How to choose an email tracker Chrome extension

28 August 2026 · 2 min read · The Bulk Mail team

Search the Chrome Web Store for email tracking and you get dozens of results that all promise the same thing. They differ in ways the listing pages rarely make obvious. These are the questions that matter.

1. Does it put branding in your emails?

This is the first thing to check and the most common unpleasant surprise. Some extensions add a signature line to every message on the free tier. Send one to a client and they know. Look for a tool that adds nothing visible on any plan.

2. What exactly is limited on the free plan?

A cap on tracked sends per month means the tool stops working when you are busiest. A cap on how far back you can see history means it always works, and you simply lose the older records. The second is much easier to live with.

3. Where does the status show up?

If open status appears next to your threads in the Gmail Sent folder, you will see it as part of your normal day. If it lives in a separate dashboard, you will check it twice and then stop. This single detail decides whether a tracker becomes a habit.

4. What permissions does it request?

An extension that runs inside Gmail necessarily asks for access to the Gmail tab. Read the permission prompt anyway, and be suspicious of anything requesting access to all sites when its job is one site.

5. Can you get the data out?

Sooner or later you will need to show that something was sent and opened — a contract, an invoice, a notice. An exportable, timestamped record turns that from an argument into a document. Most trackers cannot do it.

6. Can you delete your history?

You are creating a record of who read what and when. Check that you can wipe it, and check how long the tool keeps data you have not asked it to keep.

Shortcut: install two candidates, send yourself the same email through each, and look at what arrives. The one that changed your message is the one to remove.
