The Best Free Email Tracker for Gmail - What's Actually Free in 2026
You sent a proposal Tuesday afternoon. It's now Thursday. You've refreshed your inbox eleven times. Did they open it? Did it land in spam? Did the email even reach a real person?
That anxiety is why email trackers exist - but most "free tracker" lists are stuffed with tools that aren't actually free. They're trials, teasers, or free plans so limited they're useless after day one. We've tested the major options and sorted the genuinely free from the bait-and-switch. Here's what we found.
Our Picks (TL;DR)
| Pick | Best For | Verdict |
|---|---|---|
| Snov.io Email Tracker | Truly free - no limits, no catch | Unlimited opens + clicks, no signature |
| Mailtrack | Popular but comes with baggage | Unlimited opens, but adds a promotional footer to every email |
| Streak | Free Gmail CRM with basic tracking | Open tracking inside a CRM. No click tracking on free |
Do Gmail Trackers Still Work in 2026?
Open tracking has gotten noisier every year since Apple launched Mail Privacy Protection in September 2021. MPP generates machine opens - your tracker says "opened" when really Apple's servers pre-fetched the tracking pixel. It also masks IP addresses, so you can't tell where someone opened from. Apple's Link Tracking Protection can strip UTM parameters entirely.
Gmail adds another layer of noise because images route through Google's infrastructure, which makes open signals less precise than people expect.
Does that mean trackers are useless? No. Click tracking still works reliably across all clients. And open tracking is directionally useful - if someone opens your email five times, that's a real signal even with noise. But the smart move is clear: prioritize clicks over opens and replace open-triggered automations with click-based triggers.
The Deliverability Risk Nobody Mentions
Here's something most free tracker lists skip entirely: many free extensions route tracking through shared domains. If that shared domain gets flagged for spam - because another user on the same tracker was blasting cold emails - your deliverability suffers too. The most common ask in tracker discussions on r/sales is a free option with no branded signature, but the question people should be asking is whether the tracker's infrastructure will land their emails in spam.
Before you worry about tracking, look for extensions that use their own tracking infrastructure or let you configure a custom tracking domain. And verify your list first. If 20-30% of your emails bounce, your tracking data is measuring noise on top of noise. Prospeo's email verification handles this at 98% accuracy across 143M+ verified emails, so you're only tracking messages that actually reached real inboxes.
Let's be honest: most teams obsess over open rates when the real problem is that a quarter of their list is dead. Fix the list first. Tracking is step two.
Free Tracker Comparison Table
Most tools below have a genuinely free plan - not a trial - but the limits vary a lot.
| Tool | Opens | Clicks | Free Limit | Signature? |
|---|---|---|---|---|
| Snov.io | Yes | Yes | Unlimited | No |
| Mailtrack | Yes | Paid only | Unlimited | Yes |
| Streak | Yes | No | Unlimited | No |
| Hunter MailTracker | Yes | Yes | 20/month | No |
| Yesware | Yes | Yes | Unlimited | No |
| HubSpot | Yes | No | 200 notifs/mo | No |
| Right Inbox | Yes | Yes | 10 actions/mo | No |
Snov.io is the only Gmail tracker free of caps and branding. Mailtrack gives you unlimited tracking but stamps every email. Everything else has meaningful limits. Here's what each tool actually looks like in practice.
You're tracking opens on emails that never reached a real inbox. If 20-30% of your list bounces, your tracking data is noise. Prospeo verifies emails at 98% accuracy across 143M+ addresses - so every open and click you track is a real signal from a real person.

Top Free Email Trackers for Gmail
Snov.io Email Tracker
Use this if: You want a no-strings-attached free tracker that just works. Skip this if: You need mobile tracking or deep CRM integration.
Snov.io's email tracker is the rare Chrome extension that's genuinely, completely free. No paid tiers for the tracker itself. No signature appended to your emails. You install it, and it tracks opens and clicks with real-time desktop notifications - unlimited.
