Hi there,

Double check that you are following the image specs here:

-Image size: Header graphics should be between 600-700 pixels wide, with a proportional height (a general guideline is 100-200 pixels). For images within your mailing's content, we recommend 480 x 480 pixels or smaller. Keep in mind that the larger the image, the greater the chance an email filter or firewall will block the image. (If you have one large image, we recommend building a slice-and-dice, which involves slicing the image into smaller images and coding them together in an HTML table to create a seamless-looking image.) In addition, some servers will reject or filter an email if the content is too image-heavy so make sure to include a balance of text and images. -File type: Save your image as a .jpeg or .gif format before using it in your code.

-Color profile: Your images need to be in RGB color values, as opposed to CMYK color values. CMYK color values are for print and won't render in an online environment.

-DPI: Set your images to maximum quality with a resolution of 72dpi.

-Retina, or high-density, displays produced over the last few years can render images with a much higher pixel count than older displays. This creates an opportunity for much sharper and clearer images displayed in email.  


Luckily, high-density display support for images in email is automatically baked into the Emma application.

To take advantage of Emma’s high-density display support, you’ll need to ensure that your images are uploaded at 1280 pixels wide or larger. This is double the size of the largest photo you would need for a mailing, since a photo stretching the full width of a template would be a maximum of 640 pixels. At the time of send, we’ll do the math for you, downsizing your photo to no less than double the size of the image placeholder you’ve designated. Retina displays take advantage of the extra pixels and display a sharper image as a result, ensuring that all your images will look sharp on high-density displays.

If you’re not able to upload high-res images, that’s okay. Your email will still render fine on all clients, but images may look somewhat “blurry” on high-density displays.

I hope this helps!
