If they got your email due to to database being hacked, then they most likely would mass send their spam to extend their possible reach.

So far I have not received any email spam since the very beginning of me joining here.

What also happens is that spam mail bots simply send out made up emails to people in the hope they guess them right.

For example, they send emails to fatjoe1@outlook.cok fatjoe2@outlook.com and the list goes on.

All in the hope that one or more of these mails are guessed correctly.
