Tall images will be cropped in Outlook.
Outlook truncates the upper portion of all images higher than 1728px from the top-down. So, if your image is 250px longer than the 1728px limit, 250px will get cropped off the top. We’ve also seen Outlook re-scale an image so that its max height is 1728px. We suggest that you crop your images and stack them on top of each other.
Images with dimensions defined in HTML may render incorrectly.
Stretched images (e.g., bars, borders, gradients, etc.) may not render correctly. All graphics should have their correct dimensions in the file properties. Do not rely on HTML-defined dimensions for images that are critical to the email’s layout.
Animated GIFs aren’t supported by Outlook.
Outlook does not support animated GIFs, instead it only shows the first slide of your animation so make sure the most important call to action is on that slide.
Whether you’re an e-commerce business directly generating sales from email sends or a B2B company sending a dedicated marketing offer to increase lead flow, mobile-friendly emails can benefit your bottom line.
Now I’m not going to lie, optimizing for email can take some time. But investing just a little more time when preparing your mobile campaigns can go a long way in benefiting your business.

Beat the competition with mobile optimized emails.
Despite rising consumption of email on mobile devices, many businesses refuse to address this shift. The technical and expertise changes needed to become an early adopter prevents marketers from investing in a mobile email strategy. Don’t let that be you! Mobile phone owners aren’t starring emails on their phone to be read later. Once they read it once on their phone, they’re done.
You can either be another unoptimized sender, or you can get on the mobile trend before the competition does and start winning deals faster through mobile.
