How can I know if I am being tracked?Indexup to index

Your email reading habits are almost certainly being tracked by most other organizations that send you email. They didn’t ask for your consent; they just handed your name and email address to an email marketing firm such as MailerLite or MailChimp.

If you are curious to know the technical details of how email marketing corporations put hidden tracking links in your email messages, here is some TL;DR Unnecessary Detail that you can use to see how you are being tracked by these marketing corporations.

How they track your email message openingIndexup to index

An email marketing service tracks when you open your message by hiding a tiny unnoticed 1-by-1 pixel image link in the bottom of each message. That image link points to their service and is coded to match your name and email address, so when you open your email and that invisible image loads, the mailing service knows it was you. That is why many email readers include an option to “not load externally-stored images”, to avoid triggering this image link that reveals information about the message you just opened.

If you use View Source to look at the HTML source of an email message that is tracking you, you will find the tiny one-pixel image at the bottom of the message. It might look something like this (this is from MailChimp):

<img src="https://biodanza.us.list-manage.com/track/open.php?u=3103415e6fe7&id=491de&e=eec8c" height="1" width="1" alt="">

Those numbers on the image link identify you and the message number back to the tracking service. If you don’t load external images, the service won’t know you opened that message.
