Why use PDF for mail merge output?

PDF is a world-acclaimed file format that was created by Adobe Systems back in 1993 and is now an open standard. There are many reasons why you may consider using this format to create customized documents in a mail merge:

  • Universal compatibility: A PDF document can be opened on virtually any device, and works with all operating systems.
  • Consistent formatting: Unlike other formats, PDFs maintain their layout, fonts, and images regardless of the software or device used to view them.
  • Print-ready: PDFs are designed to be print-friendly, preserving the quality and layout of your documents when printed.
  • Security features: PDFs provide robust security options, like password protection and encryption, making them ideal for sharing sensitive information.
  • Compact file size: PDFs often have smaller file sizes compared to other formats, making them easier to send and store.
  • Digital signatures: Most PDF tools support digital signatures, adding an extra layer of authenticity and security to your documents.
  • Accessibility: Modern PDFs can be made accessible to people with disabilities, supporting screen readers and other assistive technologies.

For all these reasons (and more), PDFs have become a standard in business communications and can be used in a mail merge to create all kinds of personalized documents, such as invoices, contracts, or certificates.

How to create mass personalized PDF documents?

Let’s start by creating your PDF documents. In this section, we’ll show you how to generate individual PDF files in bulk. To do so, we’ll use Microsoft Word’s built-in mail merge feature. No technical skills required :)

1. Prepare your data source

Create a new spreadsheet in Microsoft Excel. Add a new column for each piece of information you want to include in your PDF mail merge.

Then give headers to your columns. Make sure to choose descriptive names (e.g., Name, Email, Company).

Prepare a data source for your mail merge

Fill the spreadsheet with your recipients’ data. Each row of the spreadsheet represents one recipient.

Make sure that your data is up-to-date. Then, once you’re done, save your Excel document as a .CSV or a .XLS file.

2. Set up your Word document

Open Microsoft Word and create a new document. Craft your template with placeholders for personalized information.

Add some formatting if necessary. Then go to File > Mailings > Select recipients. From there, click Use an existing list and select your Excel spreadsheet to link it with your Word document.

To customize your template document, click Insert Merge Field and select a variable from your spreadsheet.

3. Merge to Adobe PDF

Click Preview Results to make sure that the fields in your mail merge are populating correctly.

Happy with the results? Click Merge to Adobe PDF. Then, under Record range select All, and type the name of your PDF files.

And voilà. Click OK and MS Word will automatically start generating personalized PDF copies of your template.

You can now create hundreds of personalized invoices, invitations, certificates, or any other type of PDF document.

Use this simple technique to streamline your workflow, save hours of work, and make each recipient feel unique.
