FairEmail

FairEmail is an open-source email client for Android that supports standard IMAP and SMTP protocols. It serves as a privacy-focused communication tool that manages multiple accounts through a unified inbox and provides PGP encryption and decryption for secure messaging.

The application prioritizes data privacy by blocking tracking pixels and requiring manual confirmation before loading external images. It secures sensitive information through biometric authentication and personal identification numbers to restrict unauthorized access to the device.

The client includes a suite of organization and automation tools, including custom filter rules, scheduled sending, and configurable swipe gestures for inbox management. It maintains a local-first data model with on-device search indexing, offline message access, and the ability to synchronize meeting invitations with the device calendar.
