This document compares on-premise hosting versus cloud-based hosting for email solutions. On-premise hosting requires significant upfront costs for servers, software licenses, firewalls, storage and administration. It also has risks of downtime, blacklisting, slow performance and lack of control. WorldPosta offers cloud-based email hosting with large mailbox sizes, Outlook integration, web access, advanced search, security features, controls and 24/7 support at a lower ongoing cost compared to on-premise hosting.
