Frequently Asked Questions
Why is Gmail blocked in China?
Gmail has been largely inaccessible in mainland China since 2014, as part of China's internet censorship (Great Firewall) that blocks foreign services deemed non-compliant with Chinese regulations. The block is attributed to Google's refusal to comply with Chinese data localization requirements and censorship rules following Google's partial withdrawal from China in 2010. Access to Gmail in China typically requires VPN connections, though reliability varies.
What email services do Chinese people use?
Chinese internet users primarily use QQ Mail (Tencent) for personal email due to its integration with the QQ messaging platform. 163 Mail (NetEase) is the second most popular. For enterprise email, Tencent Enterprise Mail and Coremail are market leaders. Many young Chinese rarely use email for personal communication, relying instead on WeChat messaging. Email remains essential for business correspondence, job applications, academic communication, and international trade.
How do businesses handle international email from China?
Chinese businesses communicating internationally face email challenges including Gmail blocking and unreliable foreign email service access. Solutions include: using enterprise email services with dedicated international relay servers, employing CDN-accelerated email delivery, maintaining mail servers in Hong Kong for better international connectivity, using VPNs for Gmail access, and routing international correspondence through enterprise email providers with international infrastructure partnerships.
Is WeChat replacing email in China?
WeChat has largely replaced personal email for day-to-day communication in China. Over 90% of Chinese smartphone users use WeChat for messaging, payments, and social networking. However, email remains essential for: formal business communication, legal correspondence, job applications, academic communication, government interactions, international trade, and enterprise workflows. The typical Chinese professional uses WeChat for quick coordination and email for formal documentation and external communication.
What enterprise email features do Chinese companies need?
Chinese enterprises require: data localization (servers within China per Cybersecurity Law), integration with domestic communication tools (WeChat Enterprise, DingTalk), anti-spam optimized for Chinese language content, regulatory compliance features (audit logs, data retention), mobile-first design, custom domain support, large attachment handling, and reliability for high-volume business communication. State-owned enterprises additionally require security certifications and government-approved encryption standards.
