I got an email with the code approx 5 weeks after registration the email is titled "[YOURNAME], your bulb offer is ready" and from this address <no-reply@m1.email.samsung.com> so if you add this email to your contacts it usually prevents it going to spam. I'm not sure if it makes any difference but may also be help if you use the same email address to register accounts with samsung and bulb. The helpdesk for samsung smartthings have been very helpful with code issues and similar queries but at the moment with covid virus they are on limited staff so its taking longer to respond to queries and being patient is just part of it and i know how frustrating it is but the community pages on smartthings and bulb are full of people who know how to help with some things.
