How Freenet uses CorsProxy.io to deliver news content in their Webmail
Freenet, one of Germany’s largest email and telecommunications providers, integrates CorsProxy.io into their webmail dashboard to deliver news content to millions of users. By proxying external news APIs, Freenet Mail provides users with up-to-date headlines directly within their inbox interface.
About Freenet
Freenet AG (freenet.de) is a major German telecommunications company offering email, mobile, internet, and digital lifestyle services. Their free email service, Freenet Mail, is one of the most popular webmail providers in Germany, serving millions of active users daily.
The Freenet Mail interface combines traditional email functionality with integrated news feeds, weather updates, and other content widgets that enhance the user experience.
The Technical Challenge
Webmail applications that display external content face CORS restrictions when fetching data from third-party news APIs. Without a proxy solution, browsers block these cross-origin requests, preventing the news widgets from loading properly.
Freenet needed a reliable, high-performance proxy service that could handle millions of requests from their predominantly German user base while maintaining fast response times across their webmail platform.
Monthly Traffic Overview
Freenet generates approximately 8 million requests per month through CorsProxy.io, with traffic patterns reflecting the email usage habits of German users.
| Metric | Monthly Value |
|---|---|
| Total Requests | ~8,400,000 |
| Desktop Requests | ~6,450,000 |
| Mobile Requests | ~1,870,000 |
| Tablet Requests | ~57,000 |
The heavy desktop usage (77%) reflects the traditional nature of email checking behavior, particularly among Freenet’s core German user demographic.
Geographic Distribution
