If you’re looking for a simple way to send personalized bulk emails through Microsoft Outlook, mail merge is the perfect solution. Whether you’re running an email marketing campaign, sending newsletters, or communicating with clients, mail merge lets you create customized messages for each recipient using Microsoft Word and Excel or Outlook Contacts.
This 2025 step-by-step guide explains how to set up a mail merge in Outlook, link your data source, and send emails without third-party tools.
What Is Mail Merge in Outlook?
Mail merge is a feature that allows users to send personalized email messages to multiple recipients by combining a template (created in Word) with a data source (Excel spreadsheet or Outlook Contacts). Each message is customized automatically and sent through Outlook, making it ideal for business communication, marketing, or event announcements.
Step 1: Create Your Email Template in Microsoft Word
Start by opening a new Word document:
- Write your email content.
- Insert merge fields (placeholders like First Name, Company Name, etc.).
- Go to the Mailings tab.
- Click Start Mail Merge > E-mail Messages to format the document for email.
Merge fields will later be filled with real data from your Excel or Outlook Contacts.
Step 2: Prepare Your Data Source (Excel or Outlook Contacts)
You can use either:
Microsoft Excel:
- Create a spreadsheet with columns for First Name, Email Address, etc.
- Make sure each row represents a unique recipient.
- Save the file in a familiar location.
Outlook Contacts:
- Use your existing contact list.
- Ensure every contact has a valid email and other relevant details.
Step 3: Link the Data Source to Word
To connect your template with the data:
- In Word, go to Mailings > Select Recipients.
- Choose Use an Existing List (for Excel) or Choose from Outlook Contacts.
- Browse and link your spreadsheet or select your Outlook address book.
- Confirm column headers align with your intended merge fields.
Step 4: Insert Merge Fields in Your Message
To customize each email:
- Click Insert Merge Field under the Mailings tab.
- Choose fields like First_Name, Company, or Email.
- Position them in your email body where needed.
Example:
Hi «First_Name», we’re excited to share our latest updates with you!
Step 5: Preview and Send Personalized Emails
- Click Preview Results to check your messages.
- Use the navigation arrows to view different recipients’ versions.
- Once ready, click Finish & Merge > Send Email Messages.
- Select the field for the To line (e.g., Email), write a subject line, and choose HTML format for rich formatting.
- Click OK. The emails will be sent via your connected Outlook account.
