Best Email Tracking Software for 2026: 11 Options Compared by Use Case

Yesware has tracked sales email since 2010, longer than any other tool here, and that maturity shows in the details: the free plan covers basic open and attachment tracking, a meeting scheduler and 10 campaign recipients a month, so a solo rep can start tracking without paying anything. Pro costs $19 a seat a month, or $15 billed annually, and removes the limits with unlimited open, link and attachment tracking.

Premium costs $45 a seat a month and adds team reporting, shared templates and unlimited campaigns, while Enterprise at $85 adds the Salesforce sync that larger teams need. The trade-off is scope: Yesware lives in Gmail and Outlook only, and the free tier is deliberately thin. Buy it when you want the proven default for a sales team that works from the inbox.

Mailsuite, formerly Mailtrack, is the simplest tracker in this list: a Gmail and Outlook extension that puts double check-marks beside an email the moment it is opened, with a real-time notification to match. The free plan tracks unlimited opens, which is enough for a freelancer checking whether a proposal was read, though every free email carries a visible Mailsuite signature.

Paid plans start with Mailtrack at €6.99 a user a month, which removes the signature and adds link tracking and a week of history; the Mailsuite plan at €19.99 adds full history and campaigns. There is no CRM and no sequencing, so this is a tracking tool and nothing else. Pick Mailsuite when the only question you need answered is whether an email was opened.

HubSpot is the only tool here where tracking comes with a real CRM at no cost: the free tools include open and click tracking in Gmail and Outlook, contact management, deal pipelines and meeting scheduling for up to two users. Every open is logged against the contact and deal automatically, so a follow-up call starts with the full history instead of a guess about whether the email landed.

Sales Hub Starter costs $20 a seat a month at list, with a limited-time $7 rate for new customers on annual billing, and adds more pipelines, workflows and calling minutes. Professional jumps to $90 a seat a month plus a $1,500 onboarding fee, which is where sequences and forecasting live. Choose HubSpot when tracking should feed a CRM, not sit in a browser extension.

Streak lives entirely inside Gmail as a browser extension, and its free plan is the most useful free tier here for a Gmail user: email and link tracking, snippets, 50 mail-merge sends a day and thread tools, all at no cost. Tracked opens feed straight into deal records, so the pipeline and the inbox stay in sync without anyone copying data between apps.

The catch is the price of the CRM itself: the old free CRM tier is gone, so pipelines start on Pro at $49 a user a month billed annually, or $59 month to month, and automations need Pro+ at $69. There is no Outlook support at any price. Buy Streak when your whole team lives in Gmail and wants the pipeline where the email already is.

Mixmax turns Gmail into a sales engagement tool, and its free plan is generous: email tracking, scheduling, templates, polls and surveys, with no card required. The paid plans are now sold as Copilots — Inbox Copilot at $29 a user a month billed annually, or $34 month to month — and add mail merge, shared calendars and shared templates for small teams.

Engagement Copilot at $49 billed annually adds sequences and rules-based automation, while the full Suite reaches $89. Interactive touches like polls and calendar embeds are the draw, and they sit inside the email itself. Pick Mixmax when outreach should feel engaging rather than templated, and check the Copilot pricing carefully before you budget.

Mailbutler is the only tracker in this list that works the same way in Apple Mail as it does in Gmail and Outlook, which makes it the default for mixed-device teams. The free Starter plan includes unlimited tracked emails and signatures, with a visible watermark, while the paid Starter at $5 a user a month, or $4 billed annually, removes it.

The Smart plan at $14 a user a month, or $11 billed annually, is the one most buyers want: per-recipient tracking on group sends, plus device and location details for each open. Business adds a custom tracking subdomain and CRM sync. Choose Mailbutler when your team is split across mail clients and needs identical tracking everywhere.

Right Inbox is the minimalist option: a Gmail extension that adds open tracking, send-later scheduling, reminders and templates to the compose window, with nothing to configure. The free plan covers 5 tracked emails a month, which is enough to test it, and Professional at $9.95 a month, or $7.95 billed annually, removes the cap entirely.

The Team plan at $19.95 a month, or $16.95 billed annually, covers unlimited members, which keeps a small team cheap. The limits are clear: Gmail only, no CRM, and mail merge sits on Professional. One warning from reviewers: Trustpilot carries reports of charges continuing after cancellation, so check your billing after any trial.

GMass turns Gmail into a mail-merge and campaign tool, and tracking is built into every send: opens and clicks, custom tracking domains and campaign reports come with the Standard plan. Prices rose on January 1, 2026, so Standard now costs $29.95 a month, or $20 a month billed annually at $249 a year, and the old $25 rate you will see in older roundups is stale.

Premium at $39.95 a month adds follow-up sequences, API access and A/B testing, while Professional at $59.95 adds inbox rotation for larger senders. The free plan is gone — new accounts get a 7-day trial capped at 50 emails a day — and Gmail's own sending limits still apply. Pick GMass when campaigns run from Gmail and nowhere else.

Apollo is the only tool here that finds the people to email as well as tracking them: a database of 275 million contacts with 65 search filters, sequences, a dialer and an AI assistant in one seat. The free plan includes 900 credits a year, and Basic at $65 a user a month, or $49 billed annually, adds 30,000 credits a year, unlimited sequences and email warm-up.

Credits are the catch: one credit reveals an email, eight reveal a phone number, and unused credits expire at the end of each billing cycle. Data accuracy is also the top complaint in G2 reviews, so verify before you trust a list. Choose Apollo when one seat should cover finding, emailing and tracking, not just the tracking.

Lemlist prices by sending volume, not by seat, which makes its Email plan the bargain of this list for teams: $69 a month, or $55 billed annually, covers unlimited users and senders and 50,000 emails a month. Warm-up is included on every plan, and dynamic images and AI personalization sit in the same builder as the sequences.

The trade-off is credits: the Email plan includes none, so finding and verifying addresses costs extra at $10 per 1,000 credits, and Multichannel Expert jumps to $109 a user a month for LinkedIn, calls and SMS. Pick Lemlist when the whole team sends email and one flat price beats five per-seat bills.

Staffbase Email, formerly Bananatag, is the only tool in this list built for internal communications: it tracks opens, clicks and engagement on employee email, then breaks the numbers down by department, location and role. Pulse surveys run inside the message, and distribution lists keep company-wide sends manageable, all with Outlook integration.

There is no price list and no free plan: Staffbase sells by tailored quote only, with annual billing and modular packages, and deployments typically take three to four months. That makes it the most expensive and slowest option here by a wide margin. Buy it only when proving employees read company email is the job itself.
