If it's a standalone email you've already sent out, you canquicksend itto the specific contact. Another option would be to set the email toresend only to new contacts, where you'd send to the same list and/or select others, and our system will only target contacts in those lists that weren't part of the original sendout.
If you're trying to create and send brand new campaigns to a single contact at a time, you'd need to just add that contact to a list on their own. That is the only methodology since the scheduling and reporting systems are built for sending emails to multiple people at once.
