Keeping multiple spaces between words

In the emails we send out using zendesk, we have content that require us to maintain the extra spaces between words.

e.g. "A B   C"

(3 spaces between B and C)

However, the content appears as "A B C" with 2 spaces between B and C removed.

How can we maintain the spaces?

I have tried using css "white-space:pre" and replacing spaces to   but they get rendered as text.
