If you set the Section Break between the envelope and the first page to
Hidden (and don't print hidden text) then you won't get the blank page
printed.

View All (the pilcrow icon on the toolbar)
Select the "=== Section Break (Next Line) ===" (at the top of the envelope)
Select Format Font from the Menu
Check Hidden

I am trying to create an envelope template that I can store in my templates.
Every time I create a new template I only get an option to print or add to
document which forces me to print a blank page every time. I just want an
envelope without the letter portion of the document.
