installPreinstalled on macOS, iPhone, and iPad; add an IMAP, Exchange, iCloud, Google, or other supported mailbox

installInstall Spark on macOS, Windows, iOS, or Android, create a Spark account, and connect existing mailboxes
enginesOptional Spark +AI and AI Assistant features use third-party large-language-model providers; the ordinary free mail client does not require AI
dataMail remains at the provider and is indexed locally; encrypted synchronization and notification metadata, and temporarily queued send-later messages, can live on Spark's servers; AI excerpts may be sent to a disclosed provider when AI is used
the catch vs AirmailSpark Free is polished but offers less granular action and automation customization than Airmail and requires a Spark account for synchronization.
setupRequires a Spark account and mailbox OAuth or credentials, but no server administration

La gente todavía paga por Airmail porque un cliente de correo se puede reconstruir; operar un servicio de correo confiable con excelente entregabilidad no. El costo recurrente compra peculiaridades de IMAP, OAuth, MIME, hilos, búsqueda, adjuntos, sincronización offline, notificaciones, almacenamiento seguro y cambios de proveedores, no solo la interfaz visible. If none of that applies to you, any pick above saves $95.88 a year.
Is there a free alternative to Airmail?
Yes: Apple Mail, Edison Mail, Spark Free. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Airmail?
Our verdict is PARCIAL. El ciclo principal es construible, pero un reemplazo confiable se convierte en un proyecto real de fin de semana o varios días. Para Airmail, crea un cliente de correo configurable para Apple con acciones, posponer y envío programado. El límite duro son las apps nativas, peculiaridades de proveedores, automatización, push y años de trabajo de compatibilidad, más la infraestructura de correo, integraciones y pulido del cliente. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/airmail.
