Pinpointe supports a single primary user ID (login ID) per customer, called the "Account Owner". By default, your Pinpointe primary user ID (login) will be created using your email address. While multiple people can use the same login, Pinpointe automatically gives you the ability to create five sub-users ("Account Managers"). Each sub-user can have their own login login ID and password. The Account Owner can restrict what features and functionality each sub-user has access to.
Enterprise customers sending more than 250,000 emails per month can get a dedicated instance of Pinpointe, which will allow your company to create multiple user logins with separate access profiles (e.g. restrict some users to only access lists, and restrict others to only be able to send emails, etc) for users and/or departments.
