Side-by-side comparison of Mailtrack and Streak email tracking in Gmail, showing read-receipt checkmarks against a CRM pipeline view

The short answer

For open tracking alone, Mailtrack — now part of Mailsuite — is the better pick: it is purpose-built, works on Gmail and Outlook, and documents how it filters false opens. Choose Streak if tracking is a side effect of running deals in a Gmail CRM. Both rely on a pixel, so both undercount.

The honest version of Mailtrack vs Streak for email tracking is that you are not comparing two trackers. You are comparing a purpose-built read-receipt tool with a Gmail CRM that happens to include tracking as one of its free power tools.

That difference decides almost everything: how much detail you get per open, what else lands in your Gmail sidebar, and whether you end up paying for pipeline features you never wanted. This comparison scores tracking specifically, and it names a winner per dimension rather than declaring one tool better overall.

Everything below was checked against each vendor's own live pages in September 2026. Capabilities and packaging change without notice, so verify anything that matters to you on the vendor's page before you install.

Worth checking the specifics yourself before you commit — the details below are what actually decide it.

The verdict up front#

If the job is knowing whether your Gmail messages were opened, Mailtrack is the better install. It is built for exactly that, it ships an Outlook add-in as well as the Gmail extension, and it is the only one of the two that publicly describes filtering out automated opens from scanners and image prefetching.

If tracking is something you want attached to a deal record rather than a checkmark in your inbox, Streak is the better install — and this is a real concession, not a courtesy one. Streak's tracking is worse at being a tracker and much better at being evidence inside a pipeline, with shared email history, mail-merge reporting and a team-visible record of every touch.

Streak also wins one thing outright that people usually discover after installing: its free email tools do not append a promotional line to your outgoing mail. Mailtrack's free tier does, and for anyone emailing clients or investors that single detail settles the choice.

Mailtrack is now part of Mailsuite

As of September 2026, mailtrack.io redirects to mailsuite.com, and the vendor's FAQ states Mailtrack has been part of Mailsuite since 2024. The Outlook add-in and the free-plan email signature are both Mailsuite-branded. Older reviews describing an independent Mailtrack product are out of date — check what you are actually installing.

Where Mailtrack wins#

Mailtrack wins on being a tracker and nothing else. The signal lives where you already look — a single check for delivered, a second check when the message is opened — so there is no second surface to check and no pipeline to maintain.

It also wins on reach. The download menu lists a Chrome extension, an iPhone app, an Android app, an official Gmail add-on, an organisation-wide Workspace deployment and a Mailsuite add-in for Outlook. Streak's site names Chrome, Safari and Edge, and does not mention Outlook at all. If half your team lives in Outlook, this is not a close call.

  • Per-recipient attribution on group emails is stated plainly — you see which person opened, not just that someone did.
  • Alert types go beyond the first open: no-reply alerts, multiple-open alerts, and alerts when an old thread is reopened.
  • Link click tracking, a custom link domain on higher tiers, and tracked buttons inside the message body.
  • An activity dashboard and a recurring activity report, so tracking data is reviewable rather than only interruptive.
  • Adjacent tools most trackers skip: document and PDF tracking with per-page timing, e-signature requests, and email templates.

The accuracy claim that actually differentiates them#

Mailtrack is the only one of the two that makes a public accuracy argument. Its pages say it discards your own opens and filters automated opens caused by mail scanners and image prefetching, and it markets this as a verification layer rather than a raw pixel counter.

That matters because the most common way a read receipt lies is a false positive: a security gateway or a mail client prefetches the image, and you get a green check for a message no human has looked at. A tracker that filters those is giving you a cleaner signal, and Mailtrack is the one claiming to do it.

Streak makes no equivalent claim on any marketing page. Its support article simply explains that a pixel is inserted and that the amount of information received varies by the recipient's settings, mail program and device. That is candid, but it is not the same as filtering.

Where Streak wins#

Streak wins the moment tracking stops being the point. An open is only useful if it changes what you do next, and Streak is built so the open lands next to the deal, the contact and the whole thread history your team can see.

It also wins on the free tier in a way that catches people out. Streak's free email power tools — tracking, link tracking, snippets, a capped daily mail merge, thread splitter and shareable thread links — are offered without a promotional signature on your outgoing mail. Mailtrack's own pages state that free accounts send with a 'Sent with Mailsuite' footer, removable on a paid tier. If you are emailing a client, a candidate or an investor, a vendor's advert in your signature is not a small cosmetic issue.

  • Opens are attached to a pipeline record, so a stalled deal is visible as a stage and a date rather than a notification you scrolled past.
  • Mail merge reporting is per recipient, with last-view date, click, reply and unsubscribe status across a campaign.
  • Follow-up sequences pause automatically when someone replies, which is the part manual follow-up always gets wrong.
  • Automatic email sharing gives the team the full correspondence history per contact, plus duplicate-outreach warnings.
  • You can mass-email only the people who opened your previous message — tracking feeding directly into the next send.
  • Native iOS, iPad and Android apps, so the record is not stranded on a desktop browser.

