Subject line: Preview of ACM TOC

Hi [FIRSTNAME],

Really short email for you today!

I bet you're thinking… what the heck is ACM TOC?

Well it stands for Adwords Cash Mountain Table Of Contents. 
;)

Just thought I would remind you to look over the table of 
contents at:

[Your Sales Page Link]

…so that you could get a better idea of what you can expect 
to learn while you're reading your copy of ACM.

Talk soon,

[YOURNAME]

PS - Look for an email soon with *Last Chance!  Adwords Cash 
Mountain* in the subject line
