Email Tracking Software: Six Tools, Priced and Capped

The best email tracking software for a B2B seller is almost always the one already bundled into the tool the mail leaves from, because the tracking layer is mechanically identical across every product in the category and the only things that genuinely differ are the cap on the free tier and the price of removing it. What separates these six is not accuracy. It is how long each one keeps the history, how many messages it will watch before asking for money, and whether the open it reports is worth acting on at all.

That last question has changed the category more than any feature release. Apple's own iPhone User Guide states the position plainly for every Apple Mail user with the setting on: "It also prevents senders from seeing if you’ve opened the email message they sent you," as published by support.apple.com on 2 September 2026. Google's Gmail help page offers its users the settings "Always display external images" and "Ask before displaying external images," published on support.google.com and fetched the same day. Between them, a large and unmeasurable share of your recipients either cannot generate an open event or has been asked whether to.

So the buying question is narrower than the listicles make it. You are choosing a notification tool whose strongest signal is the link click, priced per seat, and the sensible move is to spend as little as possible on it.

What every one of these tools does, identically

There is no proprietary tracking technology in this category. Two mechanisms exist and every product uses both.

The first is a one pixel image hosted on the vendor's domain with a unique identifier in its URL. When a mail client requests that image, the vendor records an open. The second is link rewriting: every URL in the body is replaced with a redirect through the vendor's host, so a click can be recorded before the reader lands on the destination.

That is the whole technology. A vendor cannot be more accurate than another at recording a request that was never made, which is why accuracy claims in this category are rarer than they are in verification, where vendors at least have something to be accurate about.

OpenWeakest

• Fires when a remote image is fetched
• A preloading client or a security scanner fetches it with no human present
• Apple's Mail Privacy Protection suppresses it entirely for users who turn it on
• Gmail offers a setting to ask before loading images at all

Link clickStronger

• Requires a deliberate action on a specific link
• Names which piece of content was chosen
• Still forgeable by link-scanning security software
• The event worth building a workflow on, if any is

Attachment or document viewMost specific

• Requires opening a document, which is a real decision
• Rare enough that a single event is worth reading
• Usually the feature gated behind the paid tier
• Carries page-level detail on some products

The six, and what each vendor's own page publishes

Every figure below was read off the vendor's own pricing page from a snapshot taken on 2 September 2026. Where a page did not serve a figure to that fetch, this says so rather than borrowing a number from somewhere else. Prices move, and an undated price is a claim that rots.

Streak

Streak's pricing page carries a block headed "Use our email power tools for free, forever" and lists "Email & Link Tracking" inside it, alongside snippets, "Mail Merge (50/day)", Streak Share and Thread Splitter. No message cap is stated on the tracking line.

That makes it the cheapest genuine answer on this page for anyone who wants opens and clicks in Gmail and nothing else. The paid plans exist to sell the CRM around it, under a heading that page states as "Straightforward plans. No surprises. No addons. No required fees." As published on streak.com on 2 September 2026, that page shows Pro at $49 and $59 per user per month either side of a toggle labelled Annually 20% off, Pro+ at $69 and $89, and Enterprise at $129 and $159. The lower figure in each pair is the annual rate. Our page on Streak as a Gmail-native pipeline covers where the CRM half stops being enough.

Mailsuite, formerly Mailtrack

Mailsuite prices the history rather than the volume, which is the most interesting design on this list. Its plan comparison, as published on mailsuite.com on 2 September 2026, shows tracked emails as Unlimited on all three plans including the free one. What moves is the tracking history: the free column reads "Only First open", the middle plan reads "Last 7 days", and the top plan reads "Full tracking history".

Link clicks are capped instead: on that page the free column allows 10 emails with tracked links against unlimited on the top plan, under a feature the page describes as "Know when your recipients click on the links in your emails." The prices on that page were served to our fetch in euros rather than dollars, which is a known behaviour of geolocated pricing pages, so no Mailsuite price is quoted here. Read it from your own connection before budgeting.

Right Inbox

Right Inbox publishes the clearest ladder of the six, on a page headed "Works with Chrome, Safari and Firefox". As published on rightinbox.com on 2 September 2026, that page shows the Limited plan at $0.00 marked "Solo use only", Professional at $9.95 per month monthly or $7.95 per month yearly marked "Per-user pricing", and Team at $19.95 per month monthly or $16.95 per month yearly with "Unlimited team members".

The free plan is genuinely limited: its column shows caps of five per month across the feature set rather than a smaller version of the paid product. Professional shows Unlimited against every row.

Mixmax

Mixmax caps the free tier by message count. Its feature comparison, as published on mixmax.com on 2 September 2026, shows the Free plan allowing "20 tracked emails" against Unlimited on Inbox Copilot, with click tracking capped the same way.

Read the tier names before the prices. The page opens with "Get started from $29/month." and that headline rate buys two different things. On that page Inbox Copilot publishes $29 per user per month billed annually and $34 billed monthly, and it is the tier where tracking goes unlimited. The same page shows Meeting Copilot at $29 and $34 with its open tracking row still reading 20 tracked emails, so paying that price for the wrong copilot buys no more tracking than the free plan does. That page also publishes Engagement Copilot at $49 annually and $65 monthly, and the full Mixmax Suite at $89 annually and $105 monthly. Our page on what Mixmax charges works through the rest of the ladder.

Yesware

Yesware's pricing page opens on its monthly tab, so those are the figures a visitor sees first, under a line stating that "Yesware offers flexible pricing plans, including a Free Forever option". As published on yesware.com on 2 September 2026, that page shows Free at $0 per seat per month, Pro at $19, Premium at $45 and Enterprise at $85 billed monthly; the annual tab shows $0, $15, $35 and $65.

