Best email tracker for Gmail
The best Gmail trackers share the same basics: accurate read receipts, real-time alerts, and a free tier that does not cap you after ten emails. Here is how the top options stack up.
Top picks for Gmail in 2026
Mail Track for Gmail
Unlimited free tracking, double green read receipts, real-time notifications, visible or invisible tracker, GDPR compliant. Best overall for most Gmail users.
Mailtrack (competitor)
Popular Chrome extension with read receipts. Free tier is limited; premium unlocks full history and reminders.
Mailsuite
Campaign-style tracking with sequences. Strong for bulk outreach; heavier setup than a lightweight Gmail add-on.
What the best trackers have in common
Whether you sell, recruit, or follow up on proposals, these are the non-negotiables.
Native Gmail experience
The best tools live inside Gmail — not a separate dashboard you check once a week. Read status should appear on sent messages where you already work.
Unlimited free tracking
Avoid tools that advertise free but stop counting after a handful of opens. Unlimited tracking on a free plan keeps outreach scalable.
Mobile + desktop parity
Half of opens happen on phones. Top trackers work in the Gmail app on iOS and Android, with push alerts on both.
Our pick for most Gmail users
If you send one-to-one email from Gmail and want unlimited tracking without campaign overhead, Mail Track is the simplest path to accurate read receipts.
- Unlimited free tracking — no monthly open cap
- Native Gmail UI with mobile push alerts
- GDPR compliant; we never read message content
