Don't Waste Your Money
First off, Email Campaigns don't work. They say sent but never actually do send. Their SMTP doesn't link with Exchange Server for O365. The lists for your contacts don't integrate with the campaigns like advertised. Overall the tool is a broken mess that only partially works half of the time.
Lastly, I'll add that they keep releasing other tools and completely ignoring the one's they created before. So if you buy anything from GoZen, be sure to get what you need out of it in the first few months as they will not support things after their next new tool is released.
Their support team is non existent and I would go into more detail about that but AppSumo is trash and won't let me speak about that side of things. You can get the details on a more mature review site.
