Spark Mail
Spark Mail is an email app for Android, iOS, macOS, and Windows that helps users focus on important messages.

AI is disabled by default, and AI features have plan-based monthly quotas. Listed integrations include Asana, Evernote, Google Drive, Microsoft Teams, Notion, Slack, Todoist, Trello, and Zoom, with availability varying by platform. The free plan includes unlimited accounts, Smart Inbox, Smart Notifications, essential email productivity, and Calendar. Plus costs $10 a month per user, and Pro costs $20 a month per user. A 7-day Plus and Pro trial is available when subscribed to directly in the app.
