What is the difference between an Admin and a Manager?

You can delegate access to other members on your team. You can designate them to be either an Admin or a Manager:

• Admin - full access to your account, including billing, account settings, and delegating other team members as Admins or Managers.
• Manager - full posting abilities, can manage your team (but not delegate other Admins or Managers), can't access billing and other account settings.
