Best image sizes for email newsletters

Get your pixels straight

The images in your email newsletters bring life to the stories you share. Whether those stories share events, business updates, or new items for sale, quality images create better emails! Let’s explore recommended image sizes for email newsletters so you can effectively deliver your message.

Images in email newsletters tell the story

There isn’t a prescription to follow for the quantity or types of images to include in your email, so you’ll have to trust your gut —or enlist friends whose guts you trust! Send tests to yourself and look at the mailing in your inbox. Do the images draw your eye to the right spot? Is the email too busy? Too bland? Descriptive? Ask yourself how the email feels. Then tweak your content accordingly.

Generally, with images, it’s better to under-do than overdo.

Image Sizes For Email Newsletters

3 guidelines for effective image formatting in email newsletters

GoDaddy Email Marketing can handle a wide range of image formats and sizes, so these tips really take your readers’ inbox needs into consideration. The main thing to keep in mind: The file size of the image significantly impacts how long it takes for an image to show up in an inbox. If you follow these guidelines, the images will load quickly.

Before we dive in, if you don’t have an image editor you like, try these free online tools: PicMonkey and Aviary. Saving your image via either program should result in an email newsletter friendly image every time.

File Size: Less than 1MB (under 100kb is the ultimate)

Your readers view your email newsletters through all different types of internet connections and speeds. Keeping your file size small helps your emails load quickly in all sorts of environments. Anything too big will take forever to process, and will bog down your email when it is being sent and opened. You want to keep your emails light and easy for people to open!

File Type: .jpg, .png or .gif

Most images that you want to include in your email newsletter already come in one of these formats. Some more advanced image editors may offer more image file options. As long as you stick to the three file types above, your email marketing program will love you and so will your readers  :)

Image width: 590px for a banner image and 530px for a regular email newsletter image

These are the maximum widths an image displays at in your email newsletter. Our team has tested image and email display in many different email clients and inboxes — these sizes help your emails look beautiful everywhere. Most of the time, if you adjust your image dimensions to a 590px (for banners) or 530px width (for everything else), the image file size will take care of itself.

Remember: Sizing an image from large to small is always preferable to stretching a small image to larger dimensions.


Stretching from small to large is how images wind up fuzzy and pixellated. There’s a really useful chapter about image sizes for your email newsletters in our free email marketing guide for small businesses, too. Now that you know the preferred image sizes for email newsletters, get out there and create your next email marketing campaign and reel in those customers!
