The email management text area has Visual Editor and Text Editor. In Text Editor, you can use inline styles, add the style attribute to the relevant element. The style attribute can contain any CSS property. Also, you can use text mode and <br> tag for new line.

IMPORTANT: <br>  can be added only in Text mode. If switch to the Visual mode from text editor it is removed.
To avoid losing HTML code use text mode and <br class=””> tag for new line, <p class=””> for a new paragraph, <span class=””> for styling.
