Hey PH, I built an AI Mailer, not ordinary ->

I'm Kaustubh, the founder of CONCIEIT. I built Preacher because I was frustrated with cold email tools that send the same template to everyone and call it "personalisation."

The insight was simple: if I could read a company's website before emailing them, I'd write a much better email. So I built a tool that does exactly that, automatically, for every contact on my list.

A few things I'm proud of:

The self-serve model. You bring your own Groq/Open AI and smtp2go keys. Groq is free. smtp2go has a free tier. That means Preacher costs you nothing to start, your emails come from your real address, and we never touch your contacts. This felt like the right way to build it.

It's genuinely simple. Add API's → add upto 25 sender inboxes → upload CSV → write template → research → send. No workflows, no sequences, no CRM you have to learn. Just cold email that sounds like you wrote it.

The AI fills actual facts. Because it fetches the real company website, the paragraphs reference real things — their actual product, their actual market, their actual tone. Not "I noticed you're in the SaaS space."

Would love your feedback, especially on the onboarding flow and whether the key setup feels like too much friction. That's my biggest open question right now.
