Show HN: I built a Personalized Newsletter Feed- Emails you curated substacks (newsletterguide.vercel.app)

Hi. a problem i found is that it is very hard to find substack newsletters, so I built a way to find substacks that you might be into, and it emails you a curated email that contains a list of substacks that you might be interested in. Note that the data in this is dummy data, the subscription thing is a placeholder and I haven't set up the submit your substack function yet
