Review on Front by Brian Samuel

The interface is easy to navigate and understand. It's very flexible too! I've used it with internal clients as well as external partners. There have been some glitches but they get fixed quickly. I don't think there are any features that I dislike about Front. If you're looking for an integrated way to manage your emails internally or externally then this tool will be perfect for you. We use Front to manage our marketing campaigns (both internal & external) so we can keep track of all related assets such as files, links, etc.
