Back in 2010 I had an idea for a service that would allow people to easily create semi-permanent email aliases so that they could give an email address to people and websites without revealing their real email address. These aliases will continue to work indefinitely unless you choose to block them. My brother and I spent a few months building the initial version and launched the website in July 2010. For the first year we had about 50 signups per month, by 2013 this had increased to 1500 and it's currently around 3500 per month. Similarly, our revenue grew consistently but slowly - doubling…

Introducing Posthorn, a self hosted email gateway. One docker container (or Go binary) between every self hosted app on your VPS and your transactional email provider. Set up Posthorn once, point your apps to it, done. I was trying to deploy Ghost on a DigitalOcean droplet and found that DO and many different VPS services have started to block the default SMTP ports to try to combat the various types of abuse they get. To actually configure my app, I had to hack together a Postfix relay. In another project, I had a static site which had a contact form, but my free Formspree account was…

Heimdall▲126Hey HN, We built Heimdall (heimdallspace.com) because the existing tools for space situational awareness are genuinely painful to use: clunky interfaces, fragmented data sources, slow rendering. The ones that aren't are locked behind enterprise solutions. We thought the foundation of this should be open and accessible. The goal is a satellite observability platform: one place that gives operators complete, real-time insight into their assets and the orbital environment around them. Today's release is the foundation—aggregating and rendering the full public space catalog (30,000+ objects) in…

HappyMail▲201Eight years ago, I was job hunting and felt embarrassed by my Gmail address. I tried registering firstname.lastname — taken everywhere. So I thought: "I'm in IT, I'll set up my own domain with my own IMAP/SMTP. How hard could it be?" A lot went wrong. Forgotten renewals. rocky DNS mistakes. I ended migrating toward Google Workspace, but in the end it felt overkill, having a subscription there plus the whole registrar subscription, and the whole GAFAM sticker on it. Moreover, the final price was way too high for me at the time. Six months ago, someone approached me and related to that…

Hey guys, so I've been building my own Gmail for the past few weeks and would like your feedback. Find a preview here: http://i.imgur.com/UDz2y.png (Mouse cursor is over the "REPLY" button, to show the hover-effect) The app you see in the screenshot is what I've been using in the past week and it starts to feel better than the gmail interface. Just a quick explanation: - It's conversation-based like Gmail. - Conversations with new emails are on the left. - Conversations may be labeled ... based on predefined filters or manually. - Every conversation stays in the left sidebar until marked…
