HTML Editor in Newsletter Remove some style elements when saving it

I am sending my first newsletter email from ERPNext V14.11. I wrote the email using Visual Studio code, and when I copied the code and pasted it into the HTML Editor, just when I hit Save, the editor removed the style of my table data.

Thanks a lot

Hi @mr-elamin,

You can apply custom styles to elements by using a style tag and adding CSS based on the class or ID of the element.

Thank you very much for the tip.
it has worked when the email gets delivered!
