looking for blog Subscribe plugin which isn't a sidebar widged

Hello, I’m looking for a blog subscribe blog plugin which doesn’t show up in the sidebar. But which I can add in a “page”.
I’ve looked though the plugins but I only get sidebar plugins or plugins which you have to pay or to give way to much of your own details for such as homemailaddress.

So I wonder if there is any solution.
Because I got a customer who want the subscribe form in the sidebar widget area.
But she want it like this: https://themccordlist.com/showroom-magazine-sign-up/ no matter what..

so I wonder if anybody can help.. without I need to use a plugin who ask lots of my identity…
