New hosting depends on platform suitability, support and licensing checks. A listed rate does not create a mailbox or authorize a migration.

What your budget buys
Know the whole mailbox bill before you move
CRU prices the mailboxes and domain charge openly, with a named service contact and a separately agreed migration plan. Filtering is a separate choice, so the starting mailbox price does not hide its required domain component.

Filtering requires both its domain and mailbox components. Add this optional amount to the hosting example if selected; filtering alone does not host mailboxes.

What to account for
CRU · Hosted email Basic
$6 / mailbox / month50 GB per mailbox, plus $10/domain/month. Migration, device setup, filtering and additional software are separate unless included in the quote.
Five Basic mailboxes on one domain total $40/month, or $480 for 12 months, before migration or other services.
A lower per-user hosting rate. CRU Basic is $6/mailbox/month plus $10/domain/month; migration, filtering and support scope must be compared separately.
Choose the mailbox platform that fits your business, then add only the migration, filtering and support you need. CRU can help with its accepted hosted-email scope or a Microsoft 365 migration; the lower Microsoft license price remains a useful benchmark.

Before you get started.
Do I have to move to CRU-hosted email?
No. The assessment can result in a configuration or migration project on a suitable third-party platform. Licensing and the destination are agreed before work.
