You can create a custom email body text (in either TXT, HTML or both) using captions and Variables (see foot of Modify > Log > Email Log > Advanced settings page) and optionally suppress the mailing of the actual log. But while you can add counts/totals, etc, you cannot add entries per-file or list success/error at the file-level (only 'how many', if any). Bear in mind there could be hundreds of thousands of per-file entries, which would likely overwhelm the mail system (or be rejected)
There are numerous Variables you can use - details in the Help. Bear in mind you need to add your own captions (in whatever language you like).
There's no summary (group-level) functionality. It doesn't 'fit' well with how groups work internally, I gather. It may still be on the ideas list (I don't have that - but I do know it's a very long list...) but no promises or ETA, sorry.
