We use Mailtrain behind SendGrid. SendGrid charges out the ass for keeping contacts and doing newsletters, so we use Mailtrain to manage lists and campaigns. Mailtrain tracks clicks and stuff too, which is all we really need. We've never gotten a positive ROI from emails, but use them as a way to finish off a marketing budget. My only gripe about Mailtrain is its development stack. There was a bug and I wanted to fix it, but it has one of those "magical" type environments where things magically link up and work, which means a ton of investment on my part to figure out what's going on.
