The team at remergemedia are always willing to help, they take their time with you when answering questions or making changes but it's never more than what you need from them.
Their support could be better as some times I have received an answer within minutes that was not correct! A little expensive in my opinion compared to other providers out there however this may change over time depending how well we work together moving forward. We use remergemedia primarily because of the expertise they bring to bear using data sources such as Facebook pixel/ad server integration etc., This helps us understand our audience behavior which allows us to make informed decisions about future campaigns.
