Image Quality in SquareSpace Email Marketing

I am struggling with the image quality in my email campaigns. I have referred to and followed SquareSpace's recommendations for sizing images in email campaigns, but for some reason, the quality of my images is still greatly reduced. Wondering if this happens to others and if any one has found a work around?

Hi Taylor, did you ever get a solution to this problem.  I've been struggling with it for too long!  Thanks, Caroline 

I'm finding the same issue with images - not what I was expecting from Squarespace! Also frustrating that you can't get a refund on an annual subscription...

I'm sorry, I have not found a solution yet :(

I have the same problem 😞 I tried to reach the customer service, They suggest me different resolutions based on their guides but that doesn't work either... 

The free images available from the system also appears blurry... how frustating :/
