What is temp mail and how does temporary email work?

Temp mail (temporary email) is a disposable email service that creates instant email addresses that expire after a set time. Temp Postal generates secure temporary emails in 0.5 seconds with military-grade encryption, protecting your real inbox from spam and privacy breaches.

Is temp mail safe and secure to use?

Yes, Temp Postal uses AES-256 military-grade encryption with zero-knowledge architecture. We don't log IP addresses, store personal data, or track users. Your temporary emails are completely private and secure.

How long do temporary emails last?

Temp Postal offers the longest storage in the industry: 48 hours for free accounts and up to 30 days for premium accounts. Most competitors only offer 10 minutes to 24 hours.

Can I use temp mail for important signups?

Yes! Our temporary emails work with all major services including social media, e-commerce, software trials, and more. We support attachments, HTML emails, and have 99.9% delivery rates.

Is using temp mail legal in the United States?

Yes. Creating and using a disposable email address is legal in the US and every other country Temp Postal serves. Temporary email is a privacy tool, the same as a password manager. Signing up for a newsletter, a trial or a forum is fine; using it to commit fraud or evade a ban breaks the service's terms, not the law.

Can temp mail receive verification codes and OTPs?

Yes. Temp Postal inboxes receive verification links, one-time passcodes and 2FA emails in real time, usually within two seconds of the sender dispatching them. Codes stay readable for 48 hours on the free tier, so you can finish a signup later without losing the message.

Does temp mail work for Gmail, Netflix or Amazon signups?

It works with most services. Temp Postal rotates 20+ real delivering domains, so acceptance is far higher than single-domain services. Some providers - notably Google account creation and a few banking apps - block all known disposable domains, so use a permanent address for accounts you intend to keep.

Temp Postal vs temp-mail.org: what is the difference?

Temp Postal keeps messages for 48 hours free (30 days on paid plans) versus the short windows most classic services offer, runs 20+ domains instead of a small shared pool, exposes a documented REST API for QA automation, and does not log IP addresses. It is built for people who need the inbox to still be there tomorrow.

Do I need to sign up or install anything?

No. Opening temppostal.com generates an address instantly - no account, no email confirmation, no app or extension. Accounts are optional and only unlock longer retention, custom domains and API keys.

Can anyone else read my temporary inbox?

Your address is randomly generated and unguessable, and inboxes are encrypted at rest with AES-256. Anyone who knows the exact address could open it, so treat temp mail as disposable and never route passwords, financial statements or personal documents through it.

What happens to my messages when the inbox expires?

Messages are permanently deleted when the retention window ends - 48 hours on the free tier, up to 30 days on paid plans. Deletion is irreversible and nothing is archived, so download any attachment you need before the timer runs out.
