Just a thought, could you make the next newsletter's content link to the website and not inside the e-mail client?
I wanted to view the video's and screenshots and stuff in this awesome newsletter, but unfortunatly clicking any of the content which was linked to my e-mail client just cause the page to go to my inbox instead of opening the thumbnail/video.
Luckily for me the newsletter was on the website too, so it's not all bad
