more information see Format mail merge numbers, dates, and other values in Excel
If you want to use your Outlook contacts, make sure Outlook is your default email program.
Step 2: Test your envelope layout
A preliminary step in the mail merge process is to set up the envelope for the merge. It's always a good practice to run a small test batch of envelopes before you do a real mail merge.
Note: If you're comfortable with printing envelopes on your system you can skip to step 3.
In Word, choose File > New > Blank document.
On the Mailings tab, in the Create group, choose Envelopes.

In the Delivery address box, type a sample address to test how an envelope will look when it's printed.

Note: The sample address won't show up in your mail merge.
In the Return address box, type your address.

Choose Options > Envelope Options and do the following:
In the Envelope size drop-down list, choose the size that matches your envelope or choose Custom size.

Note: If you choose Custom size, enter the envelope dimensions in the Width and Height boxes. Choose OK when done.
Under Delivery address and Return address, choose a font and the left and top offset position for each address.
Note: Based on the preview of the envelope layout, make any necessary adjustments to your choices.
On the Printing Options tab, confirm the correct Feed method is selected, load the envelope to match the illustration, and then choose OK.
Note: Your printer sends Word information about which way the envelope should be loaded in the printer. This information appears under Feed method.

Choose Print, and then choose Yes to save the return address as the default address.
Note: If the envelope printed correctly, congratulations, you're ready to go to the next step in the mail merge process. If the envelope didn't print as you expected, go back to step 5 and readjust the envelope layout options and the Form Feed options as necessary.
Step 3: Start the mail merge
On the Mailings tab, in the Start Mail Mergegroup, choose Start Mail Merge > Envelopes.

In the Envelope Options dialog box, set up the envelope by choosing options as in Step 2: Test your envelope layout, and then choose OK.
Note: Word creates a document that’s sized to the envelope dimensions and shows where the return address appears on the envelope.
If you'd like to add a return address, or logo, to your envelope now is a good time to add that.
Choose File > Save, and add a file name.
