Spark Mail
AI email client with a Smart Inbox, sender Gatekeeper, and team collaboration across every platform.
About
Spark Mail is Readdle's cross-platform email client, built around a Smart Inbox that sorts mail into personal, notifications, and newsletters, plus a Gatekeeper that screens first-time senders so strangers never land in your inbox uninvited. The Spark +AI layer drafts replies, rewrites tone, summarizes long threads, and answers questions about your mail; teams get shared drafts, internal comments, and email delegation. It connects Gmail, Outlook, iCloud, Exchange, Yahoo, and any IMAP account, with apps for Mac, Windows, iOS, Android, and Apple Watch.
Spark has been a fixture since 2015 (Readdle claims 19.5M+ downloads and an Apple Editors' Choice nod — both provider-claimed). A free plan covers unlimited accounts and core triage; paid tiers start around $5–10 per user per month. Plan names and prices have shifted several times, so check the vendor site before committing.
