If you have questions about anything at any time, we have a support portal that we ask you to submit a support ticket through.  We ask that you use the portal because #1 there is a knowledge base in the portal where as you are typing in your question to submit a ticket, the vast majority of the commonly asked questions are addressed right there so you can get your questions answered immediately and #2 because we service each campaign and client as a team.  There are multiple people involved in successfully launching and optimizing your campaign, so the most efficient way to serve you, is if you have a question, you submit a support ticket and the correct people will be notified to take the appropriate actions necessary.  We manage a substantial number of clients and having the support tickets in a single place helps us to be more efficient in responding to queries quickly.
