Some enema I like to include in correspondence (5)
I believe the answer is:
'correspondence' is the definition.
(electronic correspondence)
'some enema i like to include' is the wordplay.
'to include' indicates a hidden word.
'EMAIL' is hidden in the letters of 'some enema i like'.
'in' is the link.
(Other definitions for email that I've seen before include "Messages between computer terminals" , "Internet-borne communication" , "Post" , "Digital message" , "Electronic message" .)
