Free Overseas Email Signup: Proton Step-by-Step Guide (2026)
If you want to register for ChatGPT, OpenAI, Claude, and other overseas services, the hardest step is often getting an overseas email address. Many email providers charge money or force phone verification. This guide uses Proton Mail to get your first free overseas email — no phone number required.
Quick conclusion: The whole signup takes about 5–10 minutes. The core is just three steps — visit the official site → pick the free plan → set your username and complete the captcha. The key point: phone verification can be skipped.

Pros and Cons
Advantages of a free Proton mailbox
- No phone number: only a captcha, no SMS required — privacy-friendly
- Free and enough: 1GB storage plus a daily mail quota is fine for registering overseas accounts
- Chinese interface: beginner-friendly, in both registration and daily use
Limitations / things to note
- Limited storage: 1GB suits an "entry email," not a heavy daily mailbox
- Free tier has trade-offs: custom domains and more aliases require a paid plan
- Depends on the network: reaching Proton and receiving mail needs overseas access
Who It's For
- Users registering ChatGPT, OpenAI, Claude, Notion and more but lacking an email address
- Privacy-conscious people who don't want to bind a phone number
- Beginners who want a free overseas email with zero budget
