Best Markeing Technique for Internation Customer Base

Please suggest few good marketing techniques for a product which is targetted over an internation customer base.
Tele Marketing is not possible and Email Marketing is not giving good results.

 

I would go with direct advertising, if you can. Do you know where you potential customer base is lurking? Is there a popular forum out there in your niche? Consider advertising on sites related to your business.

Also, for international purposes, PPC might be a good option for you. It would be good for advertising to people outside of the United States. I hear it is far cheaper when setup properly and you know then that you will be getting a good ROI assuming everything else is okay.
