Send a message to your temp address and it will show up here instantly.

A deliberately narrow tool

Useful for the temporary job. Wrong for the important one.

TmpKit receives mail; it cannot send it. The address is not an identity, an archive, or a secure account-recovery channel. That constraint is the product, not a footnote.

Good fit

  • QA checks for sign-up, verification, and password-reset delivery
  • Low-risk confirmations you will not need after the session ends
  • Keeping one-off vendor mail away from a permanent inbox

Use a real mailbox instead

  • Banking, healthcare, government, work, or paid accounts
  • Anything confidential, sensitive, or needed for future recovery
  • Evading identity checks, bans, usage limits, or another service's rules

What we publish, not what we promise

We document the actual session lifecycle, inspect the disposable-domain dataset used by our checker, and publish a reproducible mail-delivery test protocol. Results and limitations are separated from marketing claims.

Frequently Asked Questions

Can I receive verification codes and confirmation links?
Yes. Receiving low-risk one-time codes and sign-up confirmations is what TmpKit is built for. Delivery time depends on the sender, DNS, SMTP queues, and inbox polling, so no fixed arrival time is guaranteed. If a code is delayed, check the sender's status and resend controls before the sender's own expiry window closes.
How long does my address and inbox last?
Each address is short-lived by design and expires after the countdown shown in the app. When it expires, the session stops returning its messages and old records enter the cleanup process. If you need the address a little longer, use the one-time extension when offered and grab the code before the window closes.
Can I reply to emails or send messages from a temp address?
No. tmpkit is a receive-only service, so you can read incoming mail but not compose, reply to, or forward anything from the temporary address. If a workflow requires you to send email, you will need a real mailbox you control.
Are attachments supported?
Yes, you can usually open and download attachments that arrive with a message, such as PDFs or images. Very large files may be rejected by mail-size limits, and like everything else in the inbox, attachments disappear when the address expires. Download anything you want to keep before that happens.
Is it really anonymous, and what data do you keep?
No account, name, or password is required for an inbox, but the service and its infrastructure still process the temporary address, message, session ID, IP, request, and security data needed to operate. Messages stop being available at session expiry and old records enter cleanup; limited technical logs may be retained for security, reliability, debugging, or legal duties. This reduces the data footprint but is not guaranteed anonymity.
