Bottom line
A business should use a managed mailbox provider or a well-supported hosting email service and configure SPF, DKIM, and DMARC. Forwarding alone is not a complete sending and authentication design.
DNS changes can interrupt mail. Inventory every address, alias, group, application sender, and recovery account before migration. Before adoption, separate essential requirements from optional features and verify user limits, billing terms, add-on costs, permissions, data export, migration procedures, and support scope. Use any free plan or trial to reproduce a realistic workflow with the actual administrators and users, including the ongoing governance burden. Recheck the provider’s current official terms immediately before purchase.
