A mail merge is a useful feature in Microsoft Word that allows you to create customized letters, envelopes, labels, and other documents for mass mailings. With mail merge, you can send personalized correspondence to many recipients while only creating the base document once.
What is a Mail Merge?
A mail merge works by combining a main document with a data source that contains a list of recipients. The main document is your letter, envelope, or other template that includes special mail merge fields. When you execute the mail merge, Word generates a copy of the main document for each entry in your recipient list, inserting the field data for each individual recipient.
Here are some examples of what you can do with mail merge:
- Send personalized form letters or emails to customers
- Print addressed envelopes for mass mailings
- Create labels for holiday cards, wedding invitations, product mailings, etc.
- Generate name badges for events
- Produce personalized certificates for students
Mail Merge Process Overview
Here is a high-level overview of the mail merge process in Word:
- Set up your main document. Create a new Word document or use an existing template. Add any text, images, and formatting you want to include. Insert special mail merge fields that will pull data from your recipient list.
- Connect your recipient data source. This can be an Excel spreadsheet, Outlook contacts, another Word document, or other external data file.
- Refine your recipient list. Sort, filter, and make any other changes to select your final list of recipients.
- Preview your merge. Check that your main document combines correctly with your recipient data.
- Complete the merge. Generate the individual, personalized documents for your selected recipients. You can save, print, or send the output.

Mail Merge Tips

Advanced Mail Merge Techniques
Once you master the basics, try some of these more advanced mail merge techniques:
Conditional Content
Use IF fields to check values in your data source and insert text conditionally. For example, you can check the City field to include different event dates for certain locations.
Dynamic Images
Insert images in your main document that change based on values in your recipient data file. For example, show employees their own headshot photo on ID badges.
Data Validation and Hygiene
Use Word’s data mapping feature to clean up your recipient data during the merge process. Standardize formats, remove duplicates, validate entries, and more.
Mail Merge with Outlook
Use your Outlook contacts as the data source for your mail merge. This provides easy access to frequently updated recipient information that you maintain in Outlook.
Mail Merge for Email
Use mail merge to generate individual email draft messages rather than printed letters or documents. Take advantage of Word’s tight integration with Outlook for quick email merges.
Mail Merge with Fill-in Forms
Rather than inserting merge fields into a letter, have recipients fill in their own information using easy fillable form fields you create with content controls.
Troubleshooting Mail Merge Issues
If you encounter issues with your mail merge, here are some common troubleshooting tips:
- Verify your data file is organized correctly with one record per row.
- Confirm all merge fields precisely match column headers in your data source.
- Check for blank lines or extra spaces in your data file entries.
- Make sure number, date, and other fields are properly formatted in your data file.
- Try using a new or simplified data source like a blank Word table.
- Disable any plugins or macros that might conflict with the merge.
- Ensure your main document and data file are both closed before starting the merge process.
- Try restarting Word and your computer before running the merge again.
