Awaiting your kind reply,
'Riscontro' = ris-CON-tro; stress on the second syllable.
Use just before the sign-off when you need a reply. It politely signals that you expect a response without being pushy.
'Riscontro' in the business sense means 'reply' or 'feedback'. It is more formal than 'risposta'. Adding 'gentile' (kind) softens the implied request for a reply. This phrase is extremely common in Italian professional emails.
In attesa di una sua risposta,
Awaiting your reply,
Slightly less formal; 'risposta' is simpler
Resto in attesa di un suo cenno,
I await a word from you,
'Cenno' means a brief sign or word; very polite
Confido in una sua rapida risposta.
I trust in a prompt reply from you.
More assertive; use when urgency is implied
Italian business culture does not always expect immediate email replies. It is common to wait 24–48 hours. Sending a follow-up after one day can be seen as impatient; two to three business days is more appropriate.
