Open sourcing my email sending startup

In plain words

Maildown is an open-source command-line tool that simplifies sending transactional emails by wrapping Amazon SES with built-in Markdown and styling support. Designed for developers integrating email functionality into projects, it reduces the complexity of setting up transactional mail systems. The tool was released as open source after the creator decided to pivot away from pursuing it as a commercial startup.

  Maildown – Markdown email campaigns2019 · ▲92

  Hi, The beta program of my new startup, Maildown, is now complete and is now accepting paying customers: https://www.maildown.app As well as a lot of stability enhancements, we've added a new help system, a new CLI (https://github.com/chris104957/mailer-cli) and a REST API. Maildown lets you create transactional and marketing email campaigns using Markdown syntax, so you can generate and send your email content far more quickly than with traditional WYSIWYG editors. Thanks for looking, Chris

  I made a MailChimp alternative that connects to your database2023 · cc.dev · ▲302

  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…

  I made an open source Mailchimp RSS-to-Email alternative2024 · github.com · ▲109

  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.…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
