8 Best Email Tracking Tools in 2026
An email tracking tool records what happens after you hit send, whether the recipient opens your email, what links they clicked, how many times they came back to it and from which device. For sales teams, that behavioral data determines follow-up timing. For marketing teams, it identifies which subject lines drive actual opens.
With over 376.4 billion emails expected to be sent daily in 2025, tracking recipient behavior has become necessary. In this guide, we’ll cover the 8 best email tracking tools in 2026 as per their features, pricing, deliverability impact, and usability.

What is an Email Tracking Tool?
Email trackers insert a hidden picture within the email. That image displays when the recipient opens the email, notifying the sender that the email has been opened and when.
Most tools capture more than just open events. Link clicks, re-opens, device type, and location are all recorded. Sales reps use that data to follow up when a prospect is actively engaged, not days later without any signal to act on. Marketers use it to figure out which subject lines are actually driving opens. Recruiters use it to see whether a candidate has even looked at their outreach.
One thing worth knowing: Apple Mail Privacy Protection (MPP) pre-loads emails in the background. That means open events can trigger even when the recipient never actually opened your email.

How to Choose the Right Email Tracking Tool?
You must check the following criteria to choose the best email tracking tool for your business.
1. Identify Your Primary Use Case
Individual Gmail users needing basic open tracking: Mailtrack or MailTracker. Sales team managing deals: HubSpot or Streak. Cold outreach at scale: SalesHandy. Team performance visibility: EmailAnalytics.
2. Check Deliverability Impact
Some trackers embed pixels that cause emails to land in spam. EmailAnalytics has zero deliverability impact (API-based). Others vary. Test with your own domain before deploying to your full team.
3. Consider CRM Integration
Check whether the tracker logs data automatically to your CRM or requires manual export. Automatic logging is the difference between a tool your team uses daily and one they abandon within a month.
4. Evaluate The Pricing Model Carefully
The per seat cost can begin to increase as the team grows. For instance, $29.00 per user, 10 users is $290.00 per month, without additional fees. Therefore, do the necessary tool comparisons. Some charge by user, others charge by inbox. So, depending on the size of the team, it may be cheaper to pay by inbox.
5. Account for Apple Mail Privacy Protection
Open rates have been inflated since MPP launched - Apple pre-fetches pixels whether or not the recipient reads the email. If your audience skews toward Apple Mail users, open data alone is unreliable. Weight click-through and reply signals more heavily when evaluating which tools give you actionable data.
Choose the Tool That Matches Your Workflow
Attaching email tracking is only reliable if your email list is verified and contains valid email addresses. Since sending emails to unverified recipients increases bounce rates and lowers open rates. An email verifier helps eliminate these issues before you begin any outbound campaigns.
To get a bounce rate less than 3% and a 99.73% accurate contact verification results, use Clearout's email verifier. This will help tracked emails to go to real inboxes and engagement data will be accurate enough to act on.

FAQs
1. Which is the best free email tracking tool for Gmail?
Mailsuite is the most popular free Gmail email tracker. It adds double-tick read receipts to your sent emails. The free plan is fully functional but adds a "Sent with Mailsuite" signature to every email.
2. Does email tracking affect email deliverability?
It can. Tools that insert tracking pixels carry some deliverability risk, especially if their domain is shared across many senders and gets flagged. EmailAnalytics avoids this entirely by using API-based tracking with no pixel insertion. For pixel-based trackers, verifying your list with Clearout before sending keeps bounce rates under 3% and preserves inbox placement.
3. Can email tracking tools work with Outlook?
Yes. HubSpot Sales Hub, Yesware, SalesHandy, and EmailAnalytics all support Outlook. Gmail-only tools like Mailtrack, MailTracker, Streak, and Mixmax don't currently offer native Outlook support.
4. Is email tracking legal in the US?
Email tracking is generally legal in the US. There's no federal law that explicitly prohibits tracking pixels for open detection. You should still comply with CAN-SPAM for marketing emails. In the EU, GDPR applies more strictly. So, always check the rules relevant to your audience's location.
5. What's the difference between an email tracker and an email verifier?
An email verifier checks if an address is valid before you send, helping reduce bounces and protect your sender reputation. An email tracker shows what happens after delivery, including opens and clicks.
