Easy-SMTP, ReachMail's email relay service, has it's own set of reporting features. You can view/export delivered,open,click,opt out, and bounce data with just a few clicks.
Filter by date range, search for individual recipient address or pull the report by x-rm-campaign in order to focus your search on relevant information.
For more information about setting an x-rm-campaign header on your message, and thus tagging several messages as part of a single campaign, see here.
