Spark

Spark is a cross-platform email application designed to help users manage their inboxes with a focus on speed, clarity, and productivity. It works on Windows, macOS, Android, iPhone, iPad, and Apple Watch, offering a consistent experience across devices. The app’s core goal is to reduce email overload by automatically filtering out less important messages and surfacing what truly matters. One of Spark’s key features is its priority system. Users can mark specific contacts as high priority—their emails appear at the top of the inbox with a visual indicator. This ensures that messages from colleagues, clients, or family members are never missed. Conversely, routine newsletters, notifications, or automated messages can be grouped and tucked away. The “Group by Sender” option clusters all emails from the same person or domain together, making it easy to process conversations in batches rather than scrolling through a chronological list. Spark also introduces a “Done Marker” for task-oriented email management. After replying to, archiving, or acting on a message, users can mark it as “Done.” The email then moves to a separate Done folder, keeping the main inbox clean and focused only on items that still require attention. This mimics a to-do list workflow right inside the mail client. Another recent addition is the integration of AI agents. Users can connect custom AI assistants to Spark to automate repetitive tasks—for example, drafting replies based on past conversation patterns, summarizing long email threads, or suggesting follow-up actions. These agents can be configured per user or per team, allowing granular control over automation. For organizing work more systematically, Spark provides smart folders and pinned conversations. Pinned emails stay at the top of the inbo
