10 Best Email Trackers for Gmail in 2026

Gmail has no built-in read receipt, no click data, no signal beyond a reply. That's the gap the best email tracker for Gmail options below fill — from free Chrome extensions that just add a checkmark, to full sales platforms with sequences and CRM sync. Here's how the 10 best compare in 2026.

Quick comparison: the best email tracker for Gmail options

1. Mailbutler

Mailbutler works directly in Gmail as an email tracker for Gmail that goes well beyond a basic open notification: per-recipient tracking, real-time alerts, and location & device data on every open. Tracking data also feeds smart follow-up recommendations with one-click AI-drafted replies, plus IP blacklisting, a custom tracking subdomain, and HubSpot/Salesforce sync — alongside mail merge, shared inbox collaboration, signature marketing, and more features for a productive inbox.

Use it if: you want tracking depth (location, device, per-recipient, CRM sync) that most Gmail-only extensions don't offer. Skip it if: you need full CRM-style pipeline management, not just email productivity.

2. Mailtrack

Mailtrack is a simple Gmail extension: a double-checkmark for opens. It also flags false opens and re-opens, but doesn't touch device, location, or per-recipient detail the way Mailbutler does.

Use it if: you want a bare-bones, checkmark-style tracker. Skip it if: you need tracking detail beyond opens.

3. Streak

Streak puts a full CRM inside Gmail — pipelines, deal stages, and tracking in one tab. Pro starts at $49/user/month, a real jump over tracking-only tools.

Use it if: you want a CRM and tracking together, on a small team. Skip it if: you only want tracking — you'd pay CRM pricing for a feature you won't use.

4. HubSpot Sales

HubSpot Sales tracking logs opens and clicks to the HubSpot CRM contact record, free at entry level. Broader Sales Hub features scale from ~$20/user/month.

Use it if: you're already on HubSpot CRM. Skip it if: you don't use HubSpot and don't want to adopt a CRM just for tracking.

5. Yesware

Yesware offers inbox-native tracking and templates from $15/user/month, with a limited free tier. The entry price looks simple, but tracking stays basic — opens and clicks, without the per-recipient, location, or device detail Mailbutler includes. Yesware's CRM sync and campaigns are gated behind pricier tiers too: Salesforce sync needs the $65–85/month Enterprise plan, multi-step campaigns need the $35/month Premium plan — both well above Mailbutler's range (from ~$4/user/month), where tracking depth, follow-up automation, and CRM sync don't require jumping to enterprise pricing.

Use it if: you're a solo rep and specifically want Yesware's template library. Skip it if: you want tracking depth or CRM sync without Yesware's pricier tiers — Mailbutler covers both without the same jump in price.

6. Mixmax

Mixmax layers sequences and scheduling onto tracking, for outbound teams. Its free tier was cut to 20 tracked emails/month in 2025 — now more a trial than a working plan. Paid plans start around $29/user/month.

Use it if: you want Gmail-native sequence automation, not just tracking. Skip it if: you only want tracking — the free tier isn't usable long-term.

7. Boomerang

Boomerang is scheduling-first, tracking is manual per email. Paid plans start around $5/month.

Use it if: scheduling is the priority and tracking is a bonus. Skip it if: you want tracking on by default, not a manual toggle.

8. Right Inbox

Right Inbox covers tracking, scheduling, and templates, but the free plan caps at just 5 tracked emails/month — after that, you're paying ~$10/month for tracking that still stops at opens and clicks, without per-recipient, location, or device detail. Mailbutler's free plan tracks unlimited emails and its paid tiers start lower (~$4/user/month) while including that deeper tracking data plus CRM sync.

Use it if: you specifically want Right Inbox's recurring-email or template features alongside basic tracking. Skip it if: you want meaningful free tracking volume or tracking depth — Mailbutler's free plan is unlimited and its paid tiers go further for less.

9. SalesHandy

SalesHandy grew from tracking into a full cold-outreach platform with sequences, mailbox rotation, and verification, from ~$25/month.

Use it if: you're running structured cold outreach and need deliverability tooling alongside tracking. Skip it if: you just want to track relationship emails — this is more platform than you need.

10. Mailsuite

Mailsuite offers free Gmail tracking with a branded signature, paid plans (~$10/user/month) to remove it and add mail merge. It stops at open/click tracking — no per-recipient breakdown, no location or device detail, no CRM sync. Mailbutler covers all of that from a lower starting price (~$4/user/month), on top of unlimited tracking on its own free plan.

Use it if: you don't need tracking depth. Skip it if: you want per-recipient, location/device detail, or CRM sync — Mailsuite doesn't offer any of it, and Mailbutler does for less.

The bottom line: which email tracker for Gmail should you pick?

Most tools here stop at open/click tracking. If you want a real email tracker for Gmail with tracking depth — per-recipient detail, location and device data, CRM sync — Mailbutler covers more ground in Gmail than any other tool on this list, including on the free plan, which tracks unlimited emails, and it also happens to work in Outlook and Apple Mail if you need that later.
