Copy and paste formatting issues in text blocks

I draft content in Word and need to copy and paste it into the newsletter template to email. Even when I use Control + Shift + V, to paste to match destination formatting, I have some major issues. I lose paragrpah spacing. The bullets are messed up. I lose bold text. etcetera. How do I work around this so I don't have to reformat every single text box? Is there any way I can paste html into a text box? I don't see options that are working that I can try.
