Mailbird vs Mailspring
Side-by-side comparison of features, pricing, ratings, and alternatives.
Mailbird is a desktop email client that consolidates Gmail, Outlook, Yahoo, iCloud, Exchange and any IMAP/SMTP account into a single unified inbox. It layers on productivity features like email tracking, a built-in AI writing assistant, one-click unsubscribe, and integrations with apps such as Slack, Google Calendar, Dropbox and Asana without leaving the inbox. The app is built around a customizable interface, with theming, keyboard shortcuts and layout options, and claims around 4.4 million users. It ships as a one-account free version alongside a paid Premium tier that unlocks unlimited accounts and the full integration set, sold as either a one-time lifetime purchase or an annual subscription.
Mailspring is a native desktop email client from independent studio Foundry376, built for Mac, Windows, and Linux. It unifies accounts from Gmail, iCloud, Office 365, Outlook.com, Yahoo, FastMail, and generic IMAP/SMTP providers into one fast, searchable inbox with Gmail-style search syntax. 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.
