Best regards,
'Cordiali' = cor-DYA-li; the 'ia' blends into one quick sound.
Use as the standard sign-off for most formal and semi-formal business emails. It strikes the right balance between warmth and professionalism.
'Cordiali saluti' is the Italian workhorse sign-off, equivalent to 'Best regards' or 'Kind regards'. It replaced the older and more verbose 'Distinti saluti' in everyday correspondence. Always put a comma after it, then your name on the next line.
Distinti saluti,
Yours sincerely / With distinguished regards,
More formal; used for officials and senior figures
A presto,
Talk soon,
Informal; fine for colleagues you know well
Buona giornata,
Have a good day,
Friendly and increasingly popular in internal emails
In Italy, signing off with just 'Saluti' (without 'cordiali') can occasionally be read as curt. When in doubt, use the full 'Cordiali saluti' to keep the tone warm and professional.
