See if they opened the email you sent from Gmail.

This Chrome extension shows you when it detects that a recipient opened your email. If it detects no opening, or the activity is uncertain, it tells you that too.

7 days free. No card. Private beta, by invitation.

What does each indicator mean?
Example: the emails you sent from Gmail.
Gmail
Your sent emails1–3
To: AlexYour project proposal — Here are the details…
To: JuliaA quick idea for your team — Hi Julia,
To: SamFollowing up on the proposal — About last week…
Hover over an eye or tap it to see the email’s status.

Simplified illustration with fictional messages. This demo does not track you.

OpenedNo opening detected?Uncertain

Three indicators show what happened to your email.

Green eye: opened
This tool detected an opening that passed its checks. It shows the time and, when available, an estimated opening count.
Gray eye: no opening detected
The email appears as “Not opened yet”. There is no opening to report. It may have been read without leaving a detectable signal.
?Eye with a question mark: uncertain
There was activity, but it could be automatic. This tool marks it as “Uncertain signal” instead of claiming the recipient opened it.

You sent the proposal.
Now you want to know if they opened it.

You spent time on the price, the message and the attachment. You hit send. And now you keep checking Gmail.

When this extension detects an opening, a green eye marked “Opened” appears beside that email. That is the moment you were waiting for. Try to leave the refresh button alone for a minute.

The activity helps you decide which proposal to revisit or when to follow up. An opening is a useful clue; it does not promise a reply or a sale.

Does another tracker mark your emails as “read”, but nobody replies?

You send a sales email. Your tracker says “Opened”. Then another opening. And another. But there is still no reply.

What did you send them? A proposal or a tax audit?

They may have read it and chosen not to reply. But some opening alerts are caused by software loading the email’s images, with no person reading the message. Even well-known trackers acknowledge these false alerts.

Email Open Tracker filters automatic loads it recognizes. When the activity is uncertain, it says so.

This tool could label every email “Opened”. It would give you a little thrill. It would not give you useful information.

No tracker detects every reading or avoids every mistake. This tool can also miss an opening or report one incorrectly.

Mailtrack’s explanation of false opening alerts

How to track an email in Gmail.

  1. Install the extension and connect with Google.The current beta requires an invitation. Request access to receive installation instructions.
  2. Write in Gmail and turn on Tracking.Then use Gmail’s usual Send button. Your recipient doesn’t install anything.
  3. Check the indicator beside your email.The extension also has a recent activity panel and a full list with search and filters.

For Gmail and Google Workspace in Chrome on a computer. Gmail must be in English or Spanish. There are no desktop notifications or automatic follow-up emails today.

When this tool can’t tell whether they read your email.

If the recipient uses Apple Mail’s privacy protection.

Apple can download an email’s images without the person opening it. That makes the download unsuitable as evidence of reading. This tool treats that signal as uncertain.

The mail app and its protection matter, not simply owning an iPhone. Apple’s explanation.

If no opening is detected, the reason is still unknown.

A gray eye can mean the email hasn’t been opened, images are blocked, or the message landed in spam. The inbox has a bouncer; a carefully written proposal can still be left outside.

Gray does not prove they ignored you. It does not prove the email reached spam, either.

If you send one email to several people, it can’t identify who opened it.

You email your partner’s family asking them to stop using that nickname. An opening appears. Your father-in-law? Your mother-in-law? The dog, handling correspondence?

This tool can report an opening of that shared email, but not name the recipient. Individual tracking generally needs a separate copy for each person. This extension does not split your message that way.

Other limits: Outlook, your own phone and forwarded emails

Outlook. Some detections carry “Exp.” because they are experimental and still under evaluation.

Your own phone. For recipients hosted by Google, opening your sent copy on another device can look like the recipient opening it. Forwards and quoted replies can also add activity.

This tool is new.
You can try it before trusting it.

It is in private beta. It does not have a long list of customer reviews to show you yet. It has a seven-day trial so you can judge what it does.

The stars will have to come from people who use it. Not the person designing this page.

What happens to your emails?

This tool does not upload message bodies or attachments. It stores tracked subjects, recipients and activity to show the history. You can export the data or delete your account from Settings.

Planned improvement: approximate opening location.

This feature is not available today and has no release date. Privacy tools can show a server’s location instead of the recipient’s. A location would only be useful when the signal supports it.
