Hi all! Excited to share cc.dev after months of work and refinement. The idea for this product came from trying to do email marketing for my side project, CubeDesk, a site where Rubik's Cube enthusiasts can time themselves, race with one another, train algorithms — it's a fun niche! With over 40k users, sending even a single campaign was becoming expensive with MailChimp. I knew AWS SES would be much cheaper, but it’s just an API with none of the other necessities you need for a robust email marketing platform. Beyond cost, I was also frustrated with having to make sure my database was…

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.…

We've tried systems like OSTicket, OTRS etc, but never found anything to our liking. Most systems were cluttered, slow or too advanced. Brimir is simple but usefull.

Hey HN, Chandler from Dittofeed (https://github.com/dittofeed/dittofeed). We just added low-code functionality to our open-source email template editor. The editor features a Notion-inspired “/” command interface for inserting new blocks. You still have the option of using MJML or HTML, but we wanted to give everyone an easier option for creating primarily text-based emails. We have a live demo of the editor which you can access here (just hit the “Create Template” button): https://demo.dittofeed.com/dashboard/templates Since this is the first…