The numbers back this up: a 4.9 Chrome Web Store rating, 100K+ users, and 8K+ five-star reviews. Snov.io also publishes transparent source code and explicitly positions the extension as not using your data - a trust signal many trackers don't offer. We ran it for three weeks on a 200-email outbound sequence and never hit a limit or saw a branded footer slip through.
The limitation is scope. It's a tracker, not a platform. No CRM features, no templates. But if all you need is "did they open it and did they click," Snov.io is the obvious answer.
Mailtrack (Mailsuite)
Mailsuite, formerly Mailtrack, is one of the most-installed free Gmail tracking extensions available. The free plan gives you unlimited open tracking. The catch is hard to ignore: every email you send gets a promotional "Sent with Mailtrack" footer. For personal use, that's fine. For sales outreach, it screams "I'm tracking you."
Click tracking requires a paid plan (Pro at $1.99/mo or Advanced at $4.99/mo). Capterra rates it 4.5/5 from 163+ reviews, and G2 gives it 4.6/5 from 106+ reviews. Solid product, but the footer is a dealbreaker for anyone doing B2B outreach. Skip this one if you're sending anything client-facing.
Streak
Use this if: You want a free CRM with basic tracking built in. Skip this if: You only want a lightweight tracker.
Streak is a different animal entirely. It's a CRM that lives inside Gmail, and email tracking is included in the free plan. The integration is tight - you see tracking data right in your inbox without switching tabs or apps.
The tradeoff: free Streak only tracks opens. No click tracking. And while Capterra gives it 4.5/5 from 479 reviews with strong praise for the Gmail integration, reviews also frequently mention bugs and reliability issues. Paid plans start at $49/user/month, which is steep if you only want tracking. We found it most useful for freelancers or solo founders who want a lightweight pipeline view alongside their inbox - not for teams running serious outbound.
Hunter MailTracker
Hunter's MailTracker is clean and lightweight: open and click tracking plus real-time notifications and follow-up reminders. The problem is the free plan caps you at 20 tracked emails per month. That's roughly one email per business day. For someone sending occasional proposals, it works. For anyone doing regular outbound, you'll hit the wall by week two. Paid plans start around $20-$30/month. With 100,000+ downloads, it's well-established - just too limited on free for daily use.

Yesware
Yesware offers a Free Forever plan with unlimited tracking, and its paid tiers are clearly listed (Pro at $15/mo, Premium at $35/mo, Enterprise at $65/mo). If you want tracking plus sales templates and reporting, it's worth a look. The free tier is genuinely usable, though the interface feels heavier than a standalone tracker.
If you're building a full outbound stack, these SDR tools can help round it out.
HubSpot Sales Hub
HubSpot's free tier includes open tracking, but it's capped at 200 email notifications per month - roughly 6-7 tracked emails per day. No click tracking on free. Paid plans start at $15/seat/month, and Professional is commonly priced at $100/seat/month plus a $1,500 onboarding fee. Best if you're already deep in the HubSpot ecosystem. Otherwise, overkill for tracking alone.
If you're evaluating CRMs beyond HubSpot, start with these examples of a CRM.
Right Inbox
Free plan gives you 10 send-later emails, 10 reminders, and 10 private notes per month. That's barely functional for testing. Paid plans run about $7.95-$14.95/month billed annually. 250,000+ users, but the free tier is a demo, not a product.
If you mainly need reminders and follow-ups, consider dedicated follow up email software.
Tools We Excluded (and Why)
Not every "free" tracker is actually free. We cut three popular names:
- GMass - Offers a 7-day free trial limited to 50 emails/day. After that, paid plans start at $25/month. It's a trial, not a free plan.
- Salesflare - A paid CRM with plans starting at $29/month. No free tracking tier.
- Mailbutler - Has an Essential (free) plan, but it's primarily designed to push upgrades to paid tiers. The free functionality is too thin to recommend.
