'Disposizione' = dis-po-si-TSYO-ne; the 'zi' sounds like 'tsee'.
Use near the end of a formal email to signal openness and helpfulness. It is one of the most common closing formulas in Italian business writing.

Rimango a tua disposizione.
I remain at your disposal.

Simpler and more modern phrasing
