Thank you Vero. I hadn't explored workflows — Wow, I can now see their potential. I got it working with your guidance. Thanks again.

@caspian An alternative way to do this is with an extremely simple workflow connecting a Keyword object to an Launch Apps/Files;
 
You can then set your keyword to the word you want, with "no argument" on the right, and drag the Spark app to the "Launch Apps" object.
 
Finally, you can hide Mail.app from your results by dragging it to Spotlight's Privacy tab, then typing "reload" into Alfred to refresh the application cache. You'll never accidentally launch Mail again
 
Cheers,
Vero
