Instead of struggling to read it, you can increase the type size to make it easier to read. Apple Mac OS X and macOS Mail offer a couple of ways to display an email message in a larger font. How to Display OS X and macOS Mail in a Larger Font You're just a keyboard shortcut away from reading an email in a larger font size in Mac OS X and macOS Mail: Only the message content in the preview pane is enlarged or reduced using this method. The Mail sidebars and toolbar, as well as the header of the email, are unchanged in size. Open the Mail application on your Mac and click an email message to open it in the preview pane, which is the large area where you can see the entire email. Press the keyboard shortcut Command++ (the plus key) to enlarge the contents of the preview pane, including the text of the email. Repeat the keyboard shortcut as many times as you like. Each time, the text gets bigger. To reduce the size of the text, use the keyboard shortcut Command+- (the minus key). The size change using this method (either to enlarge or to reduce) is temporary and not saved. The email returns to its original size when you close it. If you don't like keyboard shortcuts, you can enlarge the text in an email by opening the message and selecting Format in the Mail menu bar, followed by Style and then Bigger. This change is also temporary. You can also change the default font used in Apple Mail.
