You should be able to log into the account with your voucher, but don't think you will get the emails. When we get new passes, we log on with them, then we go to register and they seem to get emails. When I log on it welcomes me by name and tells me when my AP will expire. When We get emails it often will have our name on the email. Sometimes by first name and some time by our family name. Since we've always had an AP (since 1995) I've never logged on with a voucher, so not sure how it recognizes you.
