I'd like to note an easy-to-use service: non-intrusive design, user-friendly interface, fast search. There are really loads of newsletters from companies around the globe. To gain a quick insight into the technical details you can download newsletter as HTML-file. You can also search for newsletters by name, topic or even hashtag - this is very convenient! When I'm searching for newsletters by subject I have a panel of settings giving me recommendations: what day and what time are the best to mail out this kind of newsletter. In my opinion the service would be an indispensable tool for designers, layout designers and marketing experts.
