Is there a way to use formulas in Email templates to handle conditional formatting?

For example, I'd like to use the formula UPPER( NAME HERE ) to cause the person's name to appear in all CAPS, even though it may appear as "Name Here" in the SFDC database. This is just one example.

Furthermore, there may be conditions upon which you do or do not want to show certain information in an email response. Using formulas would be helpful. I didn't see any documentation on this when search for "formulas in email templates" -- so I'm not sure if it's possible.

Thanks.
