I Recently Bought OA Lead List – I Have a Question?

I spent most of my time sourcing products, which I why I decided to buy OA lead lists. I thought that I would save time to focus on other aspects of my Amazon business. I didn’t want to go through the hassle of hiring VAs, training them, and managing them every day, which is why I purchased an OA lead list.

Although the leads they provided were 80% good, I’m confused is this the right way of doing things and can I grow my business with OA lead lists in the long term?
