Maiden going to resort getting lots of unwanted correspondence (4)
I believe the answer is:
spam
'unwanted correspondence' is the definition.
(as in spam emails)
'maiden going to resort' is the wordplay.
'maiden' becomes 'm' (cricket abbreviation).
'going to' is a charade indicator (letters next to each other).
'resort' becomes 'spa' (spa is a kind of resort).
'm' put after 'spa' is 'SPAM'.
'getting lots of' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for spam that I've seen before include "Tinned processed meat" , "unsolicited messages" , "Possible item from menu" , "email messages" , "unwanted correspondence" .)
