Simple email subscribe form

As highlighted here I want to, ideally, use Obsidian to produce an email newsletter, in which case, then be able to have a simple subscribe form without adding in a third-part tool (of which there are many, some free on limited basis, until you grow then it gets expensive).

Anyway, simple email capture form. That’s it.

I can’t code, so just posting in case anyone wants to have a crack at it.
