Temporary email that never leaves you waiting.
Open an address, paste it into any mobile app or website, and copy your verification OTP straight from the push notification. Zero full-screen ads. Maximum privacy.
Built for power users and privacy advocates.
We benchmarked the top temp mail apps on Android and iOS to eliminate their worst flaws: invasive ad trackers, battery drain, and unskippable video popups.
Interactive Lock Screen Push
When a verification code arrives, Mailby delivers a push notification with a dedicated 'Copy OTP' action button right on your lock screen.
Biometric Multi-Inbox Vault
Manage unlimited active disposable addresses at once. Secure sensitive verification mail behind Face ID or Fingerprint authentication.
Zero Remote Trackers & Spy Pixels
Senders often embed 1x1 invisible GIFs to track your IP and read status. Mailby's sandboxed viewer strips tracking scripts and external beacons automatically.
Zero Full-Screen Ad Spam
Most free temp mail apps bombard you with 30-second unskippable video ads just to view a verification code. Mailby is brutalist, fast, and respectful.
Cryptographic Recovery Keys
Need to access your temporary address later? Export an AES recovery key or QR code to restore your inbox across phone, tablet, and desktop.
Real-Time WebSocket & Push Sync
Messages land within 400ms via our low-latency LMTP ingestion engine, triggering instant vibration and haptic feedback.
