Happy user of mailchimp here... I think his points are very valid, and I appreciate his "mailchimp might be perfect for you" comment. As someone who went from doing it in-house to Mailchimp, I'll offer some advice: Try an email marketer first, and only bring it in-house if you find that the marketer can't do what you want or is too restrictive. There are an infinite number of things to spend your time on, and sending emails (and having them look good, arrive, get stats, etc) is a huuuuge time sink. If mass emails are not the core of your business then you should be outsourcing it. Build your core, buy the rest.
