Apple Mail Preview Tool
See exactly how your email campaigns appear in the default Mail app on iPhone and Mac. Perfect for testing subject line truncation and snippet clarity.
📖 How to Use the Apple Mail Preview Tool
Input Sender Details
Enter the sender name. Apple Mail displays this as the largest text in the iOS list view, making sender reputation critical.
Craft Your Subject
iPhone screens truncate subject lines quickly. We recommend keeping important keywords within the first 35-40 characters.
Optimize the Snippet
The "Snippet" is the text following the subject. In iOS, it typically shows 2 lines, offering significant real estate for conversions.
Check Desktop vs Mobile
Switch to macOS view to see how the subject line becomes bold and the snippet follows. The visual hierarchy changes between devices.
💡 About Apple Mail Previews
Apple Mail remains one of the most popular email clients globally due to its integration with iPhone and Mac. Understanding its unique rendering logic is key for email marketers.
- The Unread Dot: Apple uses a bright blue dot. It is positioned to the left of the content and shifts the entire text block.
- Snippet Length: Unlike Gmail, Apple Mail is generous with snippet text, often showing two full lines on iOS and macOS.
- Desktop Hierarchy: On Mac, the Subject line is bold while the Sender is regular weight. This is the opposite of the iOS mobile layout.
- Font Rendering: Apple uses the system font (San Francisco), which is highly legible even at small sizes, allowing for longer previews than many competitors.
