Privacy First

UnifyMail syncs your mail locally using its C++ engine. Your credentials stay in your OS keychain, and your email data never touches our servers.

  • Local-only IMAP/SMTP sync — no cloud relay
  • Credentials stored in OS keychain
  • No tracking, no ads, no data selling

Lightning Performance

Powered by a native C++ sync engine based on Mailcore2, UnifyMail uses roughly half the RAM and CPU of other Electron-based mail clients.

  • C++ sync engine for native speed
  • Half the RAM & CPU of competitors
  • Near-zero idle CPU wakes for great battery life
