Email Storage
Email storage is the server space that an email account uses to store emails. All incoming and sent emails are stored here until they are deleted. Unlike the web space of a hosting plan, the email storage only stores email data, including attachments, and all data you manage with Webmail, the email web application of IONOS, including calendar entries, notes, and contacts that you have entered in Webmail.
Every email account has some amount of assigned email storage available. The size of the email storage varies and can be increased for a fee if required depending on the selected product.
