I made an open source Mailchimp RSS-to-Email alternative
Hi all! Excited to share rss2newsletter after completing dev work for the initial release. The idea for this project came out of necessity, as I wanted to share my articles via email newsletter. I was looking for a super minimal, lightweight, and open source solution, and when none existed, I decided to create one. For any sizable number of email recipients, a popular platform like Mailchimp will easily cost you hundreds or even thousands per month in per-contact fees. rss2newsletter, on the other hand, allows you to use Amazon SES, so you can reach your audience at pennies on the dollar.…
In plain words
rss2newsletter is an open source tool that converts RSS feeds into automated email newsletters. It's designed for content creators and publishers who want a lightweight alternative to commercial services like Mailchimp. The software uses Amazon SES for email delivery, significantly reducing costs for reaching large audiences. It runs with minimal system resources and requires no ongoing maintenance once configured, making it accessible for individual bloggers and small publications.

Hi all! Excited to share rss2newsletter after completing dev work for the initial release. The idea for this project came out of necessity, as I wanted to share my articles via email newsletter. I was looking for a super minimal, lightweight, and open source solution, and when none existed, I decided to create one. For any sizable number of email recipients, a popular platform like Mailchimp will easily cost you hundreds or even thousands per month in per-contact fees. rss2newsletter, on the other hand, allows you to use Amazon SES, so you can reach your audience at pennies on the dollar. Beyond these factors, I also wanted something that could run on an internet-connected potato it's so easy on your system and fully automated so you can set it and forget it. So, I created (and put under a free software license): https://github.com/ElliotKillick/rss2newsletter rss2newsletter (integrating with Listmonk and Amazon SES for ultra-low-cost emails) is a drop-in solution that requires almost no setup besides connecting with SES and styling your emails. It's also competitive at what it does with proprietary self-hosted solutions like Sendy, which requires your system/VPS to have some rather beefy specs to run well. Let me know if there are any other features you would like to see. I hope you can find my project helpful to you!

Many years ago, I made VJ softwares (to mix live visuals in clubs) for unexpected platforms like the Game Boy Advance, the Playstation 2 and the Raspberry Pi. This year, I’m back with a new web-app: Pikimov. Inspired by Photopea (a free Photoshop clone), I created this web-based motion design & video editor as an alternative to After Effects, to fill empty void. It's free, without signup, without cloud uploads (your files stay on your machine), and your projects are not used for AI models training.
