How do I find great influencers/reviewers?

I have a book coming out next week, and I’m still looking for more influencers to send to my publisher. The book is Christian non-fiction, great for women ages 30-60(ish) who are worn out from legalism, and buried in spiritual guilt (like mom guilt, but holier :-) ). How do I find people to send this to? Any special hashtag list to research? Do I just DM anyone who might be interested? What should I look for on social sites? Any advice would be greatly appreciated!
