Bypass Email Verification
Every service requires email verification. With mail123.fr, receive your code in seconds without exposing your real address. Works with ChatGPT, GitHub, PayPal, Apple, OpenAI and hundreds more.
Why do sites require email verification?
Email verification has become the web's standard anti-bot measure. By sending a link or code to your address, the service confirms you actually control that inbox. It's a simple technique, but it has a side effect: it forces users to expose their real email address, often for simple tests or one-time access.
The solution: A temporary email from mail123.fr is a real inbox — not an alias, not a forwarder. Verification emails arrive in real time, you can click the confirmation link, and your real address stays out of the loop.
Most common use cases
One-time verification (account activation)
Most services only send one verification email at sign-up. This is the ideal case for a disposable email: you receive the link, click it, the account is activated, and you no longer need that address.
Two-step verification (email 2FA)
Some services send a code at every login. If you use a temporary email, this 2FA will stop working after the inbox expires. In that case, disable email 2FA from the account settings, or switch to an authenticator app (Google Authenticator, Authy).
AI tools & APIs (ChatGPT, OpenAI, GitHub)
AI platforms like ChatGPT, Claude, Gemini require an email at sign-up. A temporary email lets you test these services without creating an account tied to your permanent identity — useful for professional evaluations or integration testing.
GitHub, APIs & development
For developers, email verification is everywhere: GitHub, GitLab, npm/PyPI registries, SaaS dashboards, API sandboxes. A disposable email lets you:
- Create test accounts for your staging environments
- Test your own sign-up and activation flows
- Evaluate third-party tools without polluting your professional address
- Generate disposable API keys linked to ephemeral accounts
Info: To automate this workflow, the mail123.fr API is available at /api/mailbox/<box> — see the documentation to integrate email reception into your test scripts.
PayPal, Apple, financial services
These services are more sensitive to email quality. If your goal is to create a permanent PayPal or Apple account, use your real address. However, for testing a payment service or evaluating a sandbox, a temporary email works perfectly for initial activation.
Warning for PayPal: A PayPal account with an expired email won't be able to send password resets or transaction confirmations. For real financial use, keep your real address.

Frequently asked questions
Do AI tools detect temporary emails?
Some services maintain blacklists of known disposable email domains. mail123.fr uses domains not listed in these databases — but no absolute guarantee is possible. If a service rejects our domain, try another among the 4 available.
How long do I have to click the verification link?
The inbox is active for 7 days. Verification links typically expire within an hour on the sender's side — not ours. Act as soon as you receive the email.
Can I receive multiple verification codes in the same inbox?
Yes. You can register the same email on multiple services simultaneously. All emails arrive in the same inbox, sorted by date and sender.
