Trackerjacker Pro puts per-recipient open tracking and PDF Fill & Sign right inside Gmail — privacy-first, with no dashboards to learn.
Each recipient gets a unique pixel, so a group send tells you exactly who read it, when, and how many times — not just that someone did.
Open a PDF attachment, fill and sign it, and reply — without leaving Gmail. Documents pass through encrypted storage and are deleted within seconds.
Your own Sent copy carries a decoy pixel, so re-reading your own email never counts as an open. The data is the recipient's, not yours.
A monochrome skin and a tracking toggle sit right in the compose window. Nothing new to learn — it's the Gmail you already use.
Open-source core, per-user isolation, short-lived document storage, and a published data-flow you can hand to a security team.
Delivery over Gmail's own SMTP with XOAUTH2 — the same mechanism the incumbents use, not a fragile workaround.
A focused popup shows your recent tracked emails and per-recipient opens at a glance — the same monochrome language as the in-Gmail UI.
Trackerjacker handles your email and documents, so we're finishing an independent CASA Tier-2 security assessment and a SOC 2 data-compliance review first. Join the waitlist and we'll email your install link the moment it's verified.
Each email embeds a tiny invisible image hosted on our infrastructure. When a recipient's mail client loads it, we record the open. Per-recipient URLs let us attribute opens individually.
Like all pixel tracking, it can't see opens where images are blocked (Apple Mail Privacy Protection, some corporate scanners). We never claim more than the pixel can prove, and we suppress your own self-opens.
Fill & Sign PDFs are read from your own Gmail, stored encrypted for the seconds it takes you to sign, then deleted — automatically and within 24h at the absolute latest. The full data-flow is on the Privacy page.
Trackerjacker handles your email and documents, so before public release we're completing an independent CASA Tier-2 security assessment, a SOC 2 data-compliance review, and Google's OAuth verification for the restricted Gmail scope. We'd rather launch verified than fast.
Join the waitlist with the Gmail address you send from. We'll email the install link the moment the Chrome Web Store listing is live and verified — no scary 'unverified app' warnings.
