Everything you need to know about temporary email

TempMail Ninja lets you create disposable email addresses without signing up. In seconds you get a temporary inbox to receive—and, in some cases, send emails—while keeping your real address private.

Use it for forms, downloads, trials, or whenever you prefer to avoid spam and protect your identity.

A disposable email address created for short-term use that self-deletes after a set period. No personal data required and your real inbox stays protected.

• Perfect for quick sign-ups and testing.
• Reduces spam and data exposure.
• Easy to discard without impacting your main inbox.

We offer several lifespans:

• Public domains: up to 3 months.
• Private domains (registered users): up to 8 months.

After expiry, the address is invalid and can no longer send or receive emails.

Yes. You can select from:

• Public domains: available to everyone; up to 3 months.
• Private domains: for users logged in with Google; up to 8 months and typically fewer blocks.
• Premium domains: in development with additional features planned.

Messages are listed chronologically. When opening a message you can:

• Read HTML/TXT content.
• See sender, subject, date and basic metadata.
• Download attachments (if any).

Retention: messages auto-delete after 48 hours. You may delete them earlier manually.

Yes. From the “Send message” page you can compose and send. Limitations:

• Rate: 1 email per hour per address.
• Retention: sent emails auto-delete after 48 hours.
• Delivery: not guaranteed; some providers apply strict anti-spam filters.

For better deliverability, prefer private domains when available.

• Registered (Google): private domains, reply to messages, send attachments, and manage up to 25 addresses.
• Non-registered: public domains only and up to 10 addresses stored.

Registration unlocks more features and typically improves acceptance.

Yes. From your dashboard you can:

• Set a custom alias.
• Choose the domain available to your user type.
• Protect access with a Password (optional).

Enable the Password option in your dashboard. Important:

• Passwords are not recoverable.
• If you forget it, you will lose access to that inbox (privacy-first design).

• Remove from list: the address remains active; it is simply hidden from your panel.
• Delete permanently: the address is erased and can no longer send or receive emails.

Some platforms block disposable addresses to reduce abuse. Tips:

• Prefer private domains if you're registered—they are less likely to be filtered.
• Avoid uses that may violate the recipient's terms of service.

Yes. We don't request personal data and you can create anonymous addresses. Adding a password increases access security.

Still, avoid sending highly sensitive data: the goal is practical privacy and spam reduction.

Remove: only hides the address from your dashboard; the inbox remains usable.

Delete permanently: removes the inbox; it cannot be used again and its content is lost.

Yes. It works on modern desktop and mobile browsers. No installation required.

To rotate and refresh inventory:

• Public: retired after ~3 months.
• Private: up to ~8 months.

Once retired, they are no longer available to create new addresses.

• Public: one per week.
• Private: one per month for registered users.

Yes. It's a legitimate privacy tool. Note some services may refuse it for sign-ups or subscriptions.

From your dashboard, as long as the address is still within its validity period. If it was password-protected, you will need that password.

Check your dashboard: if the address is still active, it will be listed. If it was password-protected and you forgot the password, it is not recoverable.

Yes. The 10-minute email auto-deletes after the time is up. Limitations:

• No sending capability.
• No customization (alias/domain).

• Use the service responsibly and follow the Terms & Conditions.
• Avoid abuse that could hurt deliverability.
• Prefer private domains when you need better acceptance.
