Show HN: Hello Inbox – Maximize inbox placement for email marketing campaigns
Hello Inbox is an email deliverability SaaS that uses a RAG system trained on years of specialist knowledge and real-world cases to help businesses improve their email campaign inbox placement rates. The tool aims to solve common deliverability frustrations.
Background
- Hello Inbox is a SaaS tool that helps email marketers improve "deliverability" — the chance their emails land in recipients' main inbox instead of the spam folder or being blocked entirely.
- It uses a RAG (Retrieval-Augmented Generation) system, meaning it combines a knowledge base of real-world cases with an AI model to give tailored advice, rather than just generic tips.
- The founder is an independent specialist from Upwork (a freelancing platform), packaging 4+ years of hands-on deliverability experience into automated software.
- This matters because email marketing ROI depends entirely on inbox placement; spam filters have grown stricter with algorithms like Gmail's, and many small businesses lack the expertise to navigate authentication protocols (SPF, DKIM, DMARC), IP reputation, and content scoring.
- The post is a "Show HN" — a category on Hacker News where makers present their projects for community feedback, not a press release or ad.
