How do I track who opened my HTML page?

Send it as an HTMLRadar link that asks each reader for their e-mail address, and you see who opened it, when, and how long they spent on each section. You get an e-mail the moment it is first opened, and there is no code to add to your page.

Example data. Choose a section.
Who opened the renewal proposal, and how long they spent on each section.

Three steps to a tracked link

  1. Drop the file.

    Open the HTML to link tool and drop your page: one .html file, up to 30 MB. Nothing is uploaded yet. If the page is already online, paste its address instead.

  2. Create an account, or sign in.

    The file uploads and HTMLRadar hosts it. Your file stays as it is: the reading is measured when the page is served.

  3. Ask for an e-mail, then send.

    On the document page, select New link. Under What readers do before it opens, choose Enter their e-mail and confirm it with a code, then select Create link and send it. Without that step you see that someone opened it, not who.

What you see for each reader

  • Who opened it, by the e-mail address they gave, and when. A reader who comes back shows up again.
  • An e-mail to you the moment the page is first opened.
  • How long they spent on each section. A section counts only once it has been at least half on screen for a continuous second, so scrolling past records nothing.
  • How far they scrolled, their device and browser, and their country and city.
  • A CSV download of all of it. On the free plan, the first five readers of each link are shown and readers after that are counted.

tom@yourclient.com just opened Renewal proposal.

One e-mail at the first open. Example data.

What is never recorded: what a reader types or where their mouse goes. There are no third-party trackers on the page, and readers’ network addresses are not stored.

What your readers see

Your page, on a link. If the link asks for an e-mail, the reader types it, and the code if you turned that on. Under the field is one line, “By continuing you accept HTMLRadar’s reader terms”, and a page with no gate ends with a link to the same terms, which set out what is recorded.

Pages on the free plan carry a small “Sent with HTMLRadar” line. Paid plans carry none.

What it cannot tell you

A code proves someone could open that mailbox when the page opened. It does not prove who sat in front of the screen afterwards.

A file sent as an attachment reports nothing, and a page on an ordinary web host counts visits without saying whose they were; only reads through the link count. A copy already sent as an attachment stays silent, so send the link from now on.

Common questions

Still have a question? hello@htmlradar.com

Can I see who opened an HTML file I sent as an attachment?

No. An attachment opens on the reader’s own computer and reports nothing back. Send the page as a link, and every open through that link is measured.

Do I need to add tracking code to my page?

No. HTMLRadar adds its own when it serves the page, and your file stays untouched.

Can I give each person their own link?

Yes. One page can have many links, one per person if you like, and each link keeps its own settings and its own list of readers.

Does the person who opens the page need an account?

No. Readers need no account and nothing to install. The page opens in any browser.

Is tracking who opened a page free?

Two tracked links are free, with no credit card. Unlimited links are $19 a month, or $190 a year.

Send your page as a link, and see who opened it.

Each reader by the address they gave, when they opened it, and how long they spent on each section.

Two tracked links, free. No credit card.

Sending inside a company? List your company’s domain on the link and turn on the code, so only colleagues get in.
