Free webmail with famously generous storage and, for many people, twenty years of inbox history, which is exactly why leaving feels hard. The ad-free Mail Plus upgrade costs 5.49 euros a month in the EU. Yahoo has been controlled since 2021 by Apollo Global Management, a New York private equity firm, and the free tier is funded by advertising built around what lands in your inbox.

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:

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.
Why choose GMX over Yahoo! Mail?
The decisive argument is data jurisdiction. Yahoo! Mail is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
GMX removes that overhead. As a Germany-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