Free carries "Basic Email Open Tracking" and "10 Campaign Recipients/Month"; Pro carries "Unlimited Email Open Tracking" and "20 Campaign Recipients/Month". Those campaign limits are the tell that this is an inbox tool with a sample of outbound attached rather than a sending platform.

One detail on that page is easy to miss and worth more than the prices. Its complete feature list attaches the note "Limited to emails sent less than 24 hours ago." to open tracking, link tracking and the inbox activity feed. A tracking product whose history window can be measured in hours is a notification service, which is a reasonable thing to buy and a poor thing to report on. What the Yesware open notification proves goes further into the product.

HubSpot

That page publishes no price and answers the question in prose instead: "HubSpot’s email tracking is part of Sales Hub, and you can get started with it for free," as published on hubspot.com on 2 September 2026. The same page states that it "notifies you when a prospect opens your email and clicks a link inside" and that it works with Gmail, Google Workspace, Outlook and Office 365.

For a team already on HubSpot this settles the question without a purchase. For a team that is not, the tracking is not a reason to arrive.

What tracking costs the message it measures

Tracking is not free at the deliverability layer, and vendor pages in this category never lead with it.

An open pixel is a remote image, and a message carrying a remote image looks different to a filter than one without. A tracked link is a rewritten link, so the URL a recipient sees points at a redirect host rather than at the destination, and a shared redirect host inherits the reputation of everyone else sending through it. Owning the redirect domain is the mitigation, and the mechanics sit in custom tracking domain.

None of that makes tracking a mistake. It makes it a trade. For a considered one to one email to a named prospect, where the reply matters more than the deliverability margin, it is usually a fair swap. For a first cold message at volume, where the cleanest possible message is the one with no images and no rewritten links, the arithmetic is much less obvious. The full diagnostic order sits in our cold email deliverability guide.

What to do with the data once you have it

• ✓Yes: Diagnose whether a campaign reached inboxes at all, read at campaign level rather than per person
• ✓Yes: Read link clicks as interest in one specific piece of content
• ✓Yes: Notice a document opened repeatedly, which is a real signal about attention
• ~Depends: Compare two subject lines on reply rate, with opens as a secondary read
• ✕No: Treat one open as evidence that a person read the message
• ✕No: Trigger a follow-up email because a pixel fired
• ✕No: Report an open rate to a client as a measure of how many people saw the message

Why the open rate stopped being a number

Every vendor on this page still reports an open rate, and the metric degraded underneath all of them at once. Apple's Mail Privacy Protection loads remote content in the background whether or not a person looks at the message, and Apple's own guide says it prevents senders from seeing whether the message was opened. Corporate security tools fetch every URL in a message before delivery, producing both opens and clicks nobody performed. Gmail lets a recipient turn image loading off entirely.

The direction of the error is what matters. Preloading inflates opens and suppression deflates them, and neither is distributed evenly across your list, so the number moves with your audience mix rather than with your copy. Our cold email open rate benchmarks page covers what the metric now carries across the category, and open rate covers what the pixel counts.

There is a cheap test that settles it for your own stack in an afternoon and needs no vendor cooperation. Send the same tracked message to a set of mailboxes you control across the providers your prospects actually use, then leave every one of them unopened for a day. Whatever the dashboard reports is your floor for false positives. If that floor is high, every open number afterwards carries it.

What we do with an open, which is nothing

Every product here markets tracking as the trigger for a well timed second touch. That is not the motion we run. We send one message per campaign, we do not send thread replies or bump sequences, and a non-responding audience becomes a new campaign with a genuinely different premise rather than a reminder attached to the old one.

Two reasons for that stand independently of any house rule. If a preload produced the open, the follow-up it triggered is aimed at somebody who never saw the first message and arrives referencing something they have no memory of. And reply rate is measurable while open rate increasingly is not, so a workflow keyed to opens is a workflow keyed to the metric that broke.

1. Step 1Name the decision

   Write down the action you would take differently because of a tracking event. If there is none, the free tier is the whole purchase.

2. Step 2Check what you already own

   Sending platforms and CRMs bundle this. Buying it twice is the most common overspend in the category.

3. Step 3Test the false positive floor

   Send to mailboxes you control, leave them closed for a day, and read what the dashboard claims.

4. Step 4Buy the cheapest tier that clears the cap

   The tiers above it sell CRM, sequencing and reporting, which are separate purchases with separate cases.

How to choose, in one pass

If you send from Gmail and want opens and clicks with nothing attached, Streak's free email power tools cover it. If you want unlimited tracked messages and can live with seeing only the first open, Mailsuite's free plan does that and prices its history rather than its volume. If you are a single seller wanting a clear per user price with no CRM around it, Right Inbox publishes the plainest ladder. If your team already pays for HubSpot, the tracking is included and the question is closed.

If you want tracking beside sequencing, read the tier boundaries rather than the headline: Mixmax gates unlimited tracking to one specific copilot at its entry price, and Yesware's campaign recipient limits mean its outbound half is a sample rather than a platform. For sending at volume the whole comparison changes, and cold email platforms is the category to read instead.

The honest summary is that this is a small purchase pretending to be a large one. The signal has degraded on both sides at once, the mechanism is identical across vendors, and the free tiers already cover the uses that survive that degradation.

If the outcome you want is booked meetings rather than a better view of what happened to the last email, see what a campaign would look like for your market.

Every price, plan name and cap above was read from the vendor's own pricing page in a snapshot taken on 2 September 2026, and each figure is attributed to the page it came from rather than to the vendor in general. Mailsuite's page served euro prices to that fetch, so no Mailsuite price appears above. Verify current terms with the vendor before relying on them.
