GMX

GMX offers free German webmail with 65 GB of storage, integrated cloud drive, online office, and PGP-encrypted messaging built directly into the browser client. Part of the United Internet group, GMX carries the "E-Mail made in Germany" seal that guarantees hop-by-hop TLS between participating German providers and domestic-only data storage.

The service combines a classic inbox with Mail Collector for aggregating external accounts, browser extension MailCheck for instant notifications, a 50 MB attachment limit, antivirus and spam filtering, calendar and contacts, and a lightweight online office suite for documents and spreadsheets. Free accounts are ad-supported, while ProMail and TopMail tiers remove ads and add custom domains.

Key features:

• PGP end-to-end encryption available directly in the native webmail.
• 65 GB free storage with built-in cloud drive and online office.
• Mail Collector and MailCheck centralise every inbox into one view.
• Antivirus and spam filtering applied to all incoming traffic automatically.
• Custom domains on ProMail for professional personal addresses.

All GMX infrastructure runs exclusively in Germany, certified under "Internet made in Germany," "E-Mail made in Germany," and "Cloud made in Germany" initiatives. Data handling follows GDPR and the German Federal Data Protection Act (BDSG), and the parent company publishes transparency information on government requests.

With tens of millions of accounts across Europe and the US, GMX suits mainstream users who want a free, full-featured Gmail alternative hosted entirely on German soil.
