As a Stripe Atlas customer, I received a snail mail letter from Stripe about this issue. It included some suggestions from them to prevent identity theft.
As I texted a tech friend of mine: if I’m receiving a physical letter from a leading tech co like Stripe, then it’s at least a moderately serious issue.
Google sends Google adwords ads with physical letters in Germany at least.
What does it mean to send an "adwords ad"? Has Google branched out from digital advertising and started distributing ads via the mail?
A solicitation to join adwords, often including an offer to run a certain amount (ex. $100 worth) of free ads for new users
