Every email client displays emails differently. Using Inbox Preview helps you see potential design issues across the most commonly used email clients so you can make the necessary edits to your content.
Some email clients clip or distort your email message if it exceeds a certain size. Email recipients scan emails quickly to see if the content is interesting before moving on, so the more they have to scroll, the less interested they become. If the bottom of the email gets cut off in several previews, it's best to shorten your message.
Make sure your main call-to-action link or button is clearly visible in each preview so that your contacts see it at first glance. Having a single call-to-action helps keep your email short, too!
Depending on the email client and its image settings, some recipients may not see the images in your email. For example, Comcast doesn't display images, and Outlook hides images until the recipient grants permission to view them. To make sure your message still works without images, each desktop option in Inbox Preview has a toggle switch so you can view what your email looks like with images and when they are blocked. Make sure to add a detailed image description to each image in your template so your contacts know what they're missing when your images don't display!
Not all email clients support the same fonts. When a font isn't supported, it's swapped for a supported one, which can change the branding and style of your email. If your fonts look different or odd, check your template in the editor to make sure you're using a web-safe font. If you chose a font from the "Other" category, consider changing it to one of the first nine fonts in the list to avoid display issues.


Mobile devices can be set to "Dark Mode" so screens aren't as bright in low-light environments, but each email operating system handles colors and contrast differently, which can make your email look very different from how you intended. This includes inverted colors, poor contrast that makes elements of your email invisible, and image distortion.
