An Optimum technician will usually set up your Optimum Online or Optonline primary email at the time of installation. This is how Optimum communicates important news and account status to you, such as billing information and rate plan offers.
If you did the installation yourself, you can set up a new primary email address for your account via the Optimum ID Management Center. In addition, you can create and add up to four additional email addresses to your Optimum Online account.
You can also create up to 14 additional email addresses for your Optimum Online Ultra, Optimum Online Boost Plus, and Optimum Online Boost accounts. To access your email online, sign in to your Optimum Online account.
