Italian numbers break Indian CRMs in two ways. A Turin landline written the domestic way, 011 000 0001, is refused, which is the honest answer: without the country there is nothing safe to guess. A mobile written as 333 000 0002 is worse, because it passes. A generic rule assumes the digits already begin with a country code and returns +33…, which is France.
Italy also differs from the UK on the 0. In London the 0 of 020 disappears after +44; in Turin the 0 of 011 stays after +39, so an office number is +39 011 …, never +39 11 …. A rule copied from British practice that deletes a written (0) will break every Italian landline it touches.
The fix sits in your own data, before the send: ask for the country on the form, store every contact in E.164, and clean old imports from trade fairs and spreadsheets before the first broadcast.
