I built a cold email tool that scores reply probability before you send – launching on PH today

Most cold email tools optimize for generation speed. I optimized for one thing only: reply rate.
After sending hundreds of outreach emails, I noticed the same pattern: structure and timing mattered more than the offer itself.
So I built ReplyAI around 33 reply-focused rules. Before generating, it analyzes your niche and identifies the exact pain point. After generating, it scores the email on reply likelihood.
Free tier: 5 emails/day, no signup needed.

Would love brutal feedback from this community — what would make you actually use this?
