HawkOpen features
Email, PDF and proposal tracking that rates every event. Messages, documents and event history in one place.
Illustration with sample data
Message history
Choose who you are and click a problem. The scene shows a day with HawkOpen: noise from scanners and mail servers fades into the background, and what a person did comes to the front.
You know when the proposal reached a person, not a scanner.
Apple Mail, image proxies and antivirus filters are labelled separately.
The reminder arrives on its own when nobody replies.
No calendar to watch, and no following up too early.
With the client’s consent, you see the time spent on every page of the document.
You know whether the client read the pricing or just the cover.
The client accepts and signs the proposal in the browser.
A simple electronic signature with an evidence report.
You know whether anyone saw your application at all.
And when it’s a good time to ask about a reply.
You see whether someone opened your complaint or application, if they agreed to tracking.
It is a technical signal, not an official proof of receipt.
You know who keeps coming back to your message.
Selling a car, renting out a flat, a job for a tradesperson.
You see which pages of the document someone viewed.
A rental agreement, a renovation quote, loan documents.
The extension removes tracking pixels from the emails you read.
Protection works in Gmail, Outlook and Yahoo Mail in the browser.
Sample events. An open is a technical signal, not proof that someone read your email; HawkOpen shows where it came from.
A person, Apple Mail, a proxy or a scanner: every event shows the code of the rule that classified it.
Even on the free plan, you see every open with its verdict, with no limit.
Gmail, Outlook, Yahoo and any IMAP mailbox. Chrome, Edge, Brave, Opera and Firefox.
Time on PDF pages, proposal acceptance and a simple electronic signature in one tool.
HawkOpen tracks only recipients who agreed. Every tracked email has a notice in the footer with the link “Do not track my activity”, and the recipient can also refuse tracking in their own portal.
The extension removes tracking pixels from the emails you receive.
Check what happens after you send a message. See each event’s category and the reason for it.
Image fetchPrivacy proxy
Resource fetched by an intermediary.
Link clickSecurity scanner
Link opened in an analysis environment.
Link clickLikely human
Behaviour consistent with an end user (browser, interaction).
Event. Rating. Reason.
A document shared as a link. Session history and time on each page.
Preview of the signing flow and its history. Availability to be confirmed.
Each tracking-image fetch is checked against named rules for Apple Mail Privacy Protection, mail-provider proxies, security scanners and link previews, and shown with its rule codes.
Campaign and dashboard sends create a separate delivery and opaque token per recipient; one group message is never presented as reliable individual attribution.
Tracked-link requests are separated into likely-human and scanner or bot activity before they affect priority alerts or KPIs.
Connect Gmail and Outlook with your Google or Microsoft login, or Yahoo and any other mailbox through IMAP/SMTP, and track from all of them.
Separate builds for Chrome and Firefox; the Chrome build is also intended for Edge, Brave and Opera. Works in Gmail, Outlook on the web and Yahoo Mail.
Send campaigns to up to 500 manually selected or saved-list recipients per batch; each recipient who agreed to tracking gets an individual token.
Preview only: production upload remains unavailable until malware scanning and document sanitization are configured.
Preview only: production upload remains unavailable until malware scanning and isolated transcoding are configured.
A simple, non-qualified electronic-signature workflow with an Evidence Report that states its limitations; secure document ingestion is required first.
Scanner-safe confirmation polls, reusable email templates and follow-up reminders when a reply never arrives.
Review per-contact message counts and classified open, click and reply activity with notes.
Weekly and monthly email reports about your sending activity.
A note on accuracy: HawkOpen records tracking-pixel and tracked-link requests as technical signals. Apple Mail Privacy Protection, image proxies, caching, bots and security scanners can cause false or ambiguous events.
Sign up, connect Gmail or Outlook with your Google or Microsoft login, or any IMAP/SMTP mailbox, and add the HawkOpen extension to Chrome or Firefox.
Write in Gmail, Outlook on the web or Yahoo Mail; the extension adds a tracking token for a single recipient. For several recipients, send from the HawkOpen dashboard or a campaign so each person gets their own token. Tracking works once your company’s owner or administrator has switched it on, and only for recipients whose consent is recorded; others get an ordinary email.
