The team at EF is very responsive - they always reply within minutes or hours of my request! I love that we can use it for multiple clients in our agency without having separate accounts/profiles set up (which would be expensive). It's not intuitive when you first start using this tool but if you have someone who knows how things work internally then your experience will improve quickly once everything clicks together nicely :) We're solving problems related around digital marketing campaigns across many different industries so there isn't anything specific which stands out as being great about what eFund has done thus far; however, all aspects were well thought through before implementation took place.
