Cheap/Starter Newsletter Solution

What I needed was an inexpensive way to test if newsletters would benefit my ecom site, and options were thin, but this has ended up doing exactly as i’d hoped so far. Limiting how many it sends per hour so as not to exceed hosting quotas is the key, allowing both a gutenberg style editor *and* classic HTML/CSS editor is great. I ended up just using an LLM to design the code.
