Mailchimp Image Guidelines

Images are an important part of marketing. Even your brand is usually identified by an image. Mailchimp has certain requirements for images that you include in your email campaigns.

You do not need to have your images at exact dimensions before uploading to Mailchimp as Mailchimp templates are responsive and will display your image at the required dimensions (If you have a custom coded template then, depending on how your template is coded, you may need to resize images before uploading to your email campaign).

Here are answers to frequent Mailchimp email campaign image questions.

What is the minimum Mailchimp image width?

Mailchimp provide recommendations for the minimum image width that range from 132px to 564px wide. The width per the Mailchimp recommendations vary depending on which content block is used and the number of columns.
In my experience after working with hundreds of Mailchimp clients, simply make sure that your images are always a minimum of 600px wide. Using the 600px minimum width guideline works well and ensures that your images won’t appear distorted (except if you add an image to a text content block. Tip: don’t add images to a text content block but rather add images to image content blocks).

What are the maximum Mailchimp image widths?

There is no maximum image width requirement in Mailchimp. Years ago there was a need to get your images at the exact dimensions before uploading an image to Mailchimp. Nowadays Mailchimp will advise if your image is too wide and will allow you to reduce the width in Mailchimp.

What are the maximum image heights?

There is no maximum image height requirement. Keep in mind that the greater your image dimensions, the greater your image file-size is likely to be (which results in slow loading images).

What file-types are acceptable in Mailchimp?

Images in JPG/JPEG, GIF and PNG file-types are all suitable for use in email campaigns. Avoid using TIFF, BMP, PDF and other filetypes besides those listed previously. Images must be saved with RGB colour profile or mode before uploading to Mailchimp (most images are saved with the RGB colour profile and your image colours won’t display correctly if saved with the CMYK colour mode).
