Users need a way to preserve line breaks when performing a mail merge from Word to Outlook, as manual line breaks are being removed during the process.

How to Fix Word Mail Merge Removing Manual Line Breaks in Outlook

Product: Microsoft Word 2019
Device & OS: not provided
Scenario: Executing a mail merge from Microsoft Word to send email messages through Microsoft Outlook.
Observed behavior: Word removes manual line breaks (created with Shift+Enter) during the merge, causing the final email formatting in Outlook to look different from the original document.

Before you start

Before proceeding, enable formatting marks in Word by clicking the Paragraph icon (¶) on the Home tab or pressing Ctrl+Shift+8. This allows you to clearly see where manual line breaks (bent arrows) and standard paragraph breaks (¶) are located in your document.

Solution 1Recommended

Replace Manual Line Breaks with Paragraph Spacing

Use standard paragraph breaks and adjust paragraph spacing to simulate manual line breaks, ensuring better HTML rendering in email clients.

Email clients interpret HTML differently than word processors. When Word converts your document to HTML for Outlook during a mail merge, manual line breaks (Shift+Enter) are often ignored or stripped out. Using standard paragraph breaks (Enter) is a much more reliable method for preserving spacing in emails.

Locate manual line breaks

Open your mail merge document in Word and look for the bent arrow symbols that represent manual line breaks.

Replace with paragraph breaks

Delete each manual line break and press the 'Enter' key to insert a standard paragraph break instead.

Adjust paragraph spacing

Select your text, navigate to the 'Home' tab, click 'Line and Paragraph Spacing', and choose 'Line Spacing Options'. Set 'Before' and 'After' spacing to 0 pt to mimic the tight spacing of a manual line break.

Test the mail merge

Run a test mail merge to your own email address to verify that the spacing now renders correctly in Outlook.

Replace Manual Line Breaks with Paragraph Spacing

Consistent Formatting: Standard paragraph spacing is widely supported across almost all email clients, ensuring your recipients see the formatting exactly as intended.

Solution 2

Send the Merged Document as a PDF

Bypass HTML email rendering issues entirely by attaching the mail merge document as a PDF.

Frequently Asked Questions

Why does Word change my formatting when emailing through Outlook?

When Word sends a document via mail merge to Outlook, it converts the text to HTML. Different email clients use varying HTML rendering engines, which can interpret manual line breaks (Shift+Enter) differently or remove them entirely during the conversion process.

Can I force Word to keep my Shift+Enter line breaks in a mail merge?

Due to built-in HTML conversion limitations in Word 2019, you cannot strictly force it to retain manual line breaks in an HTML email. The most reliable workaround is converting them to standard paragraph breaks (Enter) and adjusting the paragraph spacing.

How do I view manual line breaks in my Word document?

You can view formatting marks by going to the 'Home' tab and clicking the Paragraph icon (¶), or by pressing the keyboard shortcut Ctrl+Shift+8. Manual line breaks appear as bent arrows pointing to the left, while standard paragraph breaks appear as the ¶ symbol.
