Mailercloud was easy to set up and get going. The instructions are clear, and my emails are answered within a day (different timezones). The drag and drop features are easy to use. I would love more interactive features like polls and the ability to ask a question and track the answer in a report. The other thing I think is missing is a more robust unsubscribe page so I can attempt to retain my subscribers by giving them other options to stay in touch. Outside of those, I'm happy with the service.
