Email Hosting Explained
What email hosting includes
Email hosting is a service in which a provider runs the mail servers that receive, store and deliver email for your domain, so you do not have to operate that infrastructure yourself. You choose a service, add the mail settings it gives you to your domain, and create mailboxes for the people who need them.
A mail server is software that runs all the time on a machine connected to the internet. It must accept messages from other servers at any hour, keep them safe until someone reads them, and send your outgoing mail reliably. A hosting provider handles this work, along with the supporting tasks that keep mail usable.
A typical email hosting service includes:
- Mail servers that accept, route and send messages for your domain.
- Mailbox storage so messages stay available from any device.
- Spam and virus filtering that screens incoming mail before it reaches the inbox.
- Access options, such as a web interface and the standard protocols
IMAPandSMTPfor desktop and phone apps. - Backups and an admin panel for adding users, aliases and settings.
To see how a message travels between these servers, read how email works.
The main types of email hosting
Email hosting comes in several forms. The right one depends on how many people use email, how much control you need and whether your mail is tied to a website.
- Bundled with web hosting. Many hosting plans include a set number of mailboxes on the same server as the website. This is the simplest option for small sites, but the mail shares resources with the site.
- Dedicated email hosting. A service that runs only mail, with its own filtering, storage and support. Mail stays separate from the website.
- Business suites. Platforms such as Microsoft 365 and Google Workspace combine email with calendars, file storage and office apps. Mail is one part of a wider set of tools.
Bundled mail is not always enough once volume grows. The trade-offs are covered in email hosting vs web hosting.
A small studio outgrows its bundled mailbox
A three-person design studio runs a brochure website on a shared hosting plan that includes mailboxes. At first, the bundled mail is enough. As the studio grows and starts sending invoices and project updates to clients, a busy website or a sending limit could interrupt messages. Moving mail to a dedicated email service lets the studio keep its website where it is while mail runs on its own infrastructure.
Frequently asked questions
Is email hosting the same as web hosting?
No. Web hosting stores and serves website files, while email hosting stores and delivers messages. The two can be bought from the same provider and can share a server, but they are separate services with their own settings and risks.
Can I use my own domain for email hosting?
Yes. Most providers let you create mailboxes under your own domain, such as [email protected]. You add the mail records the provider gives you to the domain's DNS settings, the records that tell the internet where to send mail for the domain. After that, mail for the domain is routed to the new service.
