How do spammers know an email is active?

491 views

I recently put my old Hotmail account on my phone, which I traditionally only checked a few times a year. I went from 1-2 spam emails every few months to several a day, after going through all the old ones and marking them as spam. How is this possible? I haven’t given this email out in years, and none of my monitoring services have flagged this email recently. It seems spammers somehow know this email is active again.

There’s a pretty basic extension that’s free called mailtrack. It just embeds software into each email you send to see if a person has received, and/or opened an email. I use it for business emails when I’m expecting a response. I’m sure there’s a more complex version of this that can track an entire email account to some degree
