Definition
Email hosting is a service that runs professional email on your own domain, such as [email protected], instead of a generic gmail.com or outlook.com address. It manages your mailboxes, storage quotas (commonly 15 GB to 50 GB per user), spam and virus filtering, and the mail servers that send and receive messages over SMTP and IMAP. Your domain's MX records point to the host, which handles delivery. Email hosting can come bundled free or cheap with web hosting, or from a dedicated provider such as Google Workspace, Microsoft 365, Fastmail, or Zoho, typically priced from about USD 1 to 6 per mailbox a month. Bundled hosting suits low-volume personal use; dedicated hosting suits businesses that need reliable deliverability, larger storage, and uptime guarantees. Keeping email separate from your website means a server outage, migration, or attack on one does not take down the other.
How it works
Email hosting provides the mail servers and mailboxes tied to your domain. Your domain MX records point to the email host, which receives incoming mail and stores it, and provides outgoing (SMTP) sending. You access it through webmail or an app over IMAP.
Why it matters
A branded email address signals legitimacy and builds trust far more than a free personal address. Dedicated email hosting also delivers better deliverability, storage, and uptime than the basic mail bundled with cheap web hosting, and separating the two protects each.
