Spark Mail review

Spark Mail is the low-cost route to AI in a full email client. The free plan already sorts mail with Smart Inbox and connects unlimited accounts, so you can try the workflow before paying. Plus costs $8.25 per user per month billed annually ($99 per year) and turns on Spark +AI: a writing assistant that drafts, translates, summarizes and proofreads, quick AI replies, email summaries and an AI Assistant that can find and summarize emails, attachments, meeting notes and events across a year of history. Plus also includes 40 AI meeting notes a month. Pro at $16.58 billed annually adds the features busy inboxes want most: Auto-Drafts written in your voice, Autopilot rules that organize and forward mail, unlimited meeting notes and read statuses. AI features draw on a monthly quota, and Spark +AI must be switched on in settings. One subscription works across iOS, Android, Mac and Windows.
