What is temp mail?
Temp mail (temporary mail) is a disposable email address that works instantly and requires no signup. You use it to receive verification codes and one-off emails without exposing your real inbox. nullmail generates an address the moment you open the site, and the inbox hard-deletes itself after expiry — nothing is stored, nothing leaks.
How it works
- Open the app. A fresh address is already waiting. No form, no email, no phone number.
- Use it. Paste the address into any signup, trial, or download form.
- Read the code. The inbox polls automatically and extracts OTP codes and login links for one-tap copy.
Honest limit: this receives email verifications. Services that verify by SMS need your phone number, and no email tool changes that.
What you can do with nullmail
- Protect your real inbox — never hand your personal address to a service you don't trust yet.
- Stop spam before it starts — when the address starts attracting junk, let it expire and generate a new one.
- Test accounts safely — QA teams use a fresh disposable inbox per test run, with automatic cleanup.
- Stay anonymous by default — no account, no PII, hard-delete on expiry.

Questions, answered
Is temp mail free?
Yes. nullmail is completely free with no account and no personal data. You open the site and a working disposable address is already waiting — there is no paid tier and no trial limit.
Can temp mail receive verification codes?
Yes. The inbox polls automatically and receives real email, including OTP codes and login links, usually within seconds. nullmail detects the code and offers one-tap copy so you can verify without switching tabs.
How long does a temp mail address last?
Inboxes auto-expire after a set time and every message is permanently deleted at expiry. Expiry is irreversible by design, so never use temp mail for an account you may need to recover later.
Is using temp mail legal?
Yes. Using a disposable address for lawful signups is legal in essentially every jurisdiction. Laws target what you do with an account, not which email provider you choose — fraud and ban evasion stay illegal regardless.
Can I send email from temp mail?
No, nullmail is receive-only. It deliberately cannot send mail, which structurally prevents the service from being used as a spam relay and keeps deliverability high for incoming verification codes.
