A name. A conversation.
A place to build.

Keep the address under control.

A domain connects your public identity to the services behind it. Confirm the registered contact, account access, renewal arrangements and who manages authoritative DNS. The registration and the website can be separate services.

Before changing providers, identify nameservers, existing DNS records and transfer requirements. A domain transfer need not mean moving email and hosting at the same moment.

Plan the whole mail journey.

List users, aliases, shared addresses and the devices that need access. Review mailbox capacity, retention and recovery requirements alongside the applications that send mail using your domain.

Preserve the correct MX records. Review SPF for authorised senders, configure provider-issued DKIM and introduce DMARC with monitoring and an appropriate policy. Authentication and reputation both matter; no configuration guarantees inbox placement.

Fit the hosting to the application.

The original Mailbox site describes cPanel hosting, scripting and database options. Confirm the currently supported runtime, database version, resource limits and management scope for your application before ordering.

Agree responsibility for site updates, certificates, access, backups and restore testing. A hosting account is an environment; keeping the website healthy is an ongoing set of tasks.

A useful brief is a better starting point.
