Affection that may come with email (10)
I believe the answer is:
attachment
I believe this clue is a double definition.
'affection' is the first definition.
(I've seen this before)
'that may come with email' is the second definition.
(as in an email attachment)
(Other definitions for attachment that I've seen before include "what often comes with spam?" , "what might accompany 50 [EMAIL]" , "Fondness" , "Document with e-mail" , "Liking" .)
