About Spark Mail
Spark Mail is an email client for iOS, macOS, Android, and Windows that uses AI to automatically separate important personal emails from newsletters, notifications, and team messages - without requiring manual filters or rules. Its Smart Inbox groups emails by type so you read the important messages first and batch-process the rest. Spark AI generates email drafts from a short description, adjusts tone (formal, friendly, concise), improves grammar and clarity, and can shorten or expand a draft to match the situation. The Gatekeeper feature allows you to approve new senders before their emails reach your inbox - a useful spam reduction mechanism for inboxes that receive high volumes of cold outreach. Team collaboration features let multiple people draft a reply together, leave internal comments on email threads, and assign emails to teammates as tasks - without the recipient seeing the collaboration layer. Send Later and Remind Me controls turn Spark into a light task layer on top of email. Supports Gmail, Outlook, Exchange, iCloud, Yahoo, IMAP and most major providers. Free plan covers individual use with full AI access; Premium plan adds team features.
