Free Email Infrastructure: How It Works

Shared‑Pool Inboxes with Real Reputation

KeyID allocates each agent a unique email address from a warm‑up pool of domains. These domains are pre‑warmed, rotated automatically when reputation degrades, and remain isolated per agent for inbound messages. Outbound reputation is managed at the pool level, ensuring that a single abusive agent cannot poison the entire system.

Zero‑Cost Provisioning

• No human setup or dashboard configuration required.
• No API keys—agents call POST https://keyid.ai/api/v1/provision directly.
• Supports Node.js, Python, and any REST‑compatible runtime.

Full Email Lifecycle Support

Agents can send, receive, and reply to messages, handle magic‑link verification, and store state for multi‑step workflows. This makes KeyID ideal for:

• Outbound outreach campaigns.
• Customer‑support bots that need persistent threads.
• Account registration flows that require email verification.

Free Phone Infrastructure: Real SMS & Voice Access

SMS‑Ready Phone Numbers

Each provisioned identity also receives a virtual phone number capable of receiving SMS and voice calls. The numbers are sourced from a shared pool that rotates to maintain carrier reputation, similar to the email pool.

Verification & OTP Handling

Agents can automatically capture one‑time passwords (OTPs), magic links, and TOTP codes sent via SMS, enabling seamless registration on platforms that enforce phone verification.

No Hidden Fees

Just like the email service, the phone service stays free up to 1,000 active identities. Scaling beyond that point requires a paid tier, but the free tier already covers most startup and SMB use‑cases.

Why AI Agents and Developers Should Care

Eliminate Mailbox‑Seat Economics

Traditional SaaS email providers charge per mailbox seat, which quickly becomes prohibitive for fleets of agents. KeyID’s model removes that cost barrier, allowing developers to focus on logic rather than licensing.

Zero‑Setup, Zero‑API‑Key Friction

Agents can provision identities on‑the‑fly without pre‑creating credentials. This is a game‑changer for dynamic environments like AI marketing agents that spin up per campaign.

Built‑In Abuse Protection

KeyID rate‑limits provisioning per IP and per identity. Abusive agents that trigger spam complaints are throttled or suspended automatically, preserving pool health for everyone.

Cross‑Platform Compatibility

KeyID integrates out‑of‑the‑box with popular AI runtimes:

• Claude, Cursor, and OpenAI CrewAI via the hosted MCP endpoint.
• LangChain, AutoGen, and Replit through the @keyid/sdk npm package.
• Playwright and n8n for web‑automation workflows.

Scalable Use Cases Powered by KeyID

Outreach Automation

Marketing teams can assign each campaign agent its own inbox and phone number, ensuring replies stay attached to the correct identity. This eliminates the “shared mailbox” nightmare and improves deliverability.

Virtual Assistants & Customer Support Bots

Support bots can handle ticket threads in real time, receive SMS alerts, and send follow‑up emails without human intervention. The AI marketing agents page showcases similar capabilities.

Research & Data Collection Agents

Agents that scrape websites, collect price data, or monitor competitor activity often need to pass email or phone verification. KeyID’s shared pool lets them do this at scale without manual captcha solving.

Onboarding & Marketplace Sellers

When launching a new SaaS marketplace, each seller can be provisioned a unique identity for registration, verification, and ongoing communication, reducing friction and support tickets.

For concrete examples of how AI‑driven workflows look in practice, explore UBOS’s UBOS templates for quick start. Templates like AI SEO Analyzer or AI Article Copywriter already embed email handling logic that can be swapped for KeyID identities.

How to Get Started with KeyID in Minutes

Step‑by‑Step Provisioning (No API Key)

// Node.js example
npm install @keyid/sdk
const { KeyID } = require('@keyid/sdk');
(async () => {
  const agent = new KeyID();
  const identity = await agent.provision(); // returns email & phone
  console.log(identity);
})();

# Python example
pip install keyid
from keyid import KeyID
agent = KeyID()
identity = agent.provision()
print(identity)

Both snippets hit POST https://keyid.ai/api/v1/provision directly, so there’s no need to store or rotate API credentials.

Integrate with Your Preferred MCP

KeyID’s hosted MCP endpoint (https://keyid.ai/mcp) can be added as a remote skill in Claude, Cursor, or any MCP‑compatible client. For example, in Claude you would add a “KeyID Identity” skill and call identity.provision() whenever a new bot instance launches.

Leverage UBOS Automation Studio

UBOS’s Workflow automation studio lets you chain the provisioning step with downstream actions like sending a welcome email, storing the identity in a database, or triggering a phone‑based OTP flow—all without writing custom glue code.

KeyID vs. Traditional Email/Phone Services

For developers who need to spin up hundreds of agents quickly, KeyID’s zero‑cost, zero‑setup model is a decisive advantage.

From Template to Production: A Quick Walkthrough

Suppose you want to launch an AI Video Generator that requires user verification via email and SMS. Using UBOS’s Web app editor on UBOS, you can:

1. Import the “AI Video Generator” template.
2. Add a “KeyID Identity” step from the UBOS partner program marketplace.
3. Configure the step to call agent.provision() and store the returned email/phone.
4. Use the stored credentials in the video generation workflow to send verification links and OTPs.

The result is a fully autonomous service that can onboard thousands of users without ever touching a human mailbox.
