Best email tracker for Gmail: choose by workflow
The right choice depends on what you need after an open signal: a simple notification, a reminder, or a broader customer workflow.
This is an editorial comparison of published capabilities, not a hands-on performance ranking. Our Gmail extension is available from the Chrome Web Store, while this table keeps the published provider comparison separate from our own product. Check each provider's current terms before installing or paying.
| Provider | Useful starting point | Tradeoff to check |
|---|---|---|
| MailTracker | A small-volume Gmail workflow | The free tier lists 20 tracked emails per month. |
| Mailsuite / Mailtrack | Unlimited basic tracking | Free accounts add a promotional signature. |
| Streak | Tracking alongside Gmail customer workflows | Separate the tracking feature from the wider CRM plan. |
| Mailbutler | More detailed engagement controls | Review plan access and privacy-related data limits. |
| Boomerang | Scheduling and recipient-aware receipts | Review message credits and recipient opt-out behavior. |
MailTracker: start with your sending volume
The provider lists a free plan with 20 tracked messages per month and no added signature. That may suit occasional outreach. If your workflow needs more, check the paid plan's billing interval and features instead of assuming that every capability is free.
Mailsuite: understand the free-tier branding
Mailtrack is part of Mailsuite, not a separate competitor in this table. Its free offering includes unlimited basic tracking, with promotional branding. If a clean outgoing message is important to you, compare the cost of removing the signature before switching.

Streak: consider the broader workflow
Streak publishes a free Gmail tracking offering and also provides a CRM. It is worth evaluating when your real task is organizing contacts and conversations. Check which features belong to the lightweight extension and which require a broader subscription.
Mailbutler: inspect the event details
Mailbutler documents open tracking, self-tracking prevention, and per-recipient controls. Those options may matter when you send to groups. Its documentation also explains that Apple's privacy features can hide location and device details; do not assume the dashboard can recover them.

Boomerang: combine timing and receipts
Boomerang pairs email productivity features with open and link observations. Its receipt workflow includes an opt-out window for recipients. If scheduling and follow-up timing matter more than an activity feed, test whether that workflow fits the way you send.
Test the best email tracker for Gmail for your needs
To find the best email tracker for Gmail for your situation, write down your monthly message volume, whether branding is acceptable, and which event would change your next action. Then test with accounts you control before using the tool for real conversations.
Review requested permissions, retention policies, export options, and cancellation terms. Test blocked images and forwarded messages as well as a normal open. A polished activity panel is useful only if you understand the evidence behind its labels.
Do not compare tools solely by their claimed accuracy. No provider can make an image request prove that someone read and understood your message. A direct reply is still the stronger signal when a decision matters.
Measure the cost of switching
Include more than the monthly subscription in your comparison. A team may need time to review permissions, update internal instructions, and explain changed behavior to colleagues. Check whether useful history can be exported and whether notifications can be tuned to avoid distraction. A limited pilot with a few ordinary conversations is easier to evaluate than enabling every feature at once.
