'Riguardo' = ri-GWAR-do; the 'gua' sounds like 'gwah'.
Use to open an email to an external party when you need information about a product, service, or administrative matter.
'Vorrei' (I would like) is the conditional of 'volere' and is significantly more polite than 'voglio' (I want). 'Richiedere' is more formal than 'chiedere'. Together they create a respectful, non-demanding tone suitable for first contact.

Italian companies, especially smaller ones, often prefer a phone call for initial enquiries. If you email cold, keep the message concise — lengthy first-contact emails are less likely to receive a prompt response.
