Too late? It seems somehow they retrieved physical emails back in the day, before everyone removed their mails from LI. Now they're hitting mail directly but somehow still aware of your current LI profile. I assume they have an aggregated DB connecting everyone's socials together with physical mails which they share or even sell to each other?
