There is not one easy answer to that question. You need to have a strategy in place and test every traffic source.
Before you start testing, you need to ensure your landing page is correctly optimise to convert traffic into sales of opt-ins or you may be wasting money.
Low risk is growing your website rankings via SEO and instagram following. The only real investment with that strategy is time.
Otherwise, you can test google search, bing, facebook, youtube, pinterest etc. Be mindful that you need to abide by all their terms & conditions prior to advertising or your ad account may get disabled.
You can also purchase solo ads which can work well too.
