I confirm receipt of your email and will be in touch shortly.
'Farò' = fa-RÒ; stress on the final syllable (simple future).
Use to acknowledge an email when you cannot reply fully immediately, signalling that you have received it and will respond properly soon.
'Farmi vivo/a' (to make oneself heard/to be in touch) is an idiomatic expression meaning to get back to someone. 'Vivo' for men, 'viva' for women. It is a warm, slightly informal phrase that works well in semi-formal contexts.
Ho ricevuto la sua email e le rispondo al più presto.
I have received your email and will reply as soon as possible.
More formal; avoids the idiom
Grazie per la sua email; la ricontatterò entro oggi.
Thank you for your email; I will contact you again by today.
Sets a specific timeframe
Email ricevuta, grazie! Ti rispondo domani.
Email received, thanks! I'll reply tomorrow.
Very informal; for colleagues only
Sending a brief acknowledgement is standard good practice in Italy. Leaving an email completely unanswered — even for a day — can cause anxiety and follow-up calls. A quick 'ricevuto, rispondo presto' (received, replying soon) prevents this.
