The banner image is the graphic that goes right at the top of your email campaign. It's your reader's first impression, so you want your banner image to fit your company brand, or your newsletter’s vibe. You can often grab something from your own archives, but if you don’t have anything readily available there are plenty of free resources out there. If you're starting with a raw image, consider spending some time in your favorite image editor cropping, and adding text. You want your banner image to capture the right tone.
Save your image to 590 pixels wide for the most efficient rendering and loading. The height of the banner is up to you.
We always recommend using a banner images, but if you have a campaign that calls for something a little different, you can skip the banner image by leaving the banner space blank. Your campaign will start at the first module in your layout, and won't display anything for a banner.
