Domains & Email Guides

A domain, website and email service are related, but they are not the same product. Understanding where registration, DNS, hosting and mail delivery are controlled helps prevent broken websites and email outages during setup or migration.

Start with a domain you can keep

Use Domain Search to check availability and read How to Choose a Domain Name before buying solely on price. A good domain should be easy to say, spell and remember, with an extension that makes sense for the business.

If you are new to registration, How to Buy a Domain Name explains the purchase process and the difference between registration and hosting.

Domain registration and web hosting are separate

Your registrar controls the domain registration; DNS tells internet services where the website and mail should go; web hosting serves the website. Read Domain vs Hosting if you are unsure which part you need to change.

Professional email needs a domain and the right DNS records

For company mailboxes, compare Professional Email Hosting and Microsoft 365 Email. The Domain & Email Hosting guide walks through domain ownership, mailbox creation and DNS.

Do not change MX records until the destination users/mailboxes are ready. The MX record guide explains why provider-specific records and authoritative DNS matter.

Plan domain transfers before they become urgent

Transfers can involve registrar locks, authorization codes, approval emails and timing rules. Start with Transfer a Domain and How Long Does a Domain Transfer Take? before moving a business-critical domain.

Choose email plans around users and workflow

Mailbox size is only one factor. Decide whether users need professional email only, browser-based productivity tools or installed desktop applications. Use Microsoft 365 vs Business Email and confirm current plan details in the live product details before checkout.

Keep DNS changes documented

Record the current nameservers and important DNS records before making changes. For a production domain, change one thing at a time where possible, understand propagation, and keep access to the old service until website and email routing are verified.

Domain extensions and current offers

When the brand requires a specific extension, compare .US domains and .cloud domains. For price-sensitive registration searches, review the current affordable domain options and domain offers; verify live registration and renewal terms before checkout.
