I will also send my request in writing, if you find it useful.
'Iscritto' = is-CRIT-to; stress on the second syllable; 'sc' before 'r' is unvoiced.
Use after a verbal salary discussion to formalise the request and create a record, particularly useful in larger companies with formal HR processes.
A written request ('richiesta scritta') creates an official record. In Italy, putting things in writing ('mettere per iscritto') is a sign of seriousness. It also prevents the manager from claiming the conversation never happened. Email is perfectly acceptable for this purpose.
Le mando una email riepilogativa di quanto discusso.
I will send you a summary email of what was discussed.
Follow-up email after verbal discussion
Posso formalizzare la richiesta attraverso i canali HR?
Can I formalise the request through HR channels?
For companies with formal HR processes
Le lascio un documento scritto con i miei dati e la mia richiesta.
I will leave you a written document with my data and my request.
Printed document approach; old-fashioned but still used in traditional companies
In Italian companies, a manager often needs to justify a salary increase to their own manager or to the owner. Providing a written summary with data makes their job easier and increases the likelihood of approval — you are helping them make the case for you.
