Our verdict

Spark is the rare free email client with no asterisks that matter. Readdle's client runs beautifully on Mac, Windows, iOS, and Android, with a Smart Inbox that sorts mail into personal, notifications, and newsletters, Gatekeeper screening for unwanted senders, and — on Premium (~$5 a month) — AI writing assistance, thread summaries, and priority inbox features. Team plans (~$6.99/user/mo) add shared drafts and delegation. For most people, the free tier alone is a massive upgrade over default mail apps. Privacy-conscious users should note the server-side processing that powers the smart features, and dedicated shared-inbox teams will outgrow it toward Missive or a helpdesk. But as the default recommendation for ‘I just want a better inbox,’ Spark wins on the combination of polish, platforms, and price. Start free; pay only if the AI features earn it. Scores on this page are research-based, compiled from official documentation and public user feedback.
