Core Syntax & Patterns
The Safe Sender Check
IF the sender is someone I know and trust, THEN it is likely safe to open the email.
Always look at the 'From' address first. Use this rule to decide if you should open the message or ask a grown-up for help.
The Subject Line Clue
Read the Subject before the Body.
The subject is a short summary. It helps you guess what the email is about and decide if it's important to read right away.
The Attachment Rule
Only open attachments 📎 from people you know.
Attachments can be fun, but some can be harmful. If you don't know the sender, don't click the paperclip. Always ask an adult if you are unsure.