What a green checkmark actually proves#

Both tools work the same way underneath, and both say so. A small invisible image is embedded in your outgoing message; when the recipient's mail client requests that image from the vendor's server, the open is recorded. There is no other mechanism, and no vendor has a private one.

That single fact sets a ceiling on accuracy that no feature list can raise. Streak's support documentation puts it in one sentence: if the pixel is never loaded, it receives no information at all. Not a maybe, not a partial — nothing.

So a tracked message has three possible states, and only one of them is what people assume they are getting.

What you seeWhat it might actually meanHow often this bites
No open recordedThey read it with images off, in a text preview, or behind a privacy proxy that never fetched your pixelThe common failure — silence is not evidence of anything
Opened, onceA human read it, or a scanner, prefetcher or privacy proxy loaded the image on their behalfFrequent enough that Mailtrack markets filtering for it
Opened, many timesGenuine re-reading, or one client re-rendering the same message repeatedlyWhy 'they opened it five times' is a weak buying signal

Neither vendor's marketing addresses image blocking

Checked September 2026: Mailtrack's pages discuss filtering false positives but never mention recipients blocking images, and Streak's marketing pages make no accuracy claim at all — the caveat appears only in a support article. Apple's Mail Privacy Protection, which Apple Mail users are prompted to enable during setup, routes remote images through a proxy and can load them without anyone reading the message. Corporate gateways do the same. Treat every open figure as a floor, never a count.

So is open tracking still worth installing?#

Yes, with the expectations reset. Tracking is useful as a directional signal on a single thread — did this specific proposal to this specific person get looked at before I chase it — and close to useless as a metric you average, report on, or make a forecast from.

The practical rule: act on an open, never on the absence of one. An open tells you a follow-up is likely to land. Silence tells you nothing at all, because you cannot distinguish 'ignored' from 'read with images off'.

Gmail-to-Gmail is the best case for both tools, because Gmail loads remote images by default through its own proxy. Recipients on Apple Mail with privacy protection enabled, on a locked-down corporate gateway, or on a client with images off are where both products go quiet — identically, since the mechanism is identical.

The recipient did not agree to this

Open tracking is legal in most jurisdictions for one-to-one business email, but it is personal-data collection under GDPR-style regimes, and a recipient who discovers a pixel usually experiences it as surveillance rather than diligence. Be careful with tracking on internal mail, on sensitive threads, and in any region where you would need a lawful basis. If you would not say 'I can see you opened this' out loud, do not track it.

How each one is packaged#

Shapes only here — no figures. Both vendors change pricing, and any number in a blog post is stale within a quarter. Check the vendor's own pricing page before you buy.

Mailtrack is packaged as a free tier plus two higher tiers, with a separate contact-sales route for teams and organisations. Tracking itself is unlimited on every tier; what the paid tiers actually sell is depth and polish — how far back your tracking history goes, per-recipient attribution on group email, how many emails get click tracking, custom alerting, a custom link domain, and removal of the promotional footer.

Streak is packaged as free email power tools plus three named paid tiers — Pro, Pro+ and Enterprise — billed per user per month, with an annual discount and a time-limited trial on the popular tier. Tracking sits in the free tools; the paid tiers sell the CRM. Note that some integrations and automations are excluded from the entry paid tier rather than merely limited, which is easy to miss.

Read that difference carefully, because it drives the real cost. With Mailtrack you pay to make tracking better. With Streak you pay for a CRM and the tracking comes along regardless — so if you will never build a pipeline, Streak's free tools may be all you ever need from it.

Who each is genuinely for#

The choice is less about features than about which artefact you want an open to become: a checkmark, or a row in a pipeline.

A third option, honestly#

There is a version of this problem where neither answer is a tracker. Most people install one of these because a thread went quiet and they want to know whether to chase it. Tracking answers that with an inference about an image request. The stronger signal was always sitting in the inbox: whether a reply came back, and how long ago.

That is the job AI Emaily does, and we should be straight about the limits before anything else. We build AI Emaily, and we do not ship open tracking. We are not going to bolt a pixel on to make this comparison come out in our favour — the mechanism has the ceiling described above no matter whose logo is on it.

What we do instead is close the loop without the pixel. AI Emaily triages every account you connect — Gmail, Outlook and IMAP in one place — and surfaces the threads where you are the one waiting on a reply, with how long it has been. It drafts the follow-up from a Personal Context brain and per-client profiles you set yourself, never by mining your sent mail, and in Copilot mode nothing leaves your outbox without your approval, with undo and an audit trail behind it.

That is a different answer to the same question, and it is honestly worse than Mailtrack at one specific thing: it will never tell you a message was opened but not replied to. If that exact distinction is what you are buying, install Mailtrack. If what you actually need is to stop losing threads you are waiting on, start at aiemaily.com and the plan details are on /pricing. There is a 7-day free trial on Pro and Autopilot — card required, and nothing is charged if you cancel before day seven.
