New Product Alerts Question

Hello, I am curious if anyone knows of a good plugin that will achieve what I am wanting.

I have a Woo Commerce website for book reviews. People who are members of my site can download the book and review it for free. The books are submitted by the authors.

My users would love a feature where they can get an email notification when there is a new book in the genre (product category) that they enjoy.

How can I do this? I see a lot of plugins for low stock which doesn’t really apply. I just need something that will automatically send them an email notification when a book in their chosen genre is uploaded. I don’t have time to manage this manually.
