I have been using MailChimp for the past couple years. Always looking at alternatives for both my sites and my clients. Curious to hear from anyone that might have experience with Campaign Monitor and what your thoughts are. (https://www.campaignmonitor.com/) The one thing I like about them is that they are very design focused. Every template they make is responsive and gorgeous to look at it. They have the features I need such as RSS to email, etc.
