email
Email, or electronic mail, refers to a message or messages sent from one computer to another over a network (email also signifies the process of transmitting these messages). When you choose a Yahoo! ID and password, you get access to Yahoo!'s free email service. Additionally, if you have a Yahoo! Domains plan, you can take advantage of email forwarding, which allows you to set up an email address at your domain. With Yahoo! Web Hosting, you'll get Business Mail or Personal Address, both of which allow you to create personalized email addresses based on your own web address, among other features. Learn more.
email account
An email account is, technically, a password-protected repository for email where a user can receive, access, and store mail; in other words, it's the means through which you can engage in and manage your email correspondence. An email account includes one mailbox and one or more unique email addresses. A Business Mail plan allows you to create more than 2,000 individual email accounts, each with a unique email address that matches your domain, or web address. Learn more about Yahoo! Business Mail.
email address
An email address is a unique address (such as you@yourdomain.com) used to receive and send email to a particular destination. An email address may correspond to a mailbox, where you store and retrieve your messages, or a mail forward, which acts as an extra address for a mailbox. Learn more about Yahoo! Business Mail.
email forwarding
With a Yahoo! Domains plan, you'll get email forwarding, a feature that allows you to set up an email address that includes your domain name, such as jane@learn2yoga.com. Messages sent to this address will be delivered to your free Yahoo! Mail inbox. Learn more.
extension
A domain extension is the suffix at the end of a domain name, such as .com, .net., or .edu. If your domain name is widgetdesigns.com, for example, your domain extension is .com. Each extension represents a web site category or a country. The extension .org, for example, stands for organization and is typically used by noncommercial web sites. Extensions like .uk (United Kingdom) and .ca (Canada) are used in domain names registered in their respective countries. Learn more.
