What It Is

DoubleTick is a Chrome extension for Gmail that lets you see whether your emails have been opened. The experience is very lightweight: you manually enable tracking when sending an email in Gmail, then check the Sent folder later. A gray single check means the email is being tracked but has not been opened, while blue double checks mean it has been opened—similar to WhatsApp-style status indicators.

Core Features and Integrations

The product centers on email open receipts, with features including instant desktop notifications, a pop-up dashboard, open counts, exact open times, and detection information from web and mobile clients. Its FAQ states that it records open events, timestamps, and device information via a tracking pixel, and supports desktop, mobile, and tablet environments. However, mechanisms such as Apple Mail Privacy Protection may reduce detection accuracy. For integrations, the site explicitly supports Gmail, its Chrome extension, and OpenClaw, allowing an AI agent to send tracked emails, check whether they have been opened, and list tracked messages.

Pricing and Ease of Use

Pricing is straightforward: the free plan is free forever, requires no credit card, and allows tracking 3 emails per week, including checkmark statuses, desktop notifications, and no watermark. Pro costs $0.99/month and includes unlimited tracking plus priority support. Given the feature set, Pro is inexpensive and suitable for frequent individual users. Setup is also simple: add the Chrome extension, open Gmail, let it configure the account automatically, and toggle tracking next to the send button.

Privacy, Security, and Limitations

DoubleTick clearly emphasizes that it does not read, store, or transmit email body content. It only stores the subject lines and recipient addresses of tracked emails, and tracking data is visible only to the user and not shared with third parties. This is a plus for users concerned about email content privacy. However, the page does not disclose information about team permissions, admin controls, audit logs, SSO, data residency, or compliance standards such as SOC 2/GDPR, so it should not be treated as an enterprise-grade email tracking platform by default.

Who It’s For and Access from China

DoubleTick is best suited for individual salespeople, business development, recruiters, freelancers, and small teams that need lightweight email follow-up—especially users who do not want a “Sent with...” branded footer in their emails. It is less suitable for large organizations that require multi-mailbox support, deep CRM workflows, team permissions, and compliance-oriented procurement. The page does not provide information about access from China. Since it depends on Gmail and a Chrome extension, users in mainland China should also consider Gmail availability, Chrome extension installation, and overseas subscription payment issues. Alternatives to compare include Mailtrack, Yesware, HubSpot Sales, Mixmax, and Streak.
