Sendune – The Email Platform for Anyone Using AWS SES

In plain words

Sendune is an email platform designed for developers and companies using Amazon Web Services (AWS). It provides tools to build and send emails through AWS Simple Email Service (SES), offering an alternative to third-party email services. The platform includes an open-source HTML email designer and was developed from an internal tool created in 2014. It targets tech-based companies looking to leverage AWS infrastructure for email operations while maintaining cost efficiency and reliability.

In the maker’s words, at launch

Just over two months ago, we shared our open source HTML email designer here and it very quickly hit the front-page: https://news.ycombinator.com/item?id=41007403. Here's some backstory. The open source email designer was the foundation and core part of an internal tool we started way back in 2014 to…

  Sendune – open-source HTML email designer2024 · ▲429

  Demo: https://designer.sendune.com/ Code: https://github.com/SendWithSES/Drag-and-Drop-Email-Designer HTML for email is probably the hardest code to write. Even a teeny-tiny deviation from the rules will break the email in untold combination of os/desktop/mobile clients. It's mid 2024. Almost 50 years since email was invented and 35 years since HTML was born. A 'basic-open-source-HTML-email-designer' must be a solved problem, right? We thought so too. Sadly, that's not the case. There are a few decent open source email designers but they carry…

  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…

  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…
