问题描述
The official demo email sending API (https://react.email/api/send/test) has been returning 429 Too Many Requests for over 24 hours, making it impossible to test email sending through the preview UI.
Request Details
- Request URL:
https://react.email/api/send/test
- Request Method:
OPTIONS (preflight)
- Status Code:
429 Too Many Requests
- Remote Address:
76.76.21.21:443
- Referrer Policy:
strict-origin-when-cross-origin
Steps to Reproduce
- Open the react-email local dev preview
- Click "Send Test Email" button
- The OPTIONS preflight request to
https://react.email/api/send/test returns 429
Expected Behavior
The test email API should be available for normal usage, or at minimum the rate limiting should be relaxed to allow reasonable testing.
Additional Context
This appears to be a server-side rate limiting issue on the react.email domain. The 429 status has persisted for over 24 hours (since ~2026-03-09), suggesting it may not be a temporary spike but a configuration issue.
