'uncalled-for correspondence' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe there's a link between them I don't understand?

'for correspondence' is the wordplay.
'for' becomes 'dead' (I can't justify this - if you can you should believe this answer much more).
'correspondence' becomes 'letter' (I've seen this before).
'dead'+'letter'='DEAD-LETTER'

Can you help me to learn more?

(Other definitions for dead letter that I've seen before include "no longer observed" , "Unresponsive landlord" , "Law no longer enforced" , "Ineffective rule" , "Itll not lead to prosecution" .)

I've seen this clue in The Globe and Mail and The Telegraph.
