A straight answer

Which email tracker tells you which recipient opened?

Two Gmail trackers can name which recipient of a group email opened it: Onmindo, and Mailtrack, sold today as Mailsuite, on one of its tiers. Here is what each charges for that, what Gmail permission it asks for, and what the answer is worth once you have it.

Two do, and here is what each costs

Two trackers put a name on the recipient who opened a group email. The rest, MailTracker included, tell you that somebody on the message did.

Tool Price for naming who opened Permission it asks for
Onmindo Free today. Pro is $9 a month, or $84 a year The full Gmail permission, asked only when you switch this on. Send-only by default
Mailtrack (Mailsuite) $19.99 USD per user a month, on the Mailsuite tier only. Absent from Free and from the $6.99 tier "Read, compose, send, and permanently delete all your email from Gmail," asked of every user, Free tier included
MailTracker Does not offer it. Its pricing page says: "MailTracker doesn't identify specific recipients," by design None. Its pricing page says it needs no permission to read or manage Gmail

Picking between them is a permission question as much as a price one. Onmindo's price is the lower of the two, and the full Gmail permission is asked only of the sender who turns naming on. Mailtrack asks every one of its users for that same permission, on every tier including Free, whether they ever use naming or not. MailTracker asks for nothing, and, by its own account, does not name a reader either.

Why the rest say somebody

One email addressed to five people is one thing arriving in five places, and nothing about it tells the five apart afterward.

Naming a reader needs a copy of the message for each one, sent separately under the same To line you typed. Send one message to a group instead, which is what most trackers do, and the honest report is that somebody on it opened it, not which one.

What the name is worth, and what it is not

An open names the mail client that drew the message, Gmail, Apple Mail, Outlook, a browser, or the operating system under it, and the time. It does not name a place, and it does not mean the person read the words.

  • Gmail touches every message as it lands. Onmindo records that as delivered, never as an open.
  • A Gmail reader shows no city and no device next to their open. Gmail loads images through its own servers, so there is nothing true to put there.
  • The same Gmail account opening again, or on a second device, leaves nothing extra for a name on an open to show you.

A name is the strongest thing an open gives you. It is still evidence that a message was read, not proof of it.

Where the answer shows up

Naming the reader is not a separate report. It sits in the same three places Onmindo already shows an open.

  • On the Gmail row itself, as a count, without opening anything.
  • In the hover card on that row, which names each reader, the time and the client.
  • In the dashboard, one row per copy, which keeps working with the extension uninstalled.

All three listen to a live stream from the server, so an open lands while you are looking at the page.

Questions

Naming who opened, answered

The pricing page has the full numbers, and [email protected] answers anything not here.

Can any tracker name who opened a group email?

Two do. Onmindo names the reader for free today, with naming carried into Pro at $9 a month or $84 a year, and Mailtrack, now sold as Mailsuite, names the reader only on its $19.99 a month tier. Both prices were read off the vendor's own pricing page on 8 September 2026.

Why do most trackers only say somebody opened?

An email addressed to five people is one thing arriving in five places, and nothing about it tells the five apart afterward. Naming a reader needs a copy of the message for each one, sent separately, and most trackers send the group message as one.

What does Onmindo need to name the reader?

The full Gmail permission, the one Google's own screen describes as reading, composing, sending and permanently deleting mail. Onmindo asks for it only from the sender who switches naming on, not from every account by default. A message sent without it goes out on the ordinary send-only permission, and its honest answer is the shared one: somebody on it opened it.

What can no tracker tell you?

That the person read the words, rather than that a mail client drew the message for them. A Gmail reader's location, because Gmail draws the message's images itself rather than the reader's device fetching them. And whether the same Gmail account opened the message again on a second device, which leaves no separate record for any tracker to show.
