The best thing about this software for me was that it can be used to send messages through email, text etc as well which helps in sending bulk emails without any hassle of downloading multiple softwares or plugins. I think one should not have more than two accounts active at a time because if you do then there will always some problem with your account like - "Your message cannot be sent" due to low bandwidth." It would help alot if they could make an option where we don't need to change our flowwright password frequently so that's also something i dislike from them but other wise its pretty good product. We use it mainly to send mails via smtp servers to customers who are using gmail/hotmail.
