I have come across a couple of strange email addresses and have thought about this blog post for a while now. What worries me the most is the fact that some of those email addresses are forwarded to employers and they bounce.
Email addresses are mostly free from an Internet service provider or from one of the many free web-based email services such as Gmail, Yahoo! Mail, and Outlook.com.
Your email address is unique in all the world, like your postal address or phone number is unique. Capital letters are not necessary when writing your email.
An email address will look like this: [email protected]
The @ sign indicates the break between the username and the domain name. Everything after the @ sign is the domain name, which indicates the mail server.
