 Once you retrieve messages from a folder using methods like `$inbox->messages()->get()`, you'll receive instances of the `Message` class.
 
 This class offers a rich set of helper methods for interacting with individual emails, making it easy to inspect, modify, and manipulate messages.

-##### Message Manipulation
+#### Message Manipulation
 
 Beyond just flagging, you can move or copy messages between folders, or even delete them:
 
 - `copy(string $folder, bool $expunge = true)`: Copies the message to the specified folder.
 - `move(string $folder, bool $expunge = true)`: Moves the message to the specified folder.
 - `delete(bool $expunge = true)`: Marks the message as deleted and, if desired, expunges it from the folder.
 
-##### Parsing and String Conversion
+#### Parsing and String Conversion
 
 - `parse()`: Parses the raw message data into a `MailMimeMessage` instance for deeper inspection (e.g., extracting structured content, attachments, etc.).
   > **Note:** An exception is thrown if both headers and contents are empty.
 - `__toString()`: Converts the message back to its full raw string (headers and contents combined), which is useful for logging or re-sending the email.
