Crossword Genius

The audience sees red ads probably (10)

Ross

I believe the answer is:

addressees

I'm a little stuck... Click here to teach me more about this clue!

'the' is the definition.
I can't tell whether this defines the answer.

'audience sees red ads probably' is the wordplay.
'sees red ads' anagrams to 'ADDRESSEES'.
But, I am not clear how this is indicated.

Can you help me to learn more?

(Another definition for addressees that I've seen is " Group getting letters".)

I've seen this clue in the Sydney Morning Herald.
