Thanks lisao!
I have used that feature While that feature works well with straight text and an image or two, it does not allow videos, formatting (bold, italic), and other features that actually we have much need for in our posts (especially the video inclusions, as we have many). So unfortunately the email system creates more back-end work than it simplifies.
I appreciate you mentioning this though.
I am hoping SquareSpace finds a solution soon!
