Hi there Marketo world,
Have a question for you all. We want to run a program where we issue a coupon code to users. However, once they claim it, we want to block that domain, so that no one at that domain is able to claim that coupon code again.
I know I can look up "not in Smart List" but that is for unique email address, not a domain-wide block. Any ideas on how we can expand that would be much appreciated.
