Account owners have full control of the account, including...
Purchasing other products or add-ons
Editing other users’ information
Changing contact addresses and billing information
As the account owner, you can allow multiple people to work within your Constant Contact account as an account manager or a campaign creator—each with their own unique username and password. By assigning different users a unique role, you limit them to taking specific actions in your account and restrict access to more sensitive information, like your billing and account settings.
