This is what I am using to send my weekly notes on Ai, PR, and Digital Strategy from Hugo. It can work from any rss feed.
You can pass the email addresses as a CSV, and it supports templates.
My production version uses Node-RED to setup a subscription_manager server with API endpoints. I’ve added the exported json file of the flow that handles that logic.
There is even an unsubscribe link for each sent email, but that won’t work if you’re using the CSV method.
This is how it looks for the user: Weekly Notes | Short review of the week, useful links, random thoughts
It’s also a much better solution than using tinyletter like I posted some time ago. Creating a simple newsletter for hugo
