I have mine set to 'no'. No, no, no.
At onetime, they had the secret 'Do Not Contact' setting ... extra protection ... only purchase receipts, and similar.
But today, I made the mistake of buying a couple books, and here comes a share-code email. I don't even recommend Logos, except to those who already have it.
Maybe a refund is in order ... probably another share-code.
BTW if you go to the Logos.com menu, logged in, to check email subscriptions, it plays like it doesn't know you. If you go to Account > Profile, it does.
