If you got an e-mail (or a few) from Lutz Ziob, our Microsoft Learning General Manager, about your welcome kit (or kits), that was from us, yes. Our fulfillment vendor sent it, that is why it did not come from firstname.lastname@example.org. In related news, I do not recommend saying "I like your hustle" to your general manager when you pass him in the hallway. In retrospect, you might think think to yourself, that it was kind of a dumb thing to say.
But this just in: I like your hustle.
