The email tracker for Gmail that knows the moment your email is opened.
Green checkmarks in Gmail when your email gets read. No MailViewed branding on your messages, no robot opens in your numbers.
How to track emails in Gmail, in three steps.
Add the extension
One click from the Chrome Web Store, then sign in with Google. Setup takes under a minute.
Send from Gmail like always
Write and send as you normally do. A small pill in the compose window shows tracking is on.
Watch the opens land
Grey checks turn green in your sent folder, and your dashboard pings the moment each person opens.
Live email open tracking
Know the moment each person opens your email, with the exact time.
Read receipts in Gmail
Grey checks when it sends, green when it's read. Like iMessage, for email.
Robot filtering
Apple's privacy relay and corporate scanners get labeled as machines, so your open counts stay real.
Per-recipient detail
Send to five people and see exactly who opened, and when. A Pro feature.
Best time to send
See which send times get your emails opened fastest. A Pro feature.
Track from your phone
Compose on any device. It sends from your own Gmail and gets tracked.

More than a mail tracker for Gmail.
Every tracked email lives in one place: who opened, how many times, which opens were real people and which were machines. Add engagement scores, best send times, and live alerts, and you have full email tracking software running on top of your Gmail.

MailViewed never asks Google for permission to read your inbox, so it can't. From your message itself we keep exactly three things: the subject, who you sent it to, and when you sent it, plus the open and click events the tracker records. No message content, ever: not the body, not attachments, not even a preview. Your whole email stays in Gmail, where it belongs.
People check their sent folder a lot less now.
“I sent a proposal at 9:02 and watched it get opened at 9:14. Called at 9:20. Closed the deal that same week.”
“Setup took two minutes and then I forgot it was there. I email clients like always, the ticks turn green when they read, and nothing extra is added to my emails.”
“It flagged half of my old opens as machines. A humbling afternoon, but now when it says someone read my email, they actually did.”
Questions people actually ask.
Add the MailViewed Chrome extension, sign in with Google, and send email like you always do. Every tracked email gets grey checkmarks when it sends and green checkmarks the moment it gets read. Your dashboard shows who opened, when, and how many times.
MailViewed places a tiny invisible image in each email you track, unique to that message. When the recipient opens the email, their mail app loads the image and we record the open in real time. Automated scanners and privacy proxies load images too, so we filter those out instead of counting them as reads.
Yes. The Free plan is genuinely free, with no credit card: unlimited tracked emails, real time opens, read-receipt checkmarks in Gmail, bot filtering, and a live dashboard. A free plan with the essentials is here to stay as we grow. There is also an optional Pro plan (from $1.99/month, billed yearly) that adds extras like instant open alerts, per recipient detail, and full history, only if you want them.
Nothing visible changes in your email. MailViewed never adds its name, a badge, or any branding to your messages, on any plan. There is no “Sent with…” line at the bottom. That alone separates it from most Gmail trackers.
Only on some Google Workspace accounts, and only if the administrator turns them on and the recipient agrees to send one. Personal Gmail accounts have no read receipts at all. MailViewed adds read receipts to any Gmail account, with no Workspace admin setup needed.
No. We never ask Google for permission to read your mail, so we can't. The checkmarks are drawn locally in your own browser by matching your sent emails against the ones you tracked, and nothing from your inbox is ever sent to our servers. From your message itself we store only the subject, the recipient, and the send time: no body, no attachments, not even a preview.
Yes. Your dashboard works in any mobile browser, so you can watch opens from anywhere. You can also compose from your phone inside MailViewed: it sends through your own Gmail and gets tracked automatically.
