Their support team was very responsive, knowledgeable about their product as well has helpful in solving our issues with it! Nothing at this time but would love to have more flexibility when dealing w/ multiple providers like MailChimp (which we're using now). We use this for sending out monthly newsletters through mailchimpoversly via an autoresponder service called SendPulse. It allows us access all of those emails from one account while also allowing them into sendpulte's platform for analytics & reporting purposes only which helps tremendously by centralizing everything together under 1 roof. The benefit here lies mostly in being able to keep track or reports that are specific just to my list without having separate accounts created each month / year for different lists etc.. I can't think of anything really - so if you were looking specifically then let me know :) This makes keeping tabs easier than before since there used be several websites.
