Requirements from Constant Contact:
Image Size
“Image Size” refers to the dimensions of your image – the image height and width. Constant Contact compresses any image that is over 800 pixels wide, and the image’s height is reduced proportionally. This causes the image to lose quality – leading to grainy, fuzzy, or blurry images. If an image’s height is greater than its width, then it will be compressed to 1278 pixels.
Most Constant Contact templates are about 600 pixels wide, so we recommend keeping the width of your images to no more than 600-650 pixels. Keep in mind that the 600 pixel recommendation is for an image that spans the width of the email. Check out the table below for recommendations on sizing images for a multi-column layout.
What is the recommended image size for my image?
|
Height |
Width |
Header Image |
- Less than 200 pixels will fully display in email preview panes.
|
- 600 pixels
- Smaller widths will stretch your image to fit the header and larger widths will stretch your email header and distort your email.

*There usually isn’t an ideal height because each block will adjust to fit the image’s height. However, keep in mind that very large images may cause scrolling and some clients, like Outlook, may crop images that are more than 1728 pixels in height.

Resolution
“Resolution” refers to the number of pixels in an image. When you create an image, certain image editing programs allow you to set the resolution.
What is the recommended resolution for my image?
Whenever possible, we recommend that you save the original design file with a resolution of 72PPI (pixels per inch). This will minimize image compression when you bring the image into the Constant Contact Library.
Image size for the web is described in pixels, while images for print media are designed in dots per inch (DPI). Check your computer’s DPI settings, as they can cause image distortion when viewing in certain desktop clients.
File Size
While “Image Size” is the height and width of the image, “File Size” is the amount of storage space your image will occupy. Factors like image size and compression will contribute to the file size of your image.
What is the recommended file size for my image?
Constant Contact won’t allow you to upload a file larger than 5MB. If your file is too large, here are some steps you can take to reduce its size:
- If your image editor has an option to “Save for Web & Devices” or to “Optimize” the image, choose a resolution that shrinks the image’s file size to less than 5MB.
- Remember to flatten any layers when you save the final image. This will help to reduce the file size.
Keep in mind that larger images may also take longer to load in a subscriber’s inbox. If you are running into problems, try keeping your images under 1MB each.