Every image fetch, click and reply appears with a category and the rule codes behind it, so you do not follow up because of a security scanner.
Designed for controlled verification. Public production launch still requires the release gates listed in the readiness report.
HawkOpen is an email, document and proposal tracking app from TriStiX S.L., a company in Spain. It records replies and, for recipients who agreed to tracking, tracking-image fetches, clicks and time spent on each page of a PDF, checks every event against more than 40 named rules and never presents a pixel request as proof that someone read your message.
A tracker counts a fetched image. HawkOpen tells you who most likely fetched it.
Apple Mail Privacy Protection fetches images in advance
Nobody may have read the email yet
Gmail, Microsoft or Yahoo fetch the image through their servers
Often close to a real open, but not proof
Proofpoint, Mimecast, Barracuda or Safe Links check links in seconds
Not a person: ignore it for follow-ups
No machine rule matched
Maybe a person, maybe an unknown program
A click from a visible browser tab on a home or office network
Still an estimate; only a reply is certain

Checkout shows the total with the VAT of your billing address before you pay. VAT rates checked on 12 November 2026. Stripe calculates the final amount from your billing address.
Prices are net. VAT is added according to the country of your billing address: consumers see the price including the VAT of their country before they pay, and Stripe calculates the final amount from the billing address. A business enters its EU VAT number in the HawkOpen panel before buying; we check it in VIES and pass only a valid number to Stripe, so a valid number means the net price under the reverse charge (art. 196 of Directive 2006/112/EC) straight away. If VIES says the number is invalid or does not answer, the purchase is made with VAT; once the number is confirmed, later invoices are without VAT. The first invoice is not corrected automatically: you can ask for a correction through help in the panel. Businesses in Spain pay Spanish VAT. Consumers may withdraw within 14 days.
Current plan catalogue. Checkout availability and the final quote are confirmed in the application. Built for controlled verification.
Application secrets use authenticated AES-256-GCM encryption. Tenant isolation is currently enforced in application code; PostgreSQL RLS, production key management and an independent assessment remain release gates and are not presented as completed certifications.
HawkOpen charges €1 + VAT now for the first 20 days. From day 21, Business continues with yearly billing at €90 a year plus VAT and renews every year until canceled. You can choose monthly billing at €11/month instead. Cancel during Intro to prevent renewal. Mandatory withdrawal and refund rights remain unaffected.
Gmail and Outlook connect through your Google or Microsoft login; Yahoo and other mailboxes connect through IMAP/SMTP. HawkOpen is in a controlled launch, so each provider connection is verified before it is offered in production.
There are extension builds for Chrome and for Firefox 109 or later. The Chrome build is also intended for Edge, Brave and Opera. It works in Gmail, Outlook on the web and Yahoo Mail.
Once your company’s owner or administrator has switched tracking on, HawkOpen adds a unique 1×1 image URL for each recipient whose consent to tracking is recorded; others get an ordinary email. When that URL is requested, HawkOpen records and classifies a technical open signal. It may come from a person, privacy proxy, scanner or unknown client; it is not proof of reading.
Tracking-pixel and tracked-link requests are technical signals. Apple Mail Privacy Protection, image proxies, caching, bots and security scanners can cause false or ambiguous events.
HawkOpen supports a simple, non-qualified electronic-signature process with an audit trail and Evidence Report. Electronic evidence may have legal effect, but this does not establish equivalence with a handwritten or qualified signature or suitability for every legal act. Applicable law and form requirements must be assessed for each use.
Yes. Cancellation is scheduled for the end of the paid period; during Intro it prevents renewal on day 21. No voluntary refunds are offered after a service period begins, except where mandatory law or an applicable withdrawal right requires otherwise.
Yes. The tracking image is not visible, but every tracked email ends with the notice “This message contains HawkOpen tracking elements.” and the link “Do not track my activity”, with which the recipient refuses tracking by that company. HawkOpen tracks only recipients whose consent is recorded, and that link lets them withdraw it later. Every email, tracked or not, also ends with “Do not send me messages”.
