Your whole email stack, run by agents you control.
Koltrix is a team inbox on your own domain, an email API for your product, and AI agents with inboxes of their own. You choose what each agent may do: draft, ask first, or reply when it is sure. Works with Claude and ChatGPT. 7-day trial, no card.
Hi Product Hunt, I’m Venkat, the solo founder of Koltrix.
I built Koltrix because email for a small team ends up split across a shared inbox tool, a sending service and a pile of DNS records. Koltrix puts them in one place: a team inbox on your own domain, an email API and SMTP relay for your product, and SPF, DKIM and DMARC set up and checked for you.
The part I’m most curious to hear about is the AI side. You can connect Claude, ChatGPT or Cursor to your inbox, and by default nothing is sent without your yes.
There’s a 7-day free trial with no card, and your domain is set up in about 10 minutes. I’m here all day. Ask me anything, and tell me what’s missing. https://koltrix.com/
