Outlook Email Preview Tool
Simulate how your email campaigns appear in Microsoft Outlook. Test subject lines, sender names, and preheaders on desktop and mobile.
📖 How to Use the Outlook Preview Tool
Define Your Sender
Enter the "From" name. In Outlook, sender names are bold for unread messages, making them stand out immediately.
Input Subject Line
Outlook generally shows fewer subject characters on desktop compared to Gmail. Keep it punchy and under 50 characters if possible.
Add Snippet Text
The preheader (snippet) provides a sneak peek. Use our tool to ensure it doesn't get cut off by the subject line on desktop.
Test Device Views
Toggle between Desktop and Mobile. Desktop Outlook uses a stacked list while Mobile focuses on sender prominence.
💡 About Outlook Email Previews
Outlook is a staple in B2B environments. Unlike Gmail's single-line desktop layout, Outlook's "Focused" and "Other" tabs often display emails in a list view that prioritizes the Sender and Subject vertically.
- Desktop Layout: Outlook's standard layout shows the subject on the second line and the snippet on the third line, though this varies by user configuration.
- Character Limits: While subjects can be long, most users only see the first 35-45 characters before truncation on mobile.
- Unread Indicators: Outlook uses a distinctive blue vertical bar on the left to indicate unread messages.
- Flagging: Flags (equivalent to stars) appear on the right and can change the visual weight of the email entry.
- The Snippet: Outlook pulls the first plain text it finds. Using our tool ensures your hidden preheader text looks professional.
