FoldMail is a native email client for people who take their inbox seriously: developers, scientists, journalists, administrators. Security is an architecture constraint, not an afterthought. No tracking, no third-party libraries, fully keyboard-operable.
Six building blocks for email without distraction, built for people who want to know what goes over the wire.
Everything you can do is reachable by typing. Search operators like from:, has:attachment, before:2024-06 and /regex/ inline, the same grammar in UI, CLI and filters.
Raw IMAP/SMTP trace at a keystroke, kept in a RAM ring buffer instead of on disk. For everyone who wants to follow what actually happens over the wire.
A reply starts with the To field. Cc, Bcc, attachments and encryption appear only on a gesture or shortcut. What is visible has to earn its visibility.
End-to-end encryption via Apple鈥檚 Security.framework and a modern OpenPGP subset (Ed25519, X25519). Fingerprints are shown, not hidden.
The fold CLI with git-style subcommands, a stable JSON schema and documented exit codes. Filters, shortcuts and widgets all speak the same language.
Enter your address and FoldMail finds the servers itself, via a signed provider database, DNS and ISPDB. You see which servers will be used before the first connection.
FoldMail is in active development for macOS, iPadOS and iOS. Request early access or follow the roadmap at foldmail.app.
