Optimal image size for Klaviyo newsletter

Hello @Sales@AHB,

Thank you for your question.

I recommend following the guidelines outlined in Best Practices for Using Images in Emails.

In short, across the web, using 72dpi resolution is best practice. Try to keep your images to 600px or less in width and less than 2000px in height, in order to balance image quality and loading speeds. In terms of the “why”, I recommend reviewing our article on Optimal Email Template Width.  A 600px width will help optimize emails built with Klaviyo for mobile viewing as well.

Thanks and have a wonderful day.
