Ask HN: I've great content but don't know how to bring subscribers

I've been working on my newsletter website project from last one month. Got decent web design and hired a freelancers to have a good content. But no idea How I am going to increase the traffic and subscribers to this site https://www.makemint.co/

Let me know if you guys know any white hat way. I thought bring traffic through Google webstories and it's not working out for me. No use of it.
