InboxJoy - Stupidly Simple Cold Outreach

Connect unlimited domains and inboxes. InboxJoy rotates sending across them automatically and watches bounce rates — if an inbox starts bouncing, it stops sending from it before your domain gets burned. Connect Gmail or Outlook in one click. Upload a CSV. No dedicated domains, no DNS, no ops layer. Also works entirely from Claude/ChatGPT via MCP. $25/mo flat, unlimited access. 7-day free trial.

Hey PH 👋 InboxJoy is stupidly simple on purpose. Every outreach tool I tried assumed I had a sales-ops person. I don't. Most of you don't either. So: Gmail/Outlook in, CSV in, AI drafts the steps, press go. Warm-up ramps, send caps, and reply detection all run automatically — it stops emailing anyone who replies. First campaign live in ~10 minutes. Bonus: it's an MCP server, so you can run your whole outbound from Claude. AMA!

 How does the automatic inbox rotation actually decide when to switch ?
