MailBot — Disposable email

MailBot — Temporary Email & OTP Inbox

MailBot gives you a disposable email address directly in Firefox, so you can receive verification emails without exposing your real inbox.

Create a temporary address, paste it into a signup or login form, and open MailBot to see incoming messages. When a one-time password or verification code arrives, MailBot detects it, highlights it, and makes it easy to copy.

What it does

• Creates temporary email addresses in one click
• Detects OTP and verification codes automatically
• Shows incoming mail inside the extension
• Highlights the code so you can copy it quickly
• Works from the popup or side panel
• Lets you open the full message in a comfortable drawer view
• Keeps addresses temporary — each address expires after 24 hours
• Supports light and dark themes
• Includes English and Russian UI
• Open source under the MIT license

MailBot for Firefox checks your temporary inbox automatically.

When the popup is open, the inbox refreshes frequently so new messages and codes appear quickly. In the background, MailBot also checks periodically and can show a browser notification when new mail arrives.

No Web Push setup is required in Firefox.

How to use it

1. Click the MailBot icon.
2. Create a temporary address like name@mailbot.click.
3. Paste it into a signup, login, trial, or verification form.
4. Open MailBot to read the message and copy the detected OTP code.

MailBot is built for temporary email use.

• No account is required.
• No personal email address is required.
• Authentication uses an anonymous device token stored on your device.
• The server stores only a hash of that token.
• Incoming messages are stored as normalized text only, not raw MIME.
• Attachments are not stored.
• Messages and addresses expire after 24 hours.
• The extension has no ads, trackers, or analytics.

Important

MailBot is for temporary verification emails, throwaway registrations, testing, and short-lived inboxes.

Do not use it for important accounts, banking, password recovery, legal, medical, or long-term communication. Temporary addresses expire and stop receiving mail after their lifetime ends.
