Frequently Asked Questions
Short answers to the questions we get most often.
- Do I need to register?
- No. The inbox is generated automatically the moment you land on the home page. There is nothing to sign up for.
- How long does an inbox live?
- It depends on the lifetime you pick: 10 minutes, 30 minutes, 1 hour (the default), 6 hours, or 24 hours. Each new message or refresh extends the lifetime.
- Can I send email from a TempMailbox address?
- No. TempMailbox is receive-only. Sending would expose users to abuse-handling problems we have deliberately stayed out of.
- Does it support attachments?
- Yes. Attachments are listed with name, content type, and size. Downloading is intentionally limited for safety.
- Can a website block TempMailbox?
- Yes — some do, especially for high-trust services like banking. That is a reasonable choice on their end and not something we try to circumvent.
- Is it free?
- Yes. The free tier covers all standard disposable-inbox use. Pro plans exist for longer lifetimes, custom local parts, and bring-your-own-domain.
- Is my mail private?
- Inboxes are publicly addressable — anyone who guesses the address could read messages there. Treat a TempMailbox inbox as a public bulletin board, not a vault.
- Can I use a custom address?
- Yes. Pick any local part on a supported domain. If the inbox does not yet exist, it will be created.
