Outbound - A single events API for emails, push, sms, and voice
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. They'll be able to use trusted providers like sendgrid, twilio and apple so you don't have to worry about message delivery.

In plain words
Outbound is a unified messaging platform that lets product managers create and trigger customer communications across email, SMS, push notifications, and voice without developer involvement. It integrates with established providers like SendGrid, Twilio, and Apple to handle message delivery. The service is designed for teams who want to separate messaging logic from product development, allowing engineers to focus on core features while non-technical stakeholders manage user-facing messages and their delivery channels.

inbound 2025 · inbound.new · ▲227Hey 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…

SuprSend2022 · suprsend.com · ▲406We as developers, build and maintain many services in code, one of them being notification service. In the last 5-7 years, API-to-user communications have exploded across SMS, email, chat apps, mobile, and web push. As a consequence, notification service handling them has become quite complex. Developers spend time building integrations with multiple providers, create templates for each channel, managing scheduling and routing based on preferences, maintaining queues to deliver notifications on time while managing scale. Besides, product teams have poor visibility on notifications as…

Talanoa▲346Hi 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…
