# HawkOpen > HawkOpen is an email, document and proposal tracking app made by TriStiX S.L. (Spain). It records tracking-image fetches, link clicks, replies and time spent on each PDF page, checks every event against more than 40 named rules (Apple Mail Privacy Protection, Gmail/Microsoft/Yahoo image proxies, security scanners, link previews, AI agents) and never presents a pixel request as proof that a person read a message. ## Key facts - Extension: separate builds for Chrome and Firefox 109+; the Chrome build is also intended for Edge, Brave and Opera. Works in Gmail, Outlook on the web and Yahoo Mail. - Campaigns: one copy per recipient, tracked only for recipients who agreed, up to 500 recipients per batch and 60,000 per month (Business). - Proposals: per-recipient link with email one-time code, time per page, forwarding detection, five client actions with Ed25519-signed, hash-chained receipts. - E-signature evidence report: SHA-256 document hash, hashed signer email, server time, Ed25519 seal, public verification page. ## Pages - [HawkOpen features: email, PDF, proposals and e-signature](https://hawkopen.com/en/features/): Email open and click tracking, PDF and proposal tracking, and a simple electronic signature.

We’ll show you what you’ll see. - [llms-full.txt](https://hawkopen.com/en/llms-full.txt) ## Limits - Tracking is off until the company’s owner or an administrator switches it on; then only recipients with a recorded consent are tracked (opens and links separately), and everyone else gets an ordinary email. A tracked email ends with “Do not track my activity”; every email ends with “Do not send me messages”. Time on document pages is measured only after the reader agrees on the page. - Verdicts are estimates (at most "likely"); only a recipient's own action such as a reply is certain. - PDF tracking, proposals, video and e-signature accept files only when the external malware-scanning pipeline is configured; otherwise uploads are refused. - The e-signature is a simple electronic signature (eIDAS), not advanced or qualified; the evidence report uses server time, not a qualified timestamp. - Gmail and Outlook connect through Google or Microsoft sign-in; Yahoo and other mailboxes through IMAP/SMTP. Reply detection covers IMAP/SMTP mailboxes. - Free plan: opens without a limit, link clicks in 10 emails a month, 7-day history, 1 mailbox. No public reviews or ratings yet. HawkOpen is in a controlled launch. ## Pricing - Free: €0, no time limit (opens without a limit, link clicks in 10 emails a month, 5 PDF links a month, 7-day history, 1 mailbox). - CRM on Free: a paid add-on with a 21-day trial (card required, up to 1,000 contacts), then €3 a month or €30 a year plus VAT, up to 5,000 contacts; cancel any time.
