Returns the SMTP log for a specified recipient of a specified email campaign
This method only retrieves SMTP logs for broadcast email marketing campaigns. We are working on a method to retrieve SMTP logs for transactional email messages as well, but this poses some challenges not seen with broadcast campaigns. For example, while broadcast campaigns generally don't have duplicate email addresses, it is very possible that in a Transactional Group's email messages, a single email address has received multiple transactional messages over time. Thus, simply passing in a Transactional Group Name and an email address won't suffice for retrieving the log, since the API needs to be able to determine the time range of logs to search in order to display them to the caller.
