That title may be super nerdy but if you're in the business of web development, pay attention, Mandrill is a new service from the folks at Mailchimp that allows apps to send "transactional emails." Even if that phrase means nothing, take a moment to peruse the site - it's gorgeous! Huge images, clear information and responsive scale down. MailChimp is killing it these days and Mandrill is just more evidence of that.
