“I JUST CAME across this email,” began the message, a long overdue reply. However I knew the sender was lying. He’d opened my email nearly half a year ago. On a Mac. In Palo Alto. At night.
I knew this because I had been running the email tracking service Streak, which notified me the moment my message have been opened. It explained where, when, and also on what kind of device it was read. With Streak enabled, I felt such as an inside trader whenever I glanced at my inbox, privy to details that provided me with maybe a little too many details. And I certainly wasn’t alone.
There are some 269 billion emails sent and received daily. That’s roughly 35 emails for all on the planet, every single day. Over forty percent of the emails are tracked, based on a report published last June by OMC, an “email intelligence” company which builds anti-tracking tools.
The tech is pretty simple. Tracking clients embed a line of code in the body of an email-usually in a 1×1 pixel image, so tiny it’s invisible, but also in elements like hyperlinks and custom fonts. Whenever a recipient opens the email, the tracking client recognizes that pixel has been downloaded, in addition to where as well as on what device. Newsletter services, marketers, and advertisers have used the technique for years, to collect data regarding their open rates; major tech companies like Facebook and Twitter followed suit within their ongoing quest to profile and predict our behavior online.
But lately, a surprising-and growing-number of tracked emails are being sent not from corporations, but acquaintances. “We have already been in touch with users that were tracked by their spouses, business partners, competitors,” says Florian Seroussi, the founding father of OMC. “It’s the wild, wild west on the market.”
According to OMC’s data, a complete 19 percent of all the “conversational” email is now tracked. That’s 1 in 5 of the emails you get from your friends. And you also probably never noticed.
“Surprisingly, as there is a vast literature on web tracking, free email tracker has seen little research,” noted an October 2017 paper authored by three Princeton computer scientists. All of this signifies that huge amounts of emails are sent each day to huge numbers of people that have never consented in any respect to become tracked, however are being tracked nonetheless. And Seroussi believes that some, at least, have been in serious danger as a result.
As recently because the mid-2000s, email tracking was almost entirely unknown towards the mainstream public. Then in 2006, an earlier tracking service called ReadNotify made waves whenever a lawsuit said that HP had used the item to trace the origins of a scandalous email which had leaked to the press. The intrusiveness (and simplicity) of the tactic came as something of the shock, although newsletter services, salespeople, and marketers had long used email tracking to gather data.
Seroussi states that Gmail was the ice breaker here-he points to the period when sponsored links first started turning up in our inboxes, according to tracked data. At that time it seemed invasive, even unsettling. “Now,” he says, “it’s common knowledge and everyone’s fine by using it.” Gmail’s foray was the signal flare; when advertisers and salespeople realized they too could send targeted ads based on tracked data, with little lasting pushback, the practice grew more pervasive.
“I do not know of any single established sales team in [the online sales industry] that fails to use some kind of email open tracking,” says John-Henry Scherck, a content marketing pro as well as the principal consultant at Growth Plays. “I think it will likely be a matter of time before either everyone uses them,” Scherck says, “or major email providers block them entirely.”
That’s partly to do with spam. “Competent spammers will track any activity on your email simply because they often buy entire lists of addresses and can actively try to eliminate spam traps or unused emails,” says Andrei Afloarei, a pnifcc researcher with Bitdefender. “If you simply click any link in one with their messages they will know your address will be used and may actually cause them to send more spam the right path.”
But marketing and web-based sales-even spammers-are no longer responsible for the majority of the tracking. “Now, it’s the key tech companies,” Seroussi says. “Amazon has become using them a lot, Facebook has been utilizing them. Facebook is the top tracker besides MailChimp.” When Facebook sends you an email notifying you about new activity on your account, “it opens an app in background, and today Facebook knows where you stand, the product you’re using, the final picture you’ve taken-they get everything.”
