Mailspring vs Spark Mail
Side-by-side comparison of features, pricing, ratings, and alternatives.

Its free tier covers core mail management, while the $8/month Pro plan adds read receipts, link tracking, send-later scheduling, follow-up reminders, templates, and contact enrichment (with limited weekly trials of Pro features in the free app). The client emphasizes native platform integration, including Windows taskbar badges, macOS notifications, and Linux system tray support.
