You're spot on. I'm not sure why @Kevin_C and @ShiellaGraceA are telling you that you can't map an invoice item to a deferred revenue account. All you need to do is set up item(s) mapped to a deferred revenue liability account and send it to your customer. That debits A/R and credits deferred revenue. Then, when the customer pays the invoice it debits your bank account and credits A/R. At this point, you still have the credit balance in deferred revenue that you need to move to income. After the marketing event, create a journal entry and debit deferred revenue and credit the appropriate income account and you're good to go.
