Mailbox.org Business Premium, € 9.00/mo. on Cloud Emails

The Premium business plan targets organisations and demanding teams that treat their hosted mailboxes as long term communication archives and collaboration workspaces. Each user receives 25 GB of mail storage, which comfortably accommodates heavy email traffic and large attachments, and additional capacity can be booked in small increments if particular accounts grow even larger. On top of this, the plan includes 50 GB of Drive space per user, providing room for shared file repositories, project folders and personal documents hosted in the same environment as email and calendars. The Premium tier unlocks the full collaboration feature set with online office editing, tasks, notes, chat and high quality video meetings, making it well suited for remote teams and organisations that want to replace a patchwork of different cloud tools with a single, tightly integrated platform.
Premium for business is priced at 9 EUR per user and month net, with VAT added according to the customer’s location. Mailboxes can use custom domains and extensive alias pools, which is particularly helpful when separating internal and external communication or mapping multiple brands to one central infrastructure. Combined with the higher Gold or Platinum service packages, customers benefit from prioritised ticket handling, scheduled onboarding assistance, direct phone contact and an emergency hotline that can be reached around the clock for critical incidents. This plan is therefore aimed at companies that view email as a mission critical core service, require generous storage and collaboration features for many employees and want professional support options that scale with their business.

Across all mailbox.org plans, the service positions itself as a privacy-first alternative to ad-financed mail platforms. Every account uses ad-free webmail and standard protocols such as IMAP, POP3 and SMTP with TLS-only transport, while powerful spam and virus filters, disposable addresses and fine-grained blacklists reduce unwanted mail. Data is stored exclusively in redundant data centres in Berlin, Germany, operating under strict German data protection rules and the EU GDPR, and advanced security features like PGP and S/MIME integration, two-factor authentication, one-time passwords and an own key server are available to all users. Beyond email, the platform offers calendars, contacts, tasks, cloud drive storage, online document editing, polls, chat and video conferences so that teams and families can collaborate without depending on big advertising-driven ecosystems. Billing works on a prepaid model: you top up credit via bank transfer, SEPA direct debit, credit card, PayPal or various cash-based methods and can move between price plans without long-term contracts or rigid terms, while business customers gain a dedicated admin console and optional API for automation. A 30-day free trial allows new users to test features in depth and migrate existing mail, calendars, contacts and files with the assisted relocation service before committing long term.
