Spark +AI review
A broad AI email toolkit across four platforms, with paid AI features starting at $10 per user monthly.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Spark +AI is the AI feature set within Readdle’s Spark email client, aimed at individuals and teams who want help with routine email work. It covers drafting and quick replies, proofreading, rewriting, tone adjustment, translation, and summaries in short, detailed, or action-point styles. Inbox classification separates personal email, newsletters, and notifications, while follow-up reminders help track messages that need another response. The application is available on macOS, Windows, iOS, and Android, and Spark supports Gmail, Google Workspace, Outlook, Office 365, Exchange Online, iCloud, Yahoo, and standard IMAP accounts.
The plan structure makes the boundary between basic email and AI assistance important. Free includes Smart Inbox, unlimited email accounts, Smart Notifications, and Calendar. Plus costs $10 per user per month and lists Spark +AI, AI Assistant, 40 AI Meeting Notes, and Team Collaboration. Pro costs $20 per user per month and adds unlimited AI Meeting Notes, Advanced Team Collaboration, HubSpot integration, and Spark CLI with triage access. Enterprise highlights security and controls, a Dedicated Success Manager, and productivity coaching. A 7-day free trial is available. Buyers who primarily want the AI tools should compare Plus with Pro based on meeting-note volume and the additional Pro features.
The AI Assistant can search across emails, attachments, calendar data, and meeting notes, making the feature set broader than drafting alone. Its supported actions include summaries and help with email, but drafting does not mean unattended sending: the writing workflow describes drafts for review, editing, and sending by the user. That distinction matters for teams looking for automated outbound email. Spark +AI is a fit for people who want assistance across several email tasks in a single client and are comfortable reviewing drafts; those seeking automatic sending without approval should look elsewhere.
