What is mail id

A mail ID, also known as an email address, is a unique identifier used to send and receive electronic mail (email) messages over the internet. It is a string of characters, typically consisting of a username and a domain name, separated by the @ symbol.

The format of a mail ID is usually in the following format:

username@domainname

For example:

Here, john.doe is the username and example.com is the domain name. The @ symbol separates the two parts.

Mail IDs are used to identify the sender and recipient of an email message. When you send an email, your mail ID is used as the "From" address, and the recipient's mail ID is used as the "To" address.

Mail IDs are used for various purposes, such as:

  1. Sending and receiving email messages
  2. Creating online accounts, such as social media profiles or online banking accounts
  3. Registering for online services, such as newsletters or online courses
  4. Contacting individuals or organizations for business or personal purposes

Mail IDs are managed by email service providers, such as Gmail, Yahoo, Outlook, or custom domain name registrars. They can be used on various devices, including computers, smartphones, and tablets, using email clients or web-based email services.
