eM Client vs Spark Mail
Side-by-side comparison of features, pricing, ratings, and alternatives.
eM Client is a desktop email application for Windows and macOS (with companion Android/iOS apps) positioned as an alternative to Outlook and Thunderbird. It bundles email, calendar, tasks, notes, and chat into one interface, with inbox categorization, quick actions, and an AI add-on for drafting and summarizing. The free tier covers up to two accounts for personal, non-commercial use, while paid Personal and Business licenses remove that account limit and unlock features like PGP message encryption, snooze, translation, and mass mail tools. Licenses are available as annual subscriptions or one-time lifetime purchases, and mobile apps are free without a separate license.
