Email Marketing Blog
Litmus Blog . We are big fans of Litmus. Besides being a useful tool, it is an indispensable reference. They offer studies on the most used email clients and devices, infographics, layout and design tips,… In addition, in their comments we often find interesting debates, since their readers are a very active community. Campaign Monitor and Mailchimp
Blogs . Despite being a Small/Mid Market ESP, they have a great gmx email list reception from the majority of the public and this is reflected in their blogs, which are very active and widely followed. As they are ESPs, they have data on a large number of emails and they use it to offer very interesting information (opening data, examples of successful campaigns…)

Marketing Sherpa . More than a blog, it is an archive of interesting articles and, above all, interesting case studies.
Email Institute and Campaign Monitor Templates . Two sources of inspiration to dive into before tackling the designs of our emails.
Style Campaign Blog . Anna Yeaman's posts will leave you speechless. She analyses various topics in depth and makes clear and very useful presentations and videos. The agency specialises in making emails adaptable to all devices, so you will find interesting articles on Responsive Email Design.
Email Wizardry . But there are not only corporate blogs. In this case, Australian Nicole Merlin helps us to better understand how to create email layouts and also offers us reflections on the latest trends, design examples and very interesting practical cases.
