Mixmax vs TrackMailBox

Mixmax is a sales engagement platform for revenue teams using Gmail or Outlook. It runs as a Chrome extension for Gmail, an Outlook add-in, and a web dashboard for sequences, reports, and workspace settings. Multi-stage sequences can send follow-up emails, create tasks, and schedule calls using merge variables and CSV uploads. Real-time email open and click tracking comes with desktop notifications, while scheduling links let recipients choose a time and add the meeting to both calendars. Rules can create Salesforce tasks after emails are opened or add recipients to sequences when deal stages change. Mixmax also syncs email, meeting, and sequence activity to Salesforce or HubSpot, and lists more than 40 native integrations included on every plan. The Free plan allows 20 tracked emails and up to 50 sequence recipients per month. Paid plans start at $29/user/mo billed annually; a 14-day trial is available. Mixmax requires Chrome for its extension and may limit one user's sending to 1,000 emails per day.

TrackMailBox is a free Chrome extension for Gmail and Google Workspace that tracks email opens and link clicks. It records whether recipients open messages, how many times, and which tracked links they select, with real-time desktop notifications for both events. Gmail’s Sent folder displays Opened, Clicked, Unopened, and Untracked badges. Scheduled Gmail messages receive tracking automatically. A Best Time calendar analyzes engagement patterns across regions and time zones to suggest sending hours. Users can create, search, manage, and insert templates containing subject lines and body text from Gmail’s compose window. The Free Forever plan costs nothing, billed forever, and lists unlimited email tracking, open history, link tracking, notifications, a detailed analytics dashboard, Chrome extension access, and 24/7 email support. Opens use an invisible 1x1 pixel; tracked links redirect through TrackMailBox servers. The privacy policy says email bodies are not stored, while data transmission and database connections are encrypted and access-controlled. Corporate firewalls may block pixels, and tracking can be delayed.
