What TempInbox is
TempInbox is a web service for receiving mail in temporary inboxes, with no signup required. The maker describes it as useful for developers, QA teams, and privacy-conscious users who need verification messages or mail for trials and low-trust signups. One browser can hold up to three inboxes, and access to them is saved in that browser. There is no 10-minute timer, but inbox lifetime is custom: messages may be soft-deleted and later permanently removed in scheduled batches, so long-term storage is not guaranteed. The browser interface lets users view, download, and clear messages, and attachments are supported. Hosted TempInbox receives mail only; it does not send, reply to, or forward messages. The service is intended for manual browser use and has no supported public API or SDK. It also works in Android and iPhone mobile browsers without an app installation. The maker describes its privacy and security as best-effort, with controls including rate limiting, bot and abuse measures, token-based mailbox access, cleanup routines, and infrastructure-level protections. It warns against using TempInbox for accounts that need long-term access and strict confidentiality.
