A couple of Frenchmen in Press Box synonymous with The Mail no one wants (8)
I believe the answer is:
spammers
'box synonymous with the mail no one wants' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'a couple of frenchmen in press' is the wordplay.
I cannot really see how this works, but
'a' is within the answer.
'frenchmen' could be 'mm' (two M's - M is short for Monsieur) and 'mm' is found within the answer.
an anagram of 'press' is 'spers' which is located in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for spammers that I've seen is " They send unwanted emails in bulk".)
