When a company asks us “which email solution do you recommend?”, the answer always depends on a preliminary question: where do you want your data to reside?
If the answer is “in Italy, on controlled infrastructure, without depending on American hyperscalers”, then Zimbra becomes the most sensible choice. Not because it’s better than Google Workspace or Microsoft 365 in absolute terms, but because it offers something these solutions cannot guarantee: complete sovereignty over corporate email data.
We’ve been managing Zimbra infrastructures since 2010. In these years we’ve migrated hundreds of companies from on-premise Exchange, from poor quality email hosting, from improvised solutions on shared servers.
