How did browsing an online seller give them my email? Login/Join

I browsed a big online gunshop for a rifle. To see the price I had to put one in my cart and proceed to check-out. At that point they wanted me to log in. Instead I just emptied the cart and went on my way without providing any information.
Today they sent me an email informing the rifle is back in stock. It was for specifically that rifle, not an add.
How did they connect my activity with my contact info? I browsed with a MacBook Air using Safari on my Verizon 5g cellular/wifi service.

Have you shopped with them in the past? (completed a purchase)
If so, cookies.

Did you browse from chrome while logged into your google account?

Or something similar?

Scary world out there.

How did you start the browsing session with them? For example, if you clicked on a link from your email that'd be how they obtained your email.

Mancuso [powersports dealer, for those not in Houston] got on my spam list.
I browsed their inventory, either directly or from a CL link & started getting 'look what we have this week' emails, regularly. Not PSA frequent, but at least 2 a week.
Gmail spam filter does a good job of catching them.

Most likely simple correlation, e.g:

  • Matching your IP address with data purchased from a data aggregator (or your ISP)?
  • Cross-site cookies?
  • An automatic "account login" attempt by your browser?


I am sure that the AIs used by spammers who do this kind of thing have figured out other avenues.

Defense? I know only that my "automatically send these to trash" e-mail filter grows by the day. Aggressive use of "plus addressing" can help in identifying who "shared" your information, but stopping it is another matter.

Many people don't realize where those emailed advert links lead. Many of them lead, not to the vendor's site, but, to an advert-tracking service, which logs the successful "hit," then takes you to the vendor's site.

Yup. One of the many advantages of using "plussed" (aka: "tagged") email addresses.

Here's how that aspect of tagged email addresses works:

Say you've created an account at We Be Firearms and gave them the tagged email address "nobody+wbf@example.com." You get an advert from Firearms backwards-R Us. You look and see it was sent to your "nobody+wbf" tagged email address. Now you know We Be Firearms either sold their mailing list or their customer database was hacked.

In the case of the OP, if something like that happened, he clicked on the advert, tracking cookies were deposited in his browser's cookie store, and the advertising store associated his email address with what he looked at.

I do get the occasional “sale” emails and I do click on the links. That is probably the connection. Cookies or whatever. I did buy a rifle online from them a few years ago. I guess I need to learn how clear cookies on my MacBook.

I very rarely click links in e-mails as there are way too many spoofers that get past the e-mail spam filters.

Instead, if I see an e-mail for something that interests me then I go to my bookmarks and open the site from there. Eliminates the chance of getting scammed and eliminates all of the tracking BS that comes from the e-mail link (i.e. they won't have your e-mail address).

BTW, these are the first 2 steps in clearing your cookies in Safari:


If you want Safari to autmatically clear cookies every day then these are the steps:
1.

2.

Four weeks ago or so, I went into an Ice cream/coffee shop. I was going to pay cash but the owner (seemed to be a nice guy) was training a young lady and asked if I would use a credit card instead so as to teach her how to process that form of payment.
Sure, no problem.

Some weeks later I got an advertising email from that shop. Probably coincidence.

ETA: I don't have a smart phone but may have had my kindle on internet mode in the car. It connects to Xfinity.

I don't know.

Did you click “accept all cookies” when asked. That includes marketing information which often provides your email.

Always reject or choose “only necessary”

I have a program that regularly cleans out my cache and cookies. It works because I have to also reverify my bank log ins as in "trust this machine?"

I have noticed that when I go to a site to just browse and look at a particular item at a place that has my email address before, after I close the browser and after a while, I get an email saying "did I forget something?" or something like that and it sends me a link to what I was looking.



"It did not really matter what we expected from life, but rather what life expected from us. We needed to stop asking about the meaning of life, and instead to think of ourselves as those who were being questioned by life – daily and hourly. Our answer must consist not in talk and meditation, but in right action and in right conduct. Life ultimately means taking the responsibility to find the right answer to its problems and to fulfill the tasks which it constantly sets for each individual."

I just configured a new Win 11 laptop. Trying to make it secure as possible for a highly "non-secure" type user, here's what I did: 1) pay for vpn with automatic wifi cutoff if the vpn is broken, 2) secure browser in "private" mode, with max restrictions against exploits (though I'm not an expert on windoze exports over the net), 3) installation and config of a password manager, with custom macros to automatically enter username and passwords into all the crazy apps said user uses, with auto-type obfuscation.

Not sure what else I can do at this point, but if I new I'd try it.

From my experience online security is a tough nut to crack.

My work laptop is extremely secure yet still easy to use. It is managed remotely by security professionals and security vendors, and if I knew how they did it themselves I'd do it on my own computers. But, I don't use if for personal use, though nothing that I'm aware of will stop it, since I use it on my company vpn to go outside the company boundary layer all the time for technical research and vendor and consultative support.
