InboxGreen

What it does

Most senders don't know their SPF, DKIM or DMARC is broken until emails start bouncing or landing in spam. InboxGreen checks your domain's DNS records in seconds, no login needed. See what is passing, failing, or missing. The FixKit generates ready-to-paste DNS records for Cloudflare, Namecheap, Google Workspace and Microsoft 365. Includes 28 free DNS tools: blacklist checker, DKIM finder, SPF tester, DMARC analyzer, and more.

We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
