If you searched “Mailtrack” and landed on mailsuite.com, you’re not lost: Mailtrack rebranded to Mailsuite, and the old mailtrack.io address now redirects there. The extension is still the same double-check-mark read receipt for Gmail, just inside a bigger product. I installed and tested it, and here is exactly how to use Mailtrack email tracking — reading the check-marks, controlling it per email, and knowing where the free plan stops.
What Mailtrack Is in 2026
Mailtrack is an email-tracking extension for Gmail that tells you when your sent emails are opened, shown as a pair of check-marks next to each message. In 2026 it operates under the Mailsuite brand — mailtrack.io redirects to mailsuite.com — but the tracking extension still works exactly as before.
The first thing to clear up: per the Mailsuite homepage, the company “formerly known as Mailtrack” now markets itself as Mailsuite, and says the combined service is “trusted by more than 116,000 paying subscribers” and over 3 million users. So if a how-to tells you to visit mailtrack.io, that’s fine — you’ll land on mailsuite.com automatically.
What you’re installing is unchanged in spirit: a read-receipt layer for Gmail. Mailtrack’s whole idea is the double check-mark, borrowed from messaging apps — one check for sent, two for read — so you can glance at your sent folder and know whether an email landed. Around that sit real-time notifications, per-recipient tracking on group sends, follow-up reminders, and link tracking. If you’ve used Yesware or Boomerang’s tracking, Mailtrack is the lighter, read-receipt-first version of the same idea.
Install Mailtrack and Grant Access
Open mailsuite.com in Chrome, click Install for free, add the Mailtrack extension from the Chrome Web Store, reload Gmail, sign in with your Google account, and approve the permissions it requests. The check-marks and the Mailtrack toggle then appear on your emails.
Mailtrack on desktop is a Chrome extension, so step one is being in Chrome (or a Chromium browser that runs Chrome Web Store extensions). There are also Outlook and mobile apps, but Gmail-in-Chrome is the core flow.
- Go to mailsuite.com (or type the old mailtrack.io — it redirects) and click Install for free.
- Add the Mailtrack extension from the Chrome Web Store when prompted.
- Reload Gmail. The check-marks and the compose toggle don’t appear until you do.
- Sign in with the Google account you want to track from, and grant the Google permissions Mailtrack asks for. Without that grant, nothing tracks.
That last step trips people up — Mailtrack needs permission to see your sent mail and insert its tracking, and if you decline, the check-marks simply never show. If you’d rather not give a third party that access at all, a desktop client like Mailbird bundles tracking-style workflows inside the app instead of as a Gmail add-on.
Reading the Double Check-Marks
After you send a tracked email, one check-mark means it was sent and a second check-mark means the recipient opened it. Hover over the marks or open the Mailtrack panel to see the exact open time, how many times it was opened, and which links were clicked on paid plans.
This is the feature that made Mailtrack famous, and it’s deliberately familiar: it mirrors the read receipts you already know from chat apps. In your sent folder, each tracked email shows the check-marks inline, so you don’t open a dashboard to learn the basics — one check, it sent; two checks, they read it.
Click into the message or the Mailtrack panel and you get the detail: the timestamp of the first open, repeat opens (someone re-reading your proposal three times is a buying signal), and per-link clicks if you’ve enabled link tracking on a paid plan. Per the Mailsuite homepage, it also flags open spikes and “revival” alerts when an old email is reopened — useful for spotting when a dormant thread suddenly gets attention.
One honest note from testing: the marks update as the pixel loads, so a “sent but not read” state can simply mean the recipient hasn’t loaded images yet, not that they’re ignoring you. More on that limitation below.
Mailtrack (now Mailsuite) — install it free and watch the check-marks appear on your next sent email.
Turn Tracking On or Off per Email
Toggle the Mailtrack switch in Gmail’s compose window before sending. Leave it on to track that message, or switch it off for private emails where you don’t want a read receipt. The setting is per email, so tracking is something you choose message by message.
This is the control people most often miss, and it matters for both etiquette and privacy. Mailtrack adds a small toggle in the compose window. When it’s on, that email is tracked; flip it off and the message sends with no pixel and no check-marks.
Two times I always turn it off: personal emails to friends and family (a read receipt there is just creepy), and any message where I genuinely don’t care whether it’s been opened. For sales follow-ups, client updates, or anything where “did they see it?” changes my next move, I leave it on. Treating tracking as a deliberate per-message choice — not an always-on default — is the difference between a useful tool and a privacy liability. If you mostly want timing control rather than tracking, Gmail’s own schedule send covers that without any pixel at all.
Link Tracking, Reports, and Notifications
Link tracking logs which links a recipient clicks, daily reports summarize opens and clicks over time, and real-time notifications alert you the moment a tracked email is opened. Open tracking is free; link tracking is capped at 10 emails on the free plan and unlimited on Advanced.
Beyond the check-marks, Mailtrack stacks three layers worth knowing:
- Link tracking — instead of only “did they open it,” you see which links they clicked. Per the Mailsuite pricing page, the Free plan limits link tracking to 10 emails, while the Advanced plan makes it unlimited — so if click data matters to you, the free tier runs out fast.
- Reports — a recurring summary of your opens and clicks. The free plan offers daily reporting; Advanced adds weekly and monthly rollups, handy for spotting trends across a campaign rather than one email.
- Real-time notifications — desktop and email alerts the instant a tracked message is opened, per the Mailsuite email-tracking page. This is the one I find most useful: knowing a prospect just opened your email lets you follow up while you’re top of mind.
For high-volume sending, the Advanced plan also lifts the cap to 60,000 emails/month versus the free plan’s 100-email campaign limit — the line that pushes any real outreach user onto paid.

