It's easy-to use, it works very well for me so far! I have no complaints about this plugin at all (yet). The support team has been extremely helpful in getting my site back up & running after an incident where some of our emails were accidentally deleted from CF7 - which was quite traumatic given that we do send out over 50k per month via email marketing campaigns alone!! So they came through like pros with fast response times AND great customer service skills aswell. Nothing really comes close when talking business/email software but these guys are top class :D.
