Both the sports mailbox and Business mailbox are designed for organizations that want to receive digital mail and gather all important documents in one place. Additionally, in both cases, you can add the Kivra Business Plus service to access more features, such as the scanning of physical mail.
The main difference between the two mailboxes is that the sports mailbox cannot receive mail from government agencies, unlike the Business mailbox. Another important difference is how the mailboxes are managed. For a sports mailbox, changes to contact details and mailbox sharing are managed via Idrottsarenan, whereas for a business mailbox, this is handled directly within Kivra.