LinkedInWhere Tracking Breaks (and the Privacy Question)
Mailtrack relies on an invisible tracking pixel, so any recipient who blocks remote images, reads in plain text, or uses image-proxy privacy protection won’t register an open. A “not read” mark can be a false negative, not proof the email was ignored.
Every pixel-based tracker shares the same blind spot, and being honest about it saves you from bad decisions. Mailtrack registers an open when a tiny invisible image loads in the recipient’s email. If their client blocks remote images by default, opens the message in plain-text mode, or runs a privacy proxy that pre-loads or strips images, the pixel never fires — so you’ll see one check-mark even after they’ve read every word.
The practical rule: treat a second check-mark as strong evidence of an open, but treat the absence of one as inconclusive, never as “they ignored me.” I’ve followed up on “unread” emails plenty of times only to hear “yeah, I read that days ago.”
There’s also the etiquette side. Read receipts the recipient never agreed to can feel intrusive, and on the free plan a “Sent with Mailtrack”-style signature has historically told recipients you’re tracking them. Decide deliberately when tracking is appropriate — internal updates and cold outreach, sure; sensitive or personal threads, probably not.

Free vs Paid: Where the Limits Bite
The Free plan (€0/month) gives unlimited open tracking, link tracking on 10 emails, and 100-email campaigns. The Advanced plan (€9.99/month) unlocks unlimited link tracking, 60,000 emails/month, weekly and monthly reports, custom no-reply alerts, and priority support.
Here’s the line that decides it. From the Mailsuite pricing page, the two core tiers are:
- Free — €0/month. Unlimited Opened/Unopened tracking, scheduling, link tracking on 10 emails, a handful of PDF and video-message credits, and campaigns capped at 100 emails/month.
- Advanced — €9.99/month. Unlimited link tracking, 60,000 emails/month, custom no-reply alerts, daily/weekly/monthly reports, Zapier and CRM auto-BCC, and priority 24/7 support.
The free plan is genuinely usable if all you want is “did they open it” on individual emails — that’s unlimited and costs nothing. You hit the wall when you need click data at scale (the 10-email link cap) or you’re running real outreach (the 100-email campaign limit). At that point €9.99/month is the upgrade. Prices were confirmed on the Mailsuite pricing page as of June 2026.
If you’re comparing tracking tools rather than committing to Mailtrack, our Yesware review covers a heavier sales-focused alternative, and the Boomerang for Gmail guide covers tracking bundled with scheduling and follow-up.
Verdict
Best for: anyone who wants a simple, glanceable read receipt in Gmail and is fine with the pixel’s limits. Skip Mailtrack if you need bulletproof open data (no pixel tracker delivers that) or you’re uncomfortable tracking recipients without their knowledge.
Mailtrack — now Mailsuite — is still the cleanest, lowest-friction way to add read receipts to Gmail. The double check-mark is instantly understandable, the free plan covers basic open tracking without limits, and the per-email toggle gives you real control. It does exactly one thing well.
The caveats are inherent to the category: the tracking pixel can be blocked, so “unread” is never proof, and read receipts carry a privacy and etiquette cost you should weigh per message. The 10-email link-tracking cap and 100-email campaign limit also mean any serious outreach user lands on the €9.99/month Advanced plan quickly.
Best for: salespeople, recruiters, and founders who want a fast “did they open it?” signal inside Gmail. Skip Mailtrack if: you need guaranteed open data, or you’re tracking sensitive personal threads where a hidden pixel isn’t appropriate.

Prices confirmed on mailsuite.com/en/pricing as of June 2026.
What do the Mailtrack check-marks mean?
Mailtrack’s signature indicator is a pair of check-marks shown next to your sent email, modelled on a messaging app’s read receipts. A single check-mark means the message was sent; a second check-mark means the recipient opened it. It is the fastest way to see, at a glance in your sent folder, whether an email has been read without opening any dashboard.
How do I install Mailtrack for Gmail?
Go to mailsuite.com (it redirects from the old mailtrack.io address), click Install for free, and add the Mailtrack extension from the Chrome Web Store. Reload Gmail, sign in with your Google account, and approve the permissions it asks for. The check-marks and the Mailtrack toggle then appear on your emails and in the compose window.
Does Mailtrack add a signature to my emails?
On the free plan, Mailtrack has historically appended a small “Sent with Mailtrack” line to outgoing emails — a trade-off for the free tier. Recipients see it; you can keep it or, on a paid plan, remove it so your emails carry no Mailtrack branding. Check the current signature setting in the extension, as branding wording can change after the Mailsuite rebrand.
Why does Mailtrack sometimes not register an open?
Mailtrack works with a tracking pixel — a tiny invisible image. If the recipient’s email client blocks remote images, opens an email in plain-text mode, or uses privacy protection that pre-loads or strips images, the pixel never loads and no open is recorded. Treat read receipts as a strong signal, not absolute proof, and never assume an unopened mark means the person definitely hasn’t read it.
Is Mailtrack the same as Mailsuite now?
Yes. Mailtrack rebranded to Mailsuite, and mailtrack.io now redirects to mailsuite.com. The email-tracking extension you install is still commonly called Mailtrack and works the same way, but it now sits inside the broader Mailsuite product, which Mailsuite says is trusted by more than 116,000 paying subscribers and over 3 million users.
