Emails are digital messages sent over the internet, allowing people to communicate quickly and easily. They can include text, images, and attachments, making it simple to share information with others. You can send an email to anyone with an email address, whether they are across the street or on the other side of the world. To send an email, you typically use an email client or a web-based service like Gmail or Outlook. You write your message, add a subject line, and enter the recipient's email address. Once you hit "send," your message travels through the internet and arrives in the recipient's inbox almost instantly.
