I love Send Now, it's a great way to get a whole dashboard into someone's hands without creating a PDF or PPT (and worrying about line breaks, etc.)
However - it looks like CARD DESCRIPTIONS do not appear in the Send Now picture.
I hope that's a small enhancement and easy to do - please consider. Those descriptions can be really crucial to understanding the data and how it's organized.
Side by side here to illustrate - the yellow highlighted text does NOT appear in the email, and this holds true for any card with a description.
