I started dropshipping on eBay a bit under a year ago and the business has been growing nicely. Making around 50 sales a day on eBay I now have built a list of few thousand PayPal emails from my customers that have purchased stuff from me. This list will grow exponentially as I scale up the business. How could I monetise these emails? I know it's not the best obviously as they are not very targeted (just by country) but afterall these are people capable of making PayPal payments and at least country-targeted. In any case, bit of a shotgun approach. Any ideas what I could do? So far I have thought about spamming them with CPA offers that attract wide audiences, e.g. pin submits for contests or similar, or Clickbank offers. Alternatively, I could use it to promote some affiliate site but as I'm concentrating most of my time on the actual dropshipping, I'm hoping to find some easy way how to make a bit of extra with the emails. What would you recommend?
