10 Best Gmail Add-ons
1. MailTracker
MailTracker helps you see what happens after you send an email so you can take action at the right moment.

The add-on is trusted by 100,000+ users and has a 4.7/5 rating on the Chrome Web Store, which shows how widely it’s used for daily email work.
Once you install MailTracker, it runs in the background and adds tracking signals next to your sent emails.
When someone opens your email in Gmail, comes back to it, or clicks a link, you see that activity immediately. These signals help you decide when to follow up, when to wait, and when to move on.
You can use MailTracker when the timing of your emails matters. When you see an open or re-open, you know your message is back on someone’s screen.
When an email stays unopened, you know it’s time to stop chasing and focus on higher-priority conversations. That’s how MailTracker turns Gmail into a decision-making tool, not just an inbox.
Features
MailTracker adds practical tracking signals directly to Gmail:
- See when an email is opened so you know it reached the inbox
