TempMailix is a browser-based temporary email service designed to help people protect their personal inboxes and reduce unwanted spam. It generates disposable email addresses instantly, without requiring registration, payment, or personal information. Users can choose from available domains, copy or share an address, and open a live inbox to receive messages such as verification codes and order confirmations. The service is free to use and works on phones, tablets, and desktop devices without downloads.

TempMailix is intended for one-time website signups, newsletter previews, online shopping, and registrations on sites users may not fully trust. Developers and QA teams can also use its addresses to test email workflows, staging environments, and verification processes; an API is mentioned for developer use. Inboxes receive messages only, refresh automatically, and expire after a limited period, with messages removed when the mailbox expires. Addresses remain usable during an active session, but expired inboxes cannot be recovered.
