| Body | Main content of the email | The actual message text |
| Attachments | Files added to an email | PDF, Image, Word file |
| Signature | Sender's name and contact details | Regards, Rohan Mehta |
💡 Tip: Always write a clear subject line — it helps the receiver understand the purpose of the email.

| Step | Action | Description |
|---|---|---|
| 1 | Open your email service | Gmail, Outlook, Yahoo Mail, etc. |

4. Understanding CC and BCC
| Term | Full Form | Visibility | Purpose |

| BCC | Blind Carbon Copy | Hidden from others | For sending private copies |

Example: If you're sending an email to your
supervisor,
• Add team members in CC (so they are informed)
• Add HR in BCC (so others don't see HR's email)

| Spreadsheets | Excel files | Data sharing |

Think of Email like a digital postal system:
Digital letter

Main receiver's address
CC/BCC
Copies sent to others
Attachment
Enclosed documents
Send Button
Posting the letter
💡 Just like you can't send a letter without an address, you can't send an email without the recipient's email ID!
