What exactly is Mail Merge in Word?

The characteristic Mail Merge Word allows you to create a batch of customized documents, all with an identical structure and layout, but with specific dates for each recipient. This means you can generate letters, emails, labels or envelopes where only details such as the name, address, date or any relevant information from a list or database change.

When you do this, Word will use the so-called combined fields (placeholders within the text) that will automatically fill in the corresponding information for each record on the list. This way, you can send the same personalized message to dozens or hundreds of people in a matter of minutes, without losing quality or making copy-paste errors.

When is it useful to use mail merge?

• personalized letters for clients, students or employees.
• Printed envelopes with the exact details of each recipient.
• Stickers for postal shipments, identifiers or promotional material.
• Personalized emails automatically sent from Word using contact information from a spreadsheet.
• Documents with variable information, such as certificates, invitations or notices, where only some fields change.

Documents and data involved in the combination

In every mail merge, the following usually intervene: three key elements:

• Data origin: This is the file where you store the recipient information: first names, last names, addresses, email addresses, dates, amounts, etc. Generally, an Excel spreadsheet, a Word table, a database, or a contact list is used.
• Model document: This is the template you design in Word, with the format and text you want all the resulting documents to have, but leaving spaces for variable data to be inserted using the combined fields.
• Combined document: This is the final result of the process, a file where each page (or email, label, envelope, etc.) contains the individual data for each record in the data source. You can choose to print, edit, or send it directly.

Combination types and model document

In Word, the mail merge function adapts to different types of model documents, depending on the objective you pursue:

• Letters: When you want to send personalized letters where only a few key details change.
• Clutch: If you are looking to print data directly onto envelopes, avoiding labels.
• Tags: Perfect for printing on sheets of adhesive labels, very useful for postal mailings, product decoration or filing.

Although the basic process is the same, some steps or fields may vary slightly depending on the template document chosen.

Step by Step: How to Mail Merge in Word

Below you have a organized practical guide to master the entire process:

1. Prepare the data source

Before opening Word, make sure you have your recipient list ready. If you use Excel, put in the first row the headers (First Name, Last Name, Email, etc.) and below each record in its own row. You can add as many columns as you want to incorporate variable data.

Do not forget save and close the Excel file before linking it to Word to avoid import errors. If the list is in Word, use a well-organized table.

2. Create the template document in Word

Open a new document or choose a template and write the base text that all recipients will share. Think about where you'll need to insert variable fields (such as names or amounts) and leave spaces in those places.

Note! You can create very elaborate designs with logos, digital signatures, tables, images, etc. Everything in the template will be repeated exactly in each customized copy.

3. Start the mail merge

On the top ribbon, click the tab Correspondence and look for the option Start mail mergeThere you can choose between letters, envelopes, labels, emails, or other types of custom merges depending on the purpose of your mailing.

For the less experienced, it is advisable to use the Step-by-step mail merge wizard, available from that same menu, as it will guide you visually and easily through all the necessary steps.

4. Link the document to the data source

Click on Select recipients and choose the option Use an existing list If you're starting from an Excel spreadsheet or a pre-made table, navigate to the file and select it. If the file has multiple sheets, select the one with the main list. When you accept, Word will automatically recognize the column headers as fields available for merging.

If you prefer, you can create a new list directly into Word or even import contacts from Outlook.

5. Insert the merge fields

Once the model document and the data source are linked, that's when you insert the combined fields wherever you want the custom data to appear. You can do this from the menu Insert merge field from the Mailings tab. For example, to greet each recipient by name, hover over the text where you want it to appear and select the "Name" field.

• You can insert complete address blocks, automatic greeting lines (“Dear…”), and any other individual fields available in the data source.
• You can customize the text, formats, and order of fields to create a presentation that's exactly how you need it.

6. Customize the format of the merge fields

Many people are unaware that combined fields can formatted to display data such as dates, amounts, or numbers in a specific format. If, for example, when displaying a date you prefer it to be displayed as "20/03/2024" instead of "03/20/2024" (a typical error in English formats), you must edit the field.

To do this you can press Alt + F9 and thus display the code for the fields in the document. In the date field, add the desired format, like this: {MERGEFIELD Fecha_Alta \@ "dd/MM/yyyy"}. Do the same with monetary amounts, adding the format {MERGEFIELD Cuota_Mensual \#.##0,00€}. Press again. Alt + F9 to see the formatted result.

7. Use advanced rules: If…Then…Else

Word allows you to add conditional rules to display one text or another depending on the value of a field. For example, if the "City" field is "Valencia," you can have a different message appear than the other cities. To do this, use the option Rules – If…Then…Else From the Mail ribbon, you can tailor messages, warnings, or personalized instructions to specific recipients, enhancing the professionalism of each message.

8. Visualize the result before finishing

Before generating the final documents, use the results preview to check how each combination looks. You can navigate through the records using the arrows on the ribbon to verify that all the data appears correctly and that the fields are properly connected. This step is highly recommended to avoid last-minute surprises.

9. Finalize and generate the combined documents

When everything is ready, go to the option Finish and combine. Here you decide the fate of the combination:

• Edit individual documentsA new Word file is generated with all the customized records, one per page. You can review and edit it before printing or sending.
• Print documents: The process sends each personalized document directly to the printer, ideal for physical letters or labels.
• Send emails: Automatically sends each personalized document to the email address specified in the corresponding field of the data source, using Outlook as the sender.

Additionally, you can choose whether to use all records, just a current one, or a specific range of recipients.
