# Leadterra: Agent-Ready Outbound Email APIs for GTM

> Leadterra gives your agents and GTM workflows programmatic control over outbound email — campaigns, sender pools, leads, and reply intelligence.

Leadterra is a private outbound email infrastructure built for GTM teams and AI agents. With a handful of API calls, you can spin up campaigns, route sends through private sender pools, enroll leads, and pull classified replies back into your workflows — all without touching a dashboard.

## Get up and running

<Steps>
  <Step title="Get an API key">
    Log in to [app.leadterra.co](https://app.leadterra.co), navigate to **Settings → API Keys**, and create a new key. Your key will look like `sk_live_YOUR_KEY`.
  </Step>

  <Step title="Inspect your sender pool">
    Call `GET /v1/sender-pools` to see your available delivery capacity and daily send volume before you launch any campaigns.
  </Step>

  <Step title="Create a campaign">
    Call `POST /v1/campaigns` with a name and at least one sequence step. Leadterra creates the campaign in draft state so you can review it before sending.
  </Step>

  <Step title="Enroll leads and start">
    Push your leads with `POST /v1/campaigns/:id/leads/bulk`, then fire `POST /v1/campaigns/:id/start` to begin queueing the first sequence step.
  </Step>
