I've been getting these e-mail, too, or at least very similar ones. I posted
a screenshot of one last month, and I'm still receiving them nonstop.
The weird thing is that they've come to at least two different e-mail accounts that I have, and I don't remember providing Ledger with even one . The other weird thing is that people still trust this defrocked joke of a HW wallet company and still buy their wallets....but that's another story.
