OutboundOS

What it does

OutboundOS is a complete outbound email system built around infrastructure you already control. Connect your own SMTP, import contacts, build branching email journeys, personalise messages with AI, schedule follow-ups, manage clients in separate workspaces, collaborate with your team and track results. No sending credits. No per-email pricing. No monthly subscription. Your SMTP. Your contacts. Your outbound system.

Build branching email journeys across dedicated workspaces with their own contacts, templates, and analytics. Send through your own SMTP with one-time lifetime pricing.

Every client gets their own workspace: separate contacts, journeys, templates, analytics and SMTP. You plug in your own mail server, so nobody meters your sends and nobody prices your growth. That is why OutboundOS costs once. No implementation call, no onboarding fee, no sales demo. Sign up and build. One per client, brand or region. Everything inside stays scoped to it, with no crossover. Zoho, Google Workspace, Mailgun, Amazon SES. Verify the handshake in app before a single email leaves. CSV import, templates, delays, exact send times and separate follow ups for openers and non openers. Per workspace analytics and logs show exactly how many contacts sit in each step, and why.

  Hey HN! I've been working on Inbound (inbound.new) - an email system that lets you programmatically manage email addresses and route them to AI agents, webhooks, or forward them anywhere. The core idea: instead of manually managing email addresses, you create them on-demand via API and route incoming emails to your AI agents or other automated systems. For AI Agents: Create [email protected] and emails get sent to your AI agent as webhooks. Your agent can reply using our SDK. Perfect for AI customer support or automated responses. For Email Forwarding: Set up [email protected] to…

  Empower your product manager. Let them decide what the messages to your users say, when those messages are triggered, as well as how they are sent (sms, email, etc.) while you focus on building product features.

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
