Which email tracker extension for Gmail is best?

There is no independent ranking we can point to, and HawkOpen will not call itself the best. Compare what matters to you: whether opens from Apple Mail, Gmail’s proxy and scanners are kept apart from people, which mailboxes and browsers are supported, what the free plan includes, and whether recipients are told about tracking.

Checked:

What HawkOpen offers: an extension for Chrome (also meant for Edge, Brave and Opera) and for Firefox, working in Gmail, Outlook on the web and Yahoo Mail, plus a dashboard for any connected mailbox. Every open and click gets a category and a rule code. The free plan has no limit on tracked opens, tracks links in 10 emails a month, keeps 7 days of history and adds a short HawkOpen signature.

What to weigh honestly: HawkOpen is a new and small product without public reviews, while older trackers have many more users and reviews. HawkOpen tracks only recipients whose consent is recorded for your company, and every tracked email carries a visible notice for the recipient. And any Gmail extension depends on Gmail’s page layout, which Google can change.

Where rules that require consent apply, tracking may start only after that consent has been obtained. The link in the message lets the recipient withdraw consent later.

  • How do I track email opens in Outlook?

    In Outlook on the web, install the HawkOpen extension for Chrome or Firefox; if you use the Outlook desktop app, connect your Microsoft mailbox to HawkOpen and send from the HawkOpen dashboard; there is no Outlook add-in. Opens are tracked only after your company’s owner or an administrator switches tracking on, and only for recipients whose consent to open tracking is recorded.

  • How can I get a notification when someone opens my email?

    HawkOpen does not send a notification for each single open. On the Pro and Business plans you set alert rules about opens, such as several opens within 30 minutes or a return to the message after 7 days; when one fires, the browser extension shows a notification, and on Business it can also come by email. Replies notify you on Pro and Business too. This works for emails sent from Outlook on the web, Gmail, Yahoo Mail or the dashboard; machine opens never fire an alert.

  • Does open tracking work when the recipient reads on a phone?

    Yes, when the phone’s mail app loads images. iPhone Mail with Mail Privacy Protection loads them in advance through Apple’s servers, which HawkOpen marks as a privacy proxy, and the Gmail app loads them through Google’s proxy. Opens from other mail apps on a mobile network are classified at most as possible human activity.

  • Is there a HawkOpen app for Android or iPhone?

    No. HawkOpen has no app for Android or iPhone. You send tracked emails from a computer, with the extension for Chrome or Firefox or from the web dashboard, and you see the results in the dashboard.

  • Can I track emails sent from Apple Mail, Thunderbird or another desktop mail app?

    Not from inside those programs: HawkOpen has no add-on for Apple Mail, Thunderbird or other desktop mail apps. Connect the same mailbox to HawkOpen and write tracked emails in the HawkOpen dashboard; they go out from your address.

  • Is there a free email tracker for Outlook?

    Yes, HawkOpen’s Free plan works with Outlook: open tracking has no limit, links are tracked in 10 emails a month, and you get 1 mailbox and 7 days of history. In Outlook on the web you use the browser extension; with the Outlook desktop app you send from the HawkOpen dashboard.

  • How do I connect Gmail or a Google Workspace account to HawkOpen?

    Choose Sign in with Google when you add a mailbox in HawkOpen and allow access. This works for personal Gmail and for Google Workspace accounts; HawkOpen then sends your tracked emails through Gmail from your own address.

  • How do I connect Outlook, Microsoft 365 or Outlook.com to HawkOpen?

    Choose Sign in with Microsoft when you add a mailbox in HawkOpen and allow access. This works for Microsoft 365 work accounts and for Outlook.com and Hotmail addresses; HawkOpen then sends your tracked emails through Microsoft from your own address.

  • Is there an email tracker for Yahoo Mail?

    Yes. The HawkOpen extension for Chrome and Firefox works in Yahoo Mail in the browser, and you can also connect your Yahoo mailbox with IMAP and SMTP and send tracked emails from the HawkOpen dashboard.

  • How do I connect a mailbox with IMAP and SMTP, and do I need an app password?

    When you add a mailbox, choose IMAP/SMTP and enter the server names, ports and password from your mail provider; HawkOpen suggests port 587 for SMTP and 993 for IMAP. Whether you need an app password depends on your provider: many require one when two-step sign-in is on.

  • Can I connect iCloud, GMX, web.de, Zoho, Proton or Fastmail mailboxes?

    Most of them, through IMAP and SMTP: iCloud, GMX, web.de, Zoho and Fastmail offer it, usually after you turn IMAP on in their settings and create an app password. Proton Mail cannot be connected, because it offers IMAP only through its Bridge app on your own computer, which HawkOpen’s servers cannot reach.

  • Does HawkOpen work with every email provider?

    On your side, HawkOpen works with Gmail and Microsoft through their sign-in and with any provider that offers IMAP and SMTP on a public server. On the recipient’s side it works with any mail app that loads images; when images are blocked, clicks and replies are still recorded.

  • How do I disconnect a mailbox and remove HawkOpen’s access?

    Remove the mailbox in HawkOpen’s mailbox settings. HawkOpen deletes its stored sign-in data or password for that mailbox at once and then asks Google or Microsoft to revoke its access; from that moment it cannot send, check or refresh anything for that mailbox.

  • In which webmail does the HawkOpen extension work?

    In three: Gmail, Outlook on the web (including Outlook.com and Microsoft 365 in the browser) and Yahoo Mail. For any other mailbox, connect it to HawkOpen and send tracked emails from the dashboard.

  • Can I see the activity of all my mailboxes in one place?

    Yes. Tracked emails from every mailbox you connect appear together in your HawkOpen history, and you can search them by subject or address and filter them by mailbox. Free includes 1 mailbox, Pro 3, and Business has no mailbox limit.

  • Does HawkOpen sync my mailbox folders and show my inbox?

    HawkOpen has an inbox view for a connected mailbox: it lists the mailbox’s folders and shows a message when you open it, and a folder is refreshed when you ask for it. It does not replace your mail program, and your mail stays with your provider.

  • Can I send tracked emails from a shared mailbox or an alias?

    With Sign in with Google or Microsoft, HawkOpen sends as the account you signed in with. For another address, such as an alias or a shared mailbox, add it as an IMAP/SMTP mailbox with that address and the login your provider gives you; whether the provider accepts sending from that address is up to the provider.

  • Why does my mailbox connection fail?

    For IMAP/SMTP the usual causes are a wrong server name or port, a normal password where the provider wants an app password, or IMAP switched off at the provider. For Google or Microsoft it is usually a sign-in that was not completed, access that was later revoked, or a company administrator who has not allowed the app.

  • Does Google Workspace email log search or Microsoft message trace show whether an email was opened?

    No. These admin tools show the path of a message: whether it was sent, delivered, delayed or bounced. They do not show whether the recipient opened it. HawkOpen records opens and clicks separately, each with a category.

  • Can HawkOpen give me a custom-domain email address for Gmail?

    No. HawkOpen does not sell mailboxes or domains. You connect a mailbox you already have, through Google, Microsoft or IMAP and SMTP, including one on your own domain from any host that offers IMAP and SMTP.
