For recipients who agreed to tracking, HawkOpen shows whether a proposal, PDF or email campaign was likely opened by a person or by a scanner. It reminds you when a client goes quiet, measures, with the client’s consent, the time spent on each page of a document and lets clients accept and sign a proposal in the browser. It works with Gmail, Outlook and any IMAP mailbox.
On the right is what an ordinary open counter shows. Move the slider to the right and HawkOpen rates each of those events: the person comes forward, and the noise fades into the background.

Looks like a lot of interest.
HawkOpen
Probably one person opened the email. That’s who you call.
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.
If the client agreed to tracking, HawkOpen shows whether your proposal was likely opened by a person or only by a security scanner or Apple Mail’s servers: every open gets a category and the code of the rule that classified it.
Ordinary tools say “opened 6 times”, even though machines made half of those opens: Apple Mail fetches images in advance, and security filters click links before a person does. You call at the wrong moment, or not at all.
HawkOpen checks every event against more than 40 named rules and shows where each one came from: likely a person, a proxy, a scanner or you yourself.
You count only what a person did, and the history shows the reason behind every verdict.
You know when the proposal reached a person, not a scanner.
Set a reminder in HawkOpen when you send: if the client doesn’t reply within the time you choose, HawkOpen lets you know, and if they reply, the reminder disappears (Pro and Business plans).
Once the proposal is sent, the guessing starts: follow up tomorrow or next week? Too early looks pushy; too late and the client picks someone else.
You set a reminder when you send. If no reply arrives within the time you chose, HawkOpen tells you: it never sends anything to the client on your behalf. When the client replies, the reminder disappears.
On the Pro and Business plans, HawkOpen detects replies in IMAP/SMTP mailboxes.
The reminder arrives on its own when nobody replies.
Send the PDF as a HawkOpen link instead of an attachment: you’ll see whether someone else opened the link and, if the client agrees on the page, how long they spent on each page.
An email attachment disappears from view. You don’t know whether anyone opened it, how much they read or whether they forwarded it to their manager.
Instead of an attachment, you send a link to the PDF. HawkOpen measures the time on each page (once the client agrees on the page) and shows when someone else opens the link.
We accept files only after antivirus scanning; this feature works when scanning is switched on.
With the client’s consent, you see the time spent on every page of the document.
With HawkOpen, the client accepts and signs your proposal in the browser after confirming their identity with a code sent by email; every action gets a signed receipt, and the signature is a simple electronic signature (eIDAS).
Printing, scanning and sending back takes days, and the proposal goes cold in the client’s inbox.
The client gets their own link with a one-time code. They can accept the proposal, book a meeting, ask a question, fill in a form or confirm receipt. Every action gets a signed receipt.
The signature is a simple electronic signature (eIDAS), not a qualified one. The evidence report describes what it confirms and what it does not.
The client accepts and signs the proposal in the browser.
False opens come from Apple Mail Privacy Protection, image proxies and security scanners; HawkOpen identifies them with more than 40 named rules and separates them from opens likely made by a person.
Since Apple Mail started fetching images in advance and companies started scanning every link, an “open” in an ordinary counter often has nothing to do with a person.
HawkOpen checks every event against more than 40 named rules: Apple Mail Privacy Protection, the Gmail, Microsoft and Yahoo image proxies, security scanners, link previews and AI agents.
Instead of one number, you see categories and the reason for each verdict. The top verdict is “likely a person”, because only the recipient’s own action, such as a reply, is certain.
You separate people from Apple Mail, proxies and scanners.
HawkOpen sends a separate copy of your campaign to each recipient (up to 500 per batch on the Business plan), tracked for those who agreed to tracking, and separates scanner clicks from human clicks, so you know who to call.
In campaigns, scanners can “click” every link, so the results look great and nobody calls. You don’t know who is worth contacting.
HawkOpen sends a separate copy to each recipient, so events are matched to the right person. Scanner clicks are kept apart from human clicks.
Results go to your contacts in the CRM and into weekly and monthly reports.
Every recipient gets a separate email, tracked if they agreed.
HawkOpen records every client action on a proposal with the server time, a hash of the document and an Ed25519 signature that anyone can check on a public verification page.
A month later, the client remembers it differently: they never got the proposal, never accepted that version, didn’t know about the deadline. A screenshot of an email settles nothing.
HawkOpen records every client action on the proposal with the server time, a hash of the document and an Ed25519 digital signature. The public keys are published, and the receipt can be checked on the verification page.
This is electronic evidence with clearly described limits, not a qualified trust service.
Every client action has a signed receipt.
Sign in with your Google or Microsoft account, or connect any IMAP/SMTP mailbox. Add the extension to Chrome or Firefox.
Write in Gmail or Outlook in the browser. HawkOpen adds tracking separately for each recipient who agreed to it, once your company’s owner or administrator has switched tracking on. You send a proposal or PDF as a link.
The dashboard shows who read, for how long and what they clicked. Reminders tell you who to contact.

HawkOpen tracks a client only after their consent is recorded, and every tracked email has a short notice in the footer with the link “Do not track my activity”. Tracking is a technical signal and we present it as one: we don’t claim that an open proves the email was read.
It works not only in Gmail and Chrome, but also in Outlook, Yahoo and IMAP mailboxes, and in Firefox. For every open it shows a category and a rule code, and it also tracks time on PDF pages (with the reader’s consent) and proposals with acceptance.
