An Optimum technician generally sets up your primary email address at the time of modem installation. If you installed your own modem, then you can set up a new primary account email address by visiting the Optimum ID Management Center (link in Resources). Up to four additional email accounts can be added to your Optimum Online account, as Optimum Online Boost, Optimum Online Boost Plus and Optimum Online Ultra accounts support up to 14 additional email addresses. Sign in to your Optimum Online account to access your email on the Web. Tips Warnings Writer Bio
