How to restrict copy of text of the mail

There are several ways to restrict copying of text from an email:

Use a watermark: You can add a watermark to the text in your email that makes it difficult to copy. This can be a faint image or text that is overlaid on top of the original text.
Use a font that is difficult to read: You can use a font that is difficult to read, such as a font with a low resolution or a font that is designed to be difficult to copy.
Use a background image: You can add a background image to the text in your email that makes it difficult to copy. This can be a faint image or a busy pattern that makes it hard to select the text.
Use a JavaScript-based solution: You can use JavaScript to detect when someone is trying to copy the text and prevent it from being copied. This can be done by adding a script to the email that checks for the ctrl+c or cmd+c keyboard shortcut and prevents it from being executed.
Use a PDF: You can convert your email to a PDF and send it as an attachment. This will make it difficult for someone to copy the text, as PDFs are not easily editable.
Use a secure email service: Some email services, such as ProtonMail, offer built-in protection against text copying.
Use a plugin: There are several plugins available that can help prevent text copying, such as the "Copy Protection" plugin for Gmail.

Here is an example of how you can use JavaScript to prevent text copying:

<script>
  document.addEventListener("copy", function(event) {
    event.preventDefault();
  });
</script>

This code adds an event listener to the copy event, which is triggered when someone tries to copy text. The preventDefault() method is then called to prevent the text from being copied.

It's worth noting that while these methods can make it more difficult for someone to copy the text, they are not foolproof and can be bypassed by determined individuals.
