A mailbox is also referred to as an email account. This email box collects all emails that the user has sent and received to and from his email address.

Every email box has an email address by default.

To access this mailbox, you need an email address as well as an email program (email client), such as IONOS Webmail, Microsoft Outlook or a smartphone app.

Each email mailbox has a specific amount of storage space where the emails can be stored. How large this storage space is depends on the provider and package - there is no uniform regulation. Sent and received emails are stored there until they are deleted by the user.
