24 alternatives to Open source mobile email client built with HTML/CSS/JS
Hey HN, I've been working on an email client and wanted to get some feedback! Minimail is built on Phonegap, so it uses HTML/CSS/JS for everything user-facing. The app also uses emailbox (a related project of mine) as the backend API for receiving/parsing/sending emails. I think email clients need a huge UX/UI overhaul, and so I'm trying to build a flexible/hackable email client that anyone can customize to fit their email workflow. Thanks for any feedback!

It has: - Everything for creating, managing and delivering SaaS emails in one platform, - Easy-to-use email API for sending password resets, receipts, etc. - Messenger for writing product updates and newsletters, - Email automations for onboarding and lifecycle flows, - Fast email…

I’m thrilled to finally be able to show everyone what we’ve been working on for the last 2 years. We’re re-inventing the email experience to help you email smarter and faster, so you can get more done, and maybe even actually enjoy your inbox. When we launched Firebase here 10 years ago, HN was tough but fair, and I expect no less this time around! I hope you’ll check out what we’ve built and share your feedback. I’ll be around here all day and am happy to answer any questions. Let us know what you think!

I've been frustrated one too many times by terrible airplane wifi and not being able to load Gmail or Superhuman when all I want to do is get a few simple text-only emails out the door. These clients have become pretty bloated with the assumption you've always got great bandwidth. So I vibe coded BAREMAIL. It's open source, has no backend, and you can just set it up for yourself. Takes ~3 mins to setup API access via Google Cloud Platform (thanks for making this not super easy Google!) I tried to maintain nice design and some important keyboard shortcuts without getting to overBEARing.

Zero▲845Hi HN, I’m Nizar, and I’m building Zero (https://0.email) — an AI-powered email client that manages your inbox for you. Email hasn’t changed in decades, even though the way we work has. The average knowledge worker now spends close to 30% of their week on email, constantly reacting, replying, and sorting through noise. It’s become one of the biggest productivity sinks in modern work. At the same time, AI has transformed how we write, plan, and collaborate — yet our inboxes are still stuck in the past. I built Zero to fix that. Zero automatically prioritizes, organizes, and even…

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 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…

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…
