As some others have mentioned, the best channel is the one that you put effort into and are able to make work for you. You won't know which one that is until you've made your best guess on where to start, put together a plan, and executed on that plan for some period of time in order to measure your results and have data to inform how to proceed from there.

With that said, my recommendation on the channel to pursue first given your market would be Instagram, and Facebook as a secondary.

At LemonStand, we work with many subscription box companies, and women-centric boxes tend to do really well with a well executed Instagram marketing plan.

Usually, they follow a three-fold approach: 1) Deploy a quality organic content strategy. Quality imagery, with quality hashtags and captions. 2) Supplement with paid posts. Start small, experiment and measure results + iterate. 3) Work with influencers. You can use one of the many influencer marketing platforms to get matched up with an influencer, or find influencers yourself and reach out to them.

Another channel worth exploring is working with bloggers who already write about topics related to your box. Often times you can find box reviewers who will write a review if you send them a box for free. I've seen this approach have very positive results, and often goes hand-in-hand with Instagram marketing.

There's an article published recently on our blog that covers some tips on Instagram marketing for eCommerce brands. Check it out: https://blog.lemonstand.com/marketing-tips-instagram-for-ecommerce/
