Smart email app with AI writing and inbox summaries Category: Productivity & Automation.
Spark is a cross-platform email client from Readdle that combines a smart, prioritized inbox with an AI assistant aimed at individuals and teams who want a calmer email experience.
Its Smart Inbox automatically groups and surfaces important messages, while the AI features let you summarize long threads for instant context, draft and refine replies with an email writing assistant, and translate messages to break language barriers.
Spark also supports collaborative email through shared inboxes, comments, and the ability to delegate or discuss messages privately with teammates before sending, making it useful for support and shared mailboxes. It runs across iPhone, iPad, Mac, Apple Watch, Android, and Windows, so your inbox stays consistent everywhere.
People choose Spark to reduce inbox clutter, write better emails faster, and collaborate on mail without forwarding chains. Its strengths are a genuinely capable free tier, polished multi-platform apps, and team collaboration features that many consumer clients lack.
The trade-offs are that unlimited AI usage and advanced team features require the Premium subscription, and connecting multiple accounts and tuning the Smart Inbox can take some setup. Some longtime users have also noted that major version changes can shift familiar workflows.
Even so, for individuals and small teams wanting a calmer, AI-assisted inbox across every device, Spark remains an approachable and capable choice. Spark uses a freemium model with a free plan and a Premium subscription. Pricing changes often, so check the official site for current plans.
