So I invested some money into crypto and I started receiving e-mails from scam "Bitcoin investors", "metamask support", "trust wallet support" etc. How do they know that I use those? I don't think everyone gets these kind of email's so where does the sender of the email know from that I use these different services? Does anyone here care to explain how something like this works like?
