Hi community,


I am brand new to Klaviyo and creating my first ‘Thank You’ email from the template. When I load my png it is huge and have resized it with unfavourable blurry result. Are there guidelines for optimum IMAGE BANNER height and width for an email?

Also, behind the Banner image (when I add it) there is a block of black which I don’t understand.


Thank you for the help!

Hello @Focus MB,

Thanks for being a member of the Klaviyo Community!

@ashley_mcdermott has as great write up of the recommended image sizes for email in their Community post below:

In it she highlights that the recommended image sizes be:

  • 1mb or smaller
  • PNG file type renders the best 
  • 72dpi image resolution
  • height or width should be no more than 2000px

I would also recommend taking a look at the How to Use Images in Emails and MMS Image and GIF Best Practices articles for more information regarding optimal image sizes for emails.

I hope this helps!
