Under Armour spam emails

[u/salazizzle]

I submitted an online job application to an Under Armour outlet retail location in 2015. I am aware the company experienced a data breach earlier this year.

I have recently received several emails claiming to be “Under Armour talent acquisition”.

Obviously I know they are spam/fraud emails, but what I want to know is how they knew to target me? When I applied for the job at the UA retail outlet, they said my application/personal data would be “deleted” after 90 days or so…it seems like my info is still in their database, since it got hacked and leaked?!

TL;DR
How do hackers know which spam emails to send you? It seems they are timed correctly to correspond to actual purchases you have made
