Email that reads you.
Now it just works for you.
Sift is a privacy-first desktop email client that connects directly to your provider over IMAP & SMTP. No middleman servers, no content scanning, no ad profiling — your mail stays on your machine, fully encrypted at rest.
We never read your mail
Zero content scanning. No keyword indexing on our servers — because there are no servers in the path. Sift talks to your provider directly.
Your data stays local
Messages, attachments, and search indexes live in an encrypted store on your device. We collect no telemetry, no crash pings, no analytics — nothing.
Verifiable, not promised
The core sync engine is open source and reproducibly built. Audit the network traffic yourself — what we say is exactly what the binary does.
Keyboard-first workflow
Vim-style bindings, fuzzy command palette, and snippets. Triage a thousand messages without touching the mouse.
Instant local search
A full-text index built on your machine returns results in milliseconds — across millions of messages, fully offline.
Tracker & pixel blocking
Remote images are proxied or stripped, tracking pixels neutralized, and link rewrites flagged before you click.
on by defaultPGP & S/MIME
Sign and encrypt with your own keys. Web Key Directory support means encryption that's actually usable day to day.
Unified, multi-account
Gmail, Fastmail, Proton Bridge, self-hosted IMAP — one window, infinite accounts, no per-account upsell.
Native & lightweight
Written in Rust, not a browser shell. Cold start under 400 ms and a memory footprint a fraction of the usual.
Offline-complete
Read, write, search, and queue sends on a plane. Everything syncs cleanly the moment you reconnect.
