Use mail merge to create custom letters, invoices, labels and more



The idea of mail merge is simple & powerful. Imagine you handle recruitment at a large company. You just hired 300 analysts for the big data division. The next job – generate employment offer letters for each of them. Of course, you don’t want to type these letters one at a time. You have the details of all the 300 offers (name, email, address, offer code, role, benefit package details and date of joining etc.) in a spreadsheet. You also have a template of the offer letter.

Enter mail merge. This powerful feature combines MS Word documents with (Excel) data to generate all the 300 letters in just few minutes.


You can use mail merge in many similar situations – like generating invoices, address labels, certificates etc.

Read the below tutorial to learn how to set up mail merge in Word.

Tutorial – using mail merge to generate invoices

For this tutorial, let’s pick the example of generating invoices.

Step 1 – Create a workbook with your data

Let’s say your invoice has 11 fields, as shown below.


Create a workbook with 11 columns and load data as shown below.


Step 2 – Create an invoice template in MS Word

Open a new document in MS Word and create a document structure that reflects your invoice. You may download the invoice template for inspiration.

At this stage, our invoice looks like this:


Step 3 – Activate Mail Merge


Go to Mailings ribbon in MS Word and click on “Start mail merge” button. Choose the document type that best describes what you are doing (for invoices, you can choose either letter or normal word document)


This activates mail merge mode on your document.

Step 4 – Load data


Now, we need to load the field data. Click on “Select recipients” and choose “Use an existing list”. This opens File>Open dialog. Navigate to the folder where you saved Excel workbook with invoice data and select the file.

Step 5 – Insert fields at right places

Now that we have a list of fields, load them at necessary location in the invoice template using the “Insert Merge Field” button.

Pro tip: You can use Rules option to set up If then rules based on field values. (for example, if the payment reference # is empty, you can show different text)

At this stage, our invoice looks like this:


Step 6 – Preview & complete mail merge


Using the preview results area, check if everything is ok. Once you are ready, click on “Finish & Merge” to generate individual word documents or emails or prints of the invoices.

Pro tip: If you have a PDF printer, you can use that to generate PDFs for each invoice automatically.

Download Mail Merge tutorial files

There are 2 files in this tutorial – Excel workbook with invoice data & Word document with mail merge setup.

After downloading the files: 

  1. Place them in the same folder.
  2. Open the Word document.
  3. At this point, you should get an error. Click ok.
  4. This will open Data link properties dialog.
  5. Type the full path of the downloaded Excel workbook in the Data source field. Click ok (see image).
  6. This should establish the connection for you.

Mail merge is a very powerful and time saving feature. I use it often when I need to generate a lot of documents in one go.

    I have a monthly report where the wording is the same but the data is different. I have a page for the data and then a page that is set up with the data for that month. The mail merge takes that second page and instantly creates my document. It is so much easier than before hurting my neck looking at two documents and hoping I saw the right line.

  2. Candy says:

    This is super useful, thanks for the tip!

    I was wondering, if we're trying to send all these as email messages, will we be able to set up the Mail Merge to also send out the individualised letter to each individual email address?

    • Candy says:

      Ah, it's ok, I've played with it, and yes, it's possible! This is a wonderful function, wish I knew about this much earlier on.

      • scipion says:

        .. well, and how you do it ? would be useful to share.

        • Candy says:

          You just need an additional column for the email addresses. Thereafter, click on "Finish & Merge", and choose "Send E-mail Messages". Use that column you created for the email addresses, and put it under the "To" field.

    This is very useful to send enquiries / RFQs.
    Thereby people are no more require to maintain a separate table for
    response time analysis/ offer tracking.
    Its awesome... doing two work at one time, RFQ creation plus tracking of the same.
    And the data can now give you a whole new world for analyzing and decision making. Awesome.

  4. scipion says:

    Thanks - very helpful.

    On a similar topic,
    I am trying to find a tutorial or help on how to use mailing from an excel spreadsheet. let's says one pivot table where I can filter on a given criteria with several known values (departments or users for example).
    Then generating an email with a spreadtsheet that contain only data filtered for a given value of the filter.

    If someone can point me to a link where I can find some help that would be great.
