Spark Mail review

Spark is a cross-platform email app from Readdle that connects any number of accounts, from Gmail and Outlook to other providers. The free plan covers Smart Inbox, unlimited email accounts, smart notifications, scheduled sends, snooze and a calendar, but no AI. Plus, at $8.25 per user a month billed yearly or $10 monthly, adds the Spark +AI assistant, 40 AI meeting notes, custom templates, team collaboration and productivity integrations. Pro, at $16.58 a month billed yearly or $20 monthly, adds Autopilot, Auto-Drafts, unlimited AI meeting notes, read statuses and a HubSpot integration. A subscription bought on one device works on Windows, Mac, iPhone and Android. AI usage, including meeting notes, draws from a monthly quota, so heavy users should watch the limit. Readdle offers a seven-day trial of Plus and Pro in the app. For people who want AI writing in a polished email app without paying $25 or more a month, Spark Plus is the cheapest route here.
