The best free email tracker for Gmail
“Free” email trackers vary more than you’d expect — some add a signature, some cap you at 20 emails a month. Here’s what actually matters, and how the leading options compare.
Six things that separate a good free tracker from a frustrating one
No signature or branding
Many “free” trackers append a “Sent with…” line to every email. On professional messages, that alone is a reason to switch.
Real free limits
Check whether “free” means unlimited tracking or a small monthly cap. A 20-email limit runs out fast.
Per-recipient tracking
When you email several people, can it tell you which one opened it — or just that someone did? The former is far more useful.
Link-click tracking
Opens tell you the email was seen; link clicks tell you what the recipient cared about. Some tools gate this behind paid plans.
Real-time notifications
A read receipt is most useful the moment it happens, so you can follow up while you're still top of mind.
Privacy you can trust
Prefer tools that are opt-in, don't sell your data, and filter out your own opens and automated scanner prefetches.
Leading free email trackers for Gmail
Each tool leans a different way. Match the pick to how you actually send email.
Driploop
Best for signature-free, per-recipient tracking
Free Gmail read receipts with per-recipient open tracking, link clicks, and follow-up reminders — and no signature added to your emails.
Mailtrack / Mailsuite
Best known name
The most recognizable tracker (Mailtrack rebranded to Mailsuite). Its free plan is widely documented to add a “Sent with” signature, with link tracking and reminders on paid tiers.
Streak
Best if you also want a CRM
A Gmail-based CRM that also includes email tracking. A good fit if you want pipelines and tracking together rather than a standalone tracker.
Boomerang
Best for scheduling & reminders
Best known for send-later scheduling and inbox reminders, with read-receipt tracking available. Check current free-plan limits on their site.
Positioning is high-level and current as of July 2026; free-plan limits change often, so confirm details on each provider’s site. Product names are trademarks of their respective owners and are not affiliated with Driploop.

Frequently asked questions
What is the best free email tracker for Gmail?
The best free tracker is the one that tells you what you need without adding a signature or a low monthly cap. If you send to groups, prioritize per-recipient tracking. Driploop covers those bases for free; Mailtrack/Mailsuite, Streak, and Boomerang are other well-known options with different trade-offs.
Are free email trackers really free?
Some are genuinely free; others cap you at a small number of tracked emails per month or add a branded signature until you upgrade. Always check the free plan's limits and whether it modifies your outgoing email.
Do free email trackers add a signature?
Several do — a “Sent with…” line is a common way free plans promote the product. Driploop does not add any signature or branding to your emails.
Can a free tracker show who opened a group email?
Per-recipient tracking isn't universal on free plans. Driploop reports which individual recipient opened a shared email and when, so your follow-ups can be targeted.
How accurate is free email tracking?
All pixel-based tracking has limits: privacy features like Apple Mail Privacy Protection and image proxies can pre-load the tracking pixel. Good tools filter your own opens and scanner prefetches so the data you see is more trustworthy.
