What it is

TempInbox is a free web service for temporary email inboxes without signup. It is intended for verification messages, trials and low-trust registrations, with developers, QA teams and privacy-conscious users among its stated audiences. One browser can hold up to three inboxes, and access is saved in that browser. The Free plan costs nothing and has no 10-minute timer, but inbox lifetime is custom. Messages may be soft-deleted and later removed in scheduled batches, so long-term storage is not guaranteed. The browser interface lets users view, download and clear messages, including attachments. Hosted TempInbox is receive-only: it has no sending, replies or forwarding, and no supported public API or SDK. It works in Android and iPhone mobile browsers without an app. The maker describes privacy and security as best-effort and warns that messages may be exposed, delayed, removed or inaccessible. It advises against banking, medical, legal, payroll and other high-stakes accounts requiring lasting confidentiality.
