Suiyongsuiqi offers disposable email for sign-ups and short-term inbox use to reduce spam and privacy exposure. Basic usage is free with a daily quota, and transactional inboxes are available for business needs.

Basic usage is available without registration. Log in only when you need purchases or mailbox management.

Both random and custom prefixes are supported.

The inbox supports automatic refresh and manual refresh for timely updates.

Free usage resets daily. Random and custom prefixes are tracked separately and reset automatically.

After login you can purchase private mailboxes, buy in batches, top up balance, and manage everything in My Mailboxes. You can also generate API keys for automation.

Try another prefix or choose a different suffix and retry.

No. Mail detail pages are private and are excluded from indexing by default.

Generate an API key in the API Key page to access mailbox APIs programmatically (buy, query, fetch mail, etc.).
