Can I open-source Airmail?
KINDA · partial or early alternativesKinda. Stalwart and Listmonk cover the core of Airmail, but they're early or partial — expect gaps like native apps, provider quirks, automation, push, and years of compatibility work and mail hosting and deliverability.
People still pay for Airmail because an email client can be rebuilt; operating a trusted mail service with excellent deliverability cannot. The recurring cost buys IMAP quirks, OAuth, MIME, threading, search, attachments, offline sync, notifications, secure storage, and provider changes, not just the visible interface.
