Although Pixed has closed, I have a live demo of the site available online.
Pixed was the premium newsletter for educators. It covered a classroom technology topic in-depth bi-weekly. The sample issue is still available and covers podcasting in the classroom.
Slices was a free bi-weekly newsletter with a cool tech resource in each issue.
The Pixed web site told prospective subscribers what they could expect from each newsletter and captured sign-ups.
Design of both the web site and the newsletter were made to be clean, beautiful, and responsive.
