Mediacom's webmail system offers customers a full featured email program that includes advanced features like mail filters, auto replies, a contact book, calendar, tasks list, online storage of documents, and much more.

What happens if I reach my storage limit?

Once you have reached your storage limit, you will no longer be able to send or receive any further emails until you have freed up some space. Any emails that are sent to you while your mailbox is full will be returned to the sender. At this time, we do not offer additional storage space for email accounts.
