The customer experience is fantastic! I've spoken personally with each team member which has been great- they are all excited about working together as well.
There is not much that I dislike at this point but if there were one thing it would be easy navigation between campaigns in different stages (like an overview). We have found that campaign deputy's platform allows us to streamline our entire marketing funnel. This includes having the ability to measure ROI, creating better content, improving SEO and increasing social media engagement/referral traffic.
