  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…

  Talanoa▲340

  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…

  JS library to make your website instant▲426

  http://instantclick.io/ It seems the internet architecture won't bring us instant websites anytime soon. So here is a hack. I released this JS library last month (today is version 2.0 release, fixing v1.0's rough edges), it makes use of HTML5's pushState and preloading to make a website instant. It works like this: before clicking on a link, you'll hover over it. And there's a delay of 200-300 ms between these two events. InstantClick uses this delay to preload a page, when you click on a link it will display instantly in most case. (You can test on the website.) That's…

  For a while, I had this idea of redesigning Microsoft employee badges for a modern and neat look. So I spared a few hours this weekend. It’s over a year Microsoft has started to rebrand itself, starting from its logo to a brand new looking OS, from campus shuttles to direction signs on the cam
