Automatically send an email when you visit the site?

Question

Marketing

Found a very interesting feature.
I went to one site, left, and after a while, a letter from this site came to the mail from mail.ru with an advertising offer. At that moment I was logged into mail.ru.
What kind of service or script?

Answer 1

Hello.
I draw your attention to the fact that this is not possible. This is a violation of the law on personal data. There are a number of methods when you can read the client's cookies, understand what social profile is associated with him, and so on, but this is illegal. If desired, such a site can be taken by bells, so be careful.
It is better to use the notification technique that browsers now allow you to do.

Answer 2

I once asked the same question))) I
went to the site - I received a letter, how so?

Through the mail.ru API, probably.
