Phone Numbers for AI Agents
AgentPhone gives AI agents their own phone number. One API call provisions a number, and a single unified webhook handles both voice calls and text messages in the same format. Agents reply with text and AgentPhone handles the speech layer, so an autonomous agent can call, text, and act without a human in the loop.
It ships with Python and Node SDKs, a REST API, and a native MCP server that works with Claude Code, Cursor, and any MCP client, all documented in the AgentPhone docs. Their customers build receptionists, AI workers, on-call engineering flows, sales and lead-follow-up agents, coding agents, and verification inboxes for autonomous agents. The common thread: give an agent a real phone identity so it can hold a genuine conversation on the channels people actually use.
For messaging to feel real, an agent's texts can't arrive as a generic green bubble. They need to land as native iMessage, with the blue bubble, delivered receipt, and typing indicator people trust, and they need to thread correctly and deliver reliably at high volume. That iMessage layer is what AgentPhone partnered with Blooio's iMessage API to run.
The Challenge
Agents send and receive at machine speed: bidirectional, high-frequency, and bursty. AgentPhone needed an iMessage layer that could keep up without dropping a message mid-conversation, and that made every agent's number feel like a real person's.
- Native iMessage delivery, with the blue bubble, delivered receipt, and typing indicator that recipients trust.
- A dedicated, reputable phone number per agent, provisioned instantly and managed over time.
- Real delivery telemetry, not just a “sent” status, so AgentPhone knows every message actually landed.
- Headroom to absorb sudden spikes as individual agents go from a handful of messages to tens of thousands.
Why Blooio: The Partnership
AgentPhone and Blooio partnered to put a real, deliverable phone identity behind every agent. Blooio provisions dedicated iMessage-capable numbers, real-time inbound webhooks, and full delivery-lifecycle tracking, all behind one API. AgentPhone builds the agent experience and the voice layer; Blooio delivers the iMessages and proves it.
Dedicated numbers per agent
Every agent gets its own real, reputable phone number, provisioned and rotated transparently by Blooio.
Native iMessage delivery
Messages land as real iMessage, with a blue bubble, delivered receipt, and typing indicator, so an agent reads like a person.
Real-time webhooks
Sub-second inbound delivery means an agent can respond the instant someone replies.
Full lifecycle tracking
Every message is tracked from queued → sent → delivered → read, surfaced through the API.
Our whole focus is giving AI agents a phone number and making that effortless. We started out building the messaging layer ourselves, but we'd rather partner with a team that has real expertise here. Blooio gives our customers reliable infrastructure, so we can focus on delivering every channel they want.
The Results
AgentPhone has processed more than 340,000 messages through Blooio at a 98.07% delivery rate across the entire volume, reaching over 26,000 unique recipients. At peak, a single month carried more than 130,000 messages, all absorbed with zero infrastructure changes on AgentPhone's side.
And these are real conversations, not one-way blasts: nearly half of the people an agent reaches reply back. That's the difference native iMessage makes: a number people actually answer.

Blooio Powers the Agent-Messaging Category
AgentPhone isn't the only company Blooio powers. Blooio is the iMessage backbone for several resellers and platforms like AgentPhone, who build their own products on top of our infrastructure and resell it to their customers. A number of them run completely white-labeled, so their end customers never see Blooio at all.
Tailored is another provider built on Blooio, a booking platform that delivered 45K+ messages at 97.5% delivery. And Aneu's Social AI lives inside people's texts on the same infrastructure. Whether you're handing phone numbers to AI agents or to service businesses, Blooio is the layer that makes the messages land.

The next wave of software won't just live in a browser tab; it'll pick up the phone. As agents move from answering questions to taking actions on your behalf, whether that's booking the table, following up the lead, or calling you back, they need a real, persistent phone identity that people trust.
AgentPhone is building that future, and Blooio is the infrastructure that makes an agent's number indistinguishable from a person's: real iMessage, real delivery, real conversations. If you're building an AI agent on iMessage, Blooio scales underneath you. AgentPhone builds the agent. Blooio delivers the messages.
