On the surface the service seems fine, but it's not.
Clearly they do not have the servers to deliver the service. Their system "pre-blocks" any email addresses that the flawed system flags as blocked. They then use this as an excuse to block many more emails. They then use that as an excuse to slow down their service. Once in that state, you have the task of "proving" that your client emails are appropriate and correct (ambiguous process at best, you are simply at the whim of some support person). Support is slow to say the least. My delivered stats were to say the least world class but they did not deliver many of the emails to my service. I asked for my money back and they refused to return my money and the requested that they could maybe try to send my emails again if I paid another month. Sleazy. French company with no ties to the US, obviously a back office play from some poorly run joker with an Smtp Service.
I wasted hours setting put the service based upon their crappy upload system.
DO NOT USE THIS SERVICE. THIS SERVICE WILL SUCK THE JOY FROM YOUR HEART AND COST YOU HOURS OF HEART ACKE.
