solid inbox zero tool
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Spark's Smart Inbox and Priority highlight messages from important people and bundle newsletters and notifications so the rest of your inbox stays quiet.
An AI Assistant lets you find, summarize, and take action on anything in your inbox, while an AI writing assistant drafts emails and Auto-Drafts pre-writes replies.
Translate incoming messages, get instant summaries of long threads, and quickly grasp the point without reading every line.
Share drafts, leave private comments, delegate ownership, and track progress on email threads with your colleagues.
Gatekeeper blocks unwanted senders, while Snooze, Send Later, Set Aside, and Reminders help you manage time and follow-ups.
Spark Mail is a smart email client built to reduce information overload. Instead of treating every message the same, it separates what matters from what can wait: Priority flags emails from important contacts, Group by Sender bundles messages, and dedicated Newsletter and Notification inboxes keep automated mail out of your main view. Tools like Gatekeeper, Snooze, Send Later, Set Aside, and Reminders round out the workflow.
AI is woven throughout the experience. An AI Assistant can find, summarize, and act on anything in your inbox; Spark's writing assistant helps you compose better emails faster; Auto-Drafts prepares replies in advance; and built-in translation and summary features help you handle long or multilingual threads. Calendar and meeting notes support keeps scheduling connected to your mail.
Spark is cross-platform — iOS, macOS, Windows, Android, and web — and syncs accounts across devices, supporting IMAP, iCloud, Exchange, Outlook, Yahoo, and Google. It is well established, cited as an Apple Editors' Choice app with more than 21 million users, and offers both personal and team-oriented plans. For teams, it adds shared drafts, private comments, assignment of email ownership, and progress tracking.
Combine personal and work accounts, surface what matters with Priority, and silence newsletters and notifications.
Draft replies, translate messages, and summarize long threads with AI to answer faster and more clearly.
Share drafts, leave private comments, delegate email ownership, and track deadlines across a team.
