There's a lot of really really awesome things. I would say the team is just very open for us. Testing things out - different segments, different copy and they turn around time is just very, very quick which I really, really appreciate and that's been consistent since day one.

Sending a few emails here and there is easy -- sending at a consistently high volume and having them delivered every time is really really hard. Senders handles that for us in spades.
