How do you introduce a new feature to a customer?

How should I announce a new feature? The announcement should primarily be made over your blog, social media, and by sending emails to the existing customers and leads. After the release of the feature, you should set up tooltips and guides to let users know about the release inside your product.

Should I use modal or new page?

Modals are a good fit if your users often switch between products and the interactions are limited. New page is a good fit if the interactions are various and somewhat complex, but you do not ease switching to other projects.
