Mailbutler review

Mailbutler is an inbox extension that covers Apple Mail, Gmail and Outlook, which makes it one of the few trackers for reps who work in Apple Mail. Every plan includes basic tracking, which shows when an email was first opened and a link first clicked, with real-time notifications on desktop and mobile. The Smart plan, at $11 per user per month billed yearly or $14 monthly, is where it becomes a sales tracker: it keeps a full history of opens and clicks, shows device and location, tracks each recipient separately on group emails, and sorts tracked emails into high, medium and low urgency for follow-up, with an AI assistant that drafts the reply. Business at $24 billed yearly adds a custom tracking subdomain, IP blacklisting so coworkers' opens are ignored, and a sync of tracking events to a CRM. Starter at $4 is cheap but limited to first opens. The 14-day trial includes every feature and needs no card.
