How to use the internet
Use email.
Email is a lot like regular mail and you can use it in many of the same ways. You'll need to sign up with an email service in order to get an address, though.
Many email services are free and good ones include gmail and outlook.com. When you go to check your email, you will go to the website for the service you signed up with and only the service you signed up with in order to read your mail.
