How to block email tracking pixel on iPhone, iPad, and Mac

Companies and ad agencies have a way of tracking emails they send to you; so they know when you open them. And worse, they use email tracking pixels to capture your mailing activities, monitor email engagement, behavioral trends, and more.

But let’s face it, not all the data they collect is used for positive purposes; there are some nefarious activities involved. So, whether you’re using Apple Mail, Gmail, Microsoft Outlook, or any other mail client, it is wiser to stop email tracking on iPhone, iPad, Mac, or PC right now.

How does email tracking work?

Before we move on, let’s first briefly understand the email tracking concept. A tracking pixel, email tracking pixel, spy pixel, or just pixel is the digital marketer’s fancy way of tracking a user.

Companies that use email marketing campaigns to engage audiences need to know if the sent emails are being read. So they slyly embed tracking pixels (a small image created using an HTML code) into the mail.

What is a tracking pixel and editing a tracking code

As you open an email or a webpage, that image, aka pixel, is downloaded to your phone or computer. This helps return a ‘flag’ to the server hosting the image, letting the sender know whether the webpage, email, or document has been opened.

Since the size of the tracking pixel is often in bytes, it’s downloaded in milliseconds, even in a low-internet speed zone.

Why should you block email tracking?

Well, firstly, privacy, Duh! Secondly, consent.

Secretly embedded into emails and webpages, tracking pixels violates users’ privacy. It allows the data company to collect a variety of information about your online behavior, including

  • Type of operating system being used — can target ads based on your mobile’s OS.
  • Website visiting time or email reading time — shows your intent.
  • Type of email or website used (on desktop or mobile).
  • Type of client used (a mail program or browser) — can target different pricing for different users.
  • IP address — potentially, location as well.
  • Activities on the site during a session — shows your interest on the site’s landing page.
  • The screen resolution of clients.

Now, doesn’t this all scare you? Well, they do say prevention is better than cure. So let’s move on and learn how to stop this email tracking activity on your iPhone, Mac, or PC.

Email trackers can be intrusive since they monitor your email activities, including the types of emails you respond to and the websites you visit. Preventing it on most email apps is easy, thanks to their built-in email tracker blockers.

However, note that while these apps offer built-in features, the blockers in some are weak against trackers. But Apple’s Mail app, Gmail, and Outlook do excellently at blocking Apple’s pixels.

Did you get those trackers blocked? Let me know in the comments section below.
