How to Preserve Line Breaks in Word Mail Merge Emails on Mac
Question details
The user needs to maintain paragraph and line breaks when sending emails using the mail merge feature in Microsoft Word and Outlook on a Mac.
- Product
- Microsoft Word, Microsoft Outlook
- Device & OS
- macOS
- Scenario
- Sending a bulk email campaign or personalized messages using the Mail Merge feature.
- Observed behavior
- Paragraph breaks disappear in the final sent emails, causing the entire message body to display as a single block of text.
Ensure both Microsoft Word and Microsoft Outlook are updated to their latest versions on your Mac, as older versions may have unresolved HTML rendering bugs.
Set HTML as the Default Message Format
Forcing both Word and Outlook to use HTML formatting prevents plain text conversions that strip away your line breaks.
The most common reason for formatting loss during a mail merge on macOS is a mismatch in email formatting preferences between Word and Outlook.
In Microsoft Word, complete your mail merge setup. Click on 'Finish & Merge' and select 'Merge to E-Mail'.
In the merge dialog box, ensure the message format is explicitly set to 'HTML Message' rather than Plain Text.
Open Microsoft Outlook. Navigate to 'Outlook' > 'Preferences' from the top Mac menu bar, and click on 'Composing'.
Under the Compose messages section, check the box for 'Compose messages in HTML by default'.
Use Web Layout View to Verify Formatting
Checking your document in Web Layout before merging helps identify if the line breaks are properly formatted for an email delivery environment.

Frequently Asked Questions
Why do my line breaks disappear when merging to email?
This usually happens when the email format is accidentally set to Plain Text during the merge process, or if your default email client settings strip HTML formatting. Plain text does not support rich formatting like paragraph spacing.
Does this mail merge issue happen on Windows as well?
While it can happen on Windows if Plain Text is selected, it is more commonly reported on Mac due to how Microsoft Word communicates with the macOS version of Outlook.
How can I test my mail merge without sending it to everyone?
You can test the formatting by filtering your recipient list to only include your own email address. Send a test merge and check how it appears in your inbox before processing the full list.
Can manual line breaks help preserve email formatting?
Yes. Sometimes using manual line breaks (pressing Shift + Enter) instead of standard paragraph breaks (pressing Enter) forces the email client to recognize and preserve the spacing.
