Most people are not reading your entire newsletter.
Instead of designing a newsletter, create a landing page on your website with all the graphics and information.
Your email should have one focus and a link to more information.
Measure the success of your email based on how many people clicked the link for more information.
BONUS - you can now link to your landing page in all your media, creating a consistent message across all the platforms.
