About TempBox
TempBox is a free disposable temporary email service. We built it because every other option in this space is either too slow, too ugly, too restrictive (10-minute limit), or packed with dark patterns designed to keep you confused. TempBox is different: you get a real working inbox instantly, for as long as you actually need it.
We're funded by non-intrusive advertising. We collect zero personal data. The service runs entirely on Cloudflare's global edge network — which means your emails arrive in seconds, anywhere in the world.
🚀 Why we built this
Spam is a solved problem — if you use throwaway addresses. But existing tools made it painful: ugly UIs, 10-minute limits, one inbox at a time. TempBox fixes all of that.
🔒 Privacy first
No accounts. No tracking. No IP logging. Emails auto-delete. We built the infrastructure so that we cannot read your messages even if we wanted to.
⚡ Real-time delivery
Emails arrive in under 5 seconds in most cases. Verification codes, OTPs, and welcome emails appear before you've even switched tabs.
Email Address Validator
Check whether an email address has a valid format. This validates the structure of the address (local part, @ symbol, domain) — it does not send a test email or verify that the mailbox exists.
Valid email formats
user@example.com
user.name@example.com
user+tag@example.co.uk
user123@subdomain.example.org
Invalid email formats

What is disposable email?
A disposable email address is a temporary email that you can create instantly, use to receive emails, and then discard — all without providing any personal information. The concept dates back to the early 2000s, but modern tools like TempBox make it dramatically faster and more useful.
Common use cases include: signing up for free trials, downloading gated content (ebooks, reports), testing your own applications, protecting your identity when posting in public forums, and avoiding mailing list subscriptions you don't want.
