What ActiveInbox is

ActiveInbox turns Gmail into a task manager for tracking important emails as tasks. It adds due dates, project folders, subtasks and notes, follow-ups, related emails, and a focus mode. Its workflow uses Gmail labels for due dates and projects, and those labels remain in Gmail if the extension is removed. Users can add an email to Google Calendar from the Due Date menu. The maker lists Chrome and Chrome-compatible browsers such as Edge and Brave; Firefox and Safari editions are unavailable. ActiveInbox is designed for a single user and does not support collaborative data sharing. The free plan allows deadlines on up to 10 emails at a time. Professional costs $5.37/mo (annual), and a 14-day trial is available. The maker says Gmail data travels between the user's computer and Google's servers, while email IDs, notes, and subtasks may be stored on ActiveInbox servers. Its privacy page says it complies with GDPR and allows users to request access to or deletion of personal information.
