There's no direct means of deleting-but-not-deleting messages. Deleting messages is a global operations, as far as most mail clients and most mail servers are concerned. Mail clients go to some length not to discard a deletion, as well; to communicate and resynch with the mail server if communications should be lost.
- The entries could be (and will be) marked as read (or explicitly marked as unread, if desired), and that can be used to evaluate whether or not the messages should be reprocessed elsewhere. iOS doesn't have any flagging.
- The entries could be relocated, though the folder would have to be on the server and not on the local device.
- The messages you read and delete could have been previously explicitly duplicated somewhere else outside the purview of the client device (either by rules on the mail server, or some rules run by an always-on OS X client that always has mail running), and the duplicate would be kept when the client deletes the message.
- You could migrate to a customer relationship management (CRM) system or to some other server or message-management software that better meets your specific message-handling needs.
- Find or have created a custom message-caching mail client.
- If this is OS X, duplicate the message into another folder using a rule, then delete either the copy or the original at will. (iOS does not have message-processing rules.) OS X also has all sorts of coloring and flagging options available.
There might be some other approaches...
