600 Pixels Wide

If you’re talking about size in terms of dimensions, I will propose 600 pixels wide for a picture featured in a campaign and take up your email’s entire width. I’ve found 600pixels to be excellent in all conditions after years of using Mailchimp and other email marketing tools. Height gives you more options. Because people can scroll, even on smartphones, you can take photos quite tall. If you require a tall image, slicing it into slices/chunks and layering them one on top of the other is a frequent strategy. It will appear as if they are a single image if you don’t leave any margins or spacing. Suppose you were building a tall graphic for an e-commerce store where you showcased product categories, for example. In that case, you might create the image so that you could split it into slices, each slice referring to a different category or promotion. You may even build separate links for each slice pointing to those categories.

72 Pixels Per Inch at Low Resolution

Size the image at 72 pixels per inch. For print, it would need to be around 300 pixels per inch to come out crisp and clear, but on a screen it doesn’t need to be that large. Taking the resolution down makes the file considerably smaller, so it won’t bog down your email marketing platform.

Less Than 600 Pixels Wide

Mailchimp’s email templates are 600 pixels wide, so your pixels maximum should be less than 600 to render correctly. I’d suggest 564 pixels for full-width images. You also don’t want your images to be too large to slow loading time for your email recipients. In order to make your email responsive, check out Mailchimp’s website for their recommended widths based on the type of email you’re sending.

No Larger Than 719 Pixels Wide

If you want to make sure people can see your images, you’ll want to make sure they are no larger than 719 pixels wide. This will make sure that people on any device can see them. You’ll also want to make sure your images are no larger than 5 MB so that people don’t see “loading” bars when they open the email. For best results, you’ll want to make sure that your images have an aspect ratio of 9:16 so that they look good when they are displayed in your emails. You’ll also want to make sure you have your images edited and optimized for email so that they download quickly.

557 in Width

For Mailchimp images, resizing photos to a width of 557 and setting “keep proportions” for their heights ensures that your image will format properly across all platforms. Images larger than a width of 557 can displace your newsletter — 557 is the ideal size for all of your Mailchimp email campaigns.

Less Than 1MB Or 72dpi

When using Mailchimp for email campaigns, it is of the utmost importance to be aware of the size limitations of images. In general, the image size should never be over 1MB and a pixel density of 72. However, there are other factors that need to be considered as well.  

One main consideration is the width of the image. You can have a 1MB image, but it can be too wide. Mailchimp will try to autosize the width, but this can lead to major distortion and formatting issues. So it’s best to insert the correct width image from the start. Here’s the breakdown: Full width image – 564px; column section images – 264px; column section images – 164px  These are just basic values. The more complex the campaign, the more considerations will be needed. But, if you stick with 1MB, 72dpi, and the widths above, your campaign should run without issues.

No Larger Than 1200px

Mailchimp images shouldn’t be any larger than 1200px wide, but the height of the image can vary based on your templates, messaging, and goals. This is important for the folks receiving your emails because if your images are larger than 1200px, the email will take longer than it should to load, which could lead to dissatisfied customers or even people choosing to just delete your email rather than wait for the download. This can often be improved by compressing images a bit, though a good rule of thumb is to consistently keep Mailchimp email campaign images 1200px wide or smaller.

Less Than 1MB Without Compression Or Cropping

Keep your images under 1MB as a maximum file size, but don’t distort them through compression or cropping. Sending smaller images in Mailchimp is important to reduce lag and potential data fees for your customers, but don’t just condense or compress your images without a proper assessment. A distorted image will give off a lack of professionality, and it can do more harm than good. For that reason, send images that were initially designed small, instead of artificially compressed or cropped ones.

Ideally 600 X 421 Pixels

600 x 421 is the ideal size for images in Mailchimp email campaigns. Larger images will be automatically resized. Additionally, Mailchimp recommends a resolution of 1200 x 842 pixels to maximize visibility on retina displays. You should also consider any margin styles or padding in the Campaign template before choosing an image. Still, 600 x 421 pixels are the optimal dimensions to fit well with any of Mailchimp’s templates.
