To ensure that your images in email campaigns look their best, the images must be at least 600px wide.
If the PNG, JPG or GIF image you add to a Mailchimp email campaign is less than 600px wide you may notice that the image appears distorted. To stop this unwanted resizing from happening then only add images to Mailchimp campaigns that at at least 600px wide.
- Before adding any image to a Mailchimp campaign, make sure that the image is at least 600px wide.
Note: It isn’t possible to reliably increase the size of an image. If your image is therefore less than 600px wide then choose a new image rather than trying to increase the width of the image.
