Imagine that inside your mailbox \u2014 the one for snail mail, that is \u2014 a camera is monitoring which flyers you read and which ones you chuck out without a second glance. You might never have pondered it, but e-mail provides the creators of spam and ad mailings that very ability.<\/p>\n

Throughout its existence, e-mail has evolved: from simple text to eye-catching messages incorporating all kinds of fonts, styles, and embedded images. In terms of capabilities, e-mails are now similar to Web pages, meaning that senders can embed elements in messages to track what\u2019s happening in your mailbox.<\/p>\n

How does e-mail tracking work?<\/h2>\n

Researchers from Princeton University analyzed about 1,000 ad mailings<\/a>. They found that 70% of the messages contained ad trackers\u00a0\u2014 automatically downloading elements such as invisible images that not only inform the sender when and how many times you opened the message, but also transmit personal data (for example, your e-mail address) in the query string. What\u2019s more, the tracking domain query reveals your IP address, from which your approximate location can be determined.<\/p>\n

Such technologies allow the creators of ad mailings to target their messages more effectively. For example, tracking is extremely useful for so-called A\/B testing<\/a>, which helps determine which message topics and types (say, with or without emojis) people are more likely to click. On top of that, ad trackers can store browser cookies so as to \u201crecognize\u201d you on other sites that are not even related to the mailing topic.<\/p>\n

That way, the advertising network gets more information about your interests, and they can sell that information to advertisers. For example, if you opened a message about discounts on sneakers, sports footwear ads could start hounding you online.<\/p>\n

How to protect yourself<\/h3>\n

If you use the Gmail webmail client, you\u2019re ever so slightly in luck. This provider (and possibly some others as well) download all images from the message to their servers before passing them to you. That means advertising networks can\u2019t store cookies in your browser or learn your IP address \u2014 unless they pay Google for the information.<\/p>\n

Users of other e-mail providers also have some good news: Tools for blocking Web trackers<\/a> work pretty well for e-mail tracking too, and you can use a VPN<\/a> to hide your real IP address.<\/p>\n

Here are a few tips to help protect against being tracked through your e-mail:<\/p>\n
