Best way to display newsletter (CMS) on website?

I know there are quite a few posts on here about integrating CMS but I’m looking for a straight-forward response. Best way to display a newsletter on a Webflow website? What is the best program to use and how to integrate it? Can it be done with Webflow’s hosting?

I will be building a website for a daycare center and they would like a newsletter they can easily update.

Thanks!
