This is a great newsletter! Here are a couple of recommendations:
The campaign is a little long. If your audience is expecting this, then that is great. If they might not be, you could use a link in the longer article and either link to the article hosted on your site/blog (if it is there) or host the article as a PDF in your library and link to "Read More."
Since your campaign is a screenshot, I cannot see what links are added. If your images are not links, I would recommend making them links to relevant information/product listings on your site.
