LinkedInbox

Know which LinkedIn messages actually work.

2 followers

Most LinkedIn outreach tools focus on sending more messages or automating workflows. After years of doing LinkedIn cold outreach myself, that never solved my real problem: I didn’t know which messages worked, which offers resonated, or if people even wanted what I was building. LinkedInbox focuses on understanding what’s actually working by analyzing past LinkedIn conversations, clustering templates with AI, and surfacing which openers create real interest.

Hey Product Hunters 👋 I’m Valentin, the maker of LinkedInbox. I spent about 2 years doing LinkedIn cold outreach in hospitality for a previous launch. The process always felt the same: send messages, get ghosted, a few replies here and there but no real clarity. Even when people replied, I didn’t know why. Which opener worked? Which angle resonated? Or if people even wanted what I was building at all. I tried automation tools, but they felt too artificial and didn’t help me learn from my past conversations. They helped me send more messages, not understand them. That’s why I built LinkedInbox. Instead of focusing on volume, it looks at your existing LinkedIn DMs. You can import your conversations, let AI cluster your message templates, and see which openers and angles actually generate interest so you know what to double down on and what to stop sending. Happy to answer questions, get feedback, or hear how others here think about measuring outreach effectiveness 🙏
