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.

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.
