The team is very responsive, they are always willing to help out with any questions I have or concerns that come up during my project.
They also do an excellent job at keeping me updated throughout every step in our process so there aren't surprises along the way! Nothing really - just make sure you get everything set before hand because it can be difficult getting things back into place if something goes wrong down the road (which happens sometimes). We've been working together since early 2018 but haven't had much contact other than emails until recently when we started using them again as part of this new campaign launch.
