Your Top 3 Sources of Trafffic? (Google)

I didn't go into enough detail. Basically what I was trying to say was that if you pay $.50 per click and you only get an immediate $.30 back per click from some of them buying a OTO for example then it doesn't end there and you have to factor in what your average customer is worth to your business over months or years, not just what they are worth on the front end.

Assuming you have a solid funnel, give value often, and pitch great products that will help your customers then you can expect to make around $1 per subscriber per month. So that $.30 EPC that you were making on the front end is actually around $10 to $12 a year down the road therefore taking your $.50 clicks from a small immediate loss to a large ROI as the months go by since you can remarket over and over again to the same customers.

And as far as making an average of $1.50 per subscriber the next month that was just an example of what could happen if you pitched a great offer that converts well. I prefer not to say exact figures so those are just examples. There are way too many variables involved in email marketing to making exact calculations.

If you want to maximize your ROI though with your list then start sending them emails, giving them real value that gets them results and then occasionally pitch them products that relate to what you have been teaching them.

You will be building your trust and credibility and your customers will love you for it and want to return the favor. Just treat your customers like gold. That alone goes a long way.
