Miss Blue review

Miss Blue gives your business a virtual iMessage line and then gives you two ways to work it: an API for building sending and replies into your own product, and a Message Center — a shared team inbox — for people who will never touch code. It also offers CRM workflows and AI agents with human handoff, which puts it closer to a complete platform than to a bare sending endpoint.

What it is good at

• +Covers both audiences — an API for developers, a no-code inbox for your front desk.
• +CRM workflow and AI-agent features aim at sales follow-up, not just notifications.
• +A dedicated blue line keeps business threads separate from anyone's personal number.
• +Human handoff on the agent side is the right default for a channel customers reply to.

Where it will bite you

• −A broader platform means more surface area to evaluate than a pure sending API.
• −Several protocol-level capabilities are not stated plainly on the marketing site — confirm the ones you depend on.
• −Published response-rate and revenue figures are the vendor's own; treat them as claims.

What Miss Blue claims

Reported as the vendor's own marketing claims. We have not independently reproduced these numbers, and neither should you treat them as benchmarks.

• “80% higher response rates than SMS outreach
• “37% more attributed revenue than SMS outreach

The shape of the API

Illustrative — parameter names and endpoints change. Treat this as the flavour of the integration, and copy the real thing from the official docs.

const res = await fetch("https://api.missblue.dev/v1/messages", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.MISSBLUE_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    to: "+15551234567",
    text: "Your invoice is ready: " + tagged("https://acme.co/inv/8821", {
      campaign: "invoice_ready",
    }),
  }),
});
 
if (!res.ok) throw new Error(`send failed: ${res.status}`);
