Hi, hope someone can help. In order to mail out vouchers that can only be used once, I need a unique number to be generated when a user signs up. This is then to be used in a campaign as a voucher code (merge tag). Best would be simple, consecutive numbers. Is that possible? Or any work-around other than doing it manually, e.g. from time to time going in to the list to type one-by one?
Many thanks for any ideas!
