    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…

    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'm the founder of AhaSend. We've built a transactional email service specifically for developers, with a Pay-As-You-Go pricing model ($0.50 per 1,000 emails) and up to 70% volume discount for platform partners. While there are many ESPs out there, we focused heavily on the Developer Experience to solve the pain of building and testing email flows: * The CLI: Heavily inspired by the Stripe CLI, we built a tool that lets you develop and debug locally.

    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