If you're looking for genuinely $0 options across your stack, these free lead generation tools are a better starting point.
Verify Before You Track
Look, here's the thing most email tracker articles never mention: tracking opens on unverified addresses means measuring noise. If 20-30% of your list bounces, your open rates are meaningless - you're calculating percentages against a denominator full of dead addresses. We've seen teams celebrate a "45% open rate" that was really 45% of the 70% that actually delivered. The real number was closer to 31%.
Prospeo's 5-step verification process includes catch-all handling, spam-trap removal, and honeypot filtering. Data refreshes every 7 days - the industry average is 6 weeks, so most databases are serving stale contacts while Prospeo's stay current.
If you want to go deeper on bounces and what they do to your domain, read our guide to email bounce rate and the full email deliverability guide.
The free tier gives you 75 email verifications plus 100 Chrome extension credits per month. Paid plans run about $0.01 per email - cheaper than the cost of a single bounced email hitting your domain reputation. The workflow is simple: upload a CSV, verify in bulk, export clean contacts, push to your sequencer. Do this before you install any tracker.
Free trackers tell you who opened. Prospeo tells you who to email in the first place. Search 300M+ profiles with 30+ filters - buyer intent, technographics, job changes - and export verified contacts at $0.01 per email. No contracts, no sales calls.
Stop tracking dead leads. Start reaching the right ones.
Privacy and Compliance
Email tracking isn't just a product decision - it's increasingly a legal one, especially if you're emailing EU or UK recipients.
The EDPB's Guidelines 2/2023, adopted October 7, 2024, clarify that pixel and URL-based tracking falls under ePrivacy Article 5(3) on a technology-neutral basis - tracking pixels are treated like cookies. The UK's ICO confirmed the same under PECR: prior consent required unless tracking is "strictly necessary." France's CNIL went further with draft recommendations in June 2025, proposing separate consent for marketing emails versus tracking pixels.
In the US, there's no single federal statute covering email tracking, but plaintiffs have used ECPA (Wiretap Act) theories and California's CIPA 631(a) in email-tracking lawsuits. The legal landscape is shifting fast.
Your compliance checklist:
- EU/UK recipients: Get consent before tracking. Tracking pixels = cookies under EDPB guidance.
- US recipients: Lower legal risk, but rising. Disclose tracking in your privacy policy.
- Everywhere: Prefer click tracking over open tracking - clicks require active engagement and face less regulatory scrutiny.
- When in doubt: Use verified email lists and click-based triggers instead of open-based automations.
FAQ
Which free Gmail tracker has no signature?
Snov.io Email Tracker is completely free with no branded signature and no caps. Hunter MailTracker and Streak also avoid signatures on their free plans, though both have other limitations - 20 emails per month and opens-only tracking, respectively.
Can email trackers detect opens on Apple Mail?
Not reliably. Apple Mail Privacy Protection generates machine opens and masks IP addresses, making open tracking inaccurate for Apple Mail recipients. Click tracking remains reliable across all email clients, which is why most experts recommend prioritizing link clicks over pixel-based open signals.
Is GMass actually free?
No. GMass offers a 7-day free trial limited to 50 emails per day. After the trial, paid plans start at $25/month. It doesn't qualify as a free email tracker - it's a time-limited demo.
Can recipients see that I'm tracking their email?
Most trackers use an invisible 1x1 pixel, so recipients won't see anything in the email body. Tech-savvy recipients can inspect the email source and spot the tracking pixel, though. Mailtrack's free plan is the exception - it appends a visible promotional footer, making the tracking obvious. For stealth, use Snov.io or Hunter MailTracker.
Should I verify emails before tracking them?
Yes. Tracking unverified lists means measuring noise. If 20-30% of addresses bounce, your open-rate data is meaningless. Prospeo's free tier includes 75 email verifications per month at 98% accuracy, which is enough to clean a small outbound list before you start tracking.
