Contacted when Everyman's beginning to get bothered about Frenchman (1-6)

'contacted' is the definition.
(I've seen this before)

'everyman's beginning to get bothered about frenchman' is the wordplay.
'beginning to' suggests taking the first letters.
'get' says to put letters next to each other.
'bothered' becomes 'ailed' (I've seen this in another clue).
'about' says to put letters next to each other.
'frenchman' becomes 'm' (abbreviation for Monsieur - like 'Mr').
The first letter of 'everymans' is 'e'.
'ailed' put after 'm' is 'mailed'.
'e'+'mailed' is 'E-MAILED'.

'when' acts as a link.
