Use this skill

Your agent runs on

Adds every file the skill has, pinned so you can update it. No account needed.

pip install "decimalai>=0.15"
decimalai skills add jeremylongshore-customerio-core-feature
claude --plugin-dir "$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.agents"

The same install from Python, for a notebook or a setup script.

Install

pip install "decimalai>=0.15"

Add the skill

from decimalai import skillpkg

# Writes .agents/skills and .decimal/skills.toml. Safe to run twice.
result = skillpkg.add("jeremylongshore-customerio-core-feature")
if result.exit_code:
    raise SystemExit(result.problems)

print("Added. Start Claude Code with the command below.")

Start Claude Code with it

claude --plugin-dir "$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.agents"

Type these in a Claude Code session. No account or API key. It writes the skill and any files it bundles, and asks first when its safety rating isn't Passed.

Add the DecimalAI plugin, once

/plugin marketplace add decimal-labs/decimalai-claude-plugins
/plugin install decimalai@decimalai

Install this skill

/decimalai:install jeremylongshore-customerio-core-feature

The plugin needs python3 and curl on your machine.

No Python or account. Claude Code picks it up in its next session.

Save it into your project

curl -fsSL --create-dirs -o .claude/skills/jeremylongshore-customerio-core-feature/SKILL.md https://app.decimal.ai/s/jeremylongshore-customerio-core-feature/SKILL.md

Copy SKILL.md

Save it in your project, as

Customer.io Core Features

Output

A scoped, consent-aware Customer.io feature configuration with a validated data contract and owner.
A test receipt showing intended audience, environment, event/message behavior, and safe rollback path.

Examples

Configure a feature in development with a synthetic profile and a narrowly defined event. Verify attributes, segment membership, and message preview before promotion. If the audience or consent behavior differs from expectation, disable the development configuration and correct the contract before proceeding.

Overview

Implement Customer.io's key platform features: transactional emails/push (password resets, receipts), API-triggered broadcasts (one-to-many on demand), segment-driving attributes, anonymous-to-known user merging, and person suppression/deletion.

Prerequisites

customerio-node installed
Track API credentials (CUSTOMERIO_SITE_ID + CUSTOMERIO_TRACK_API_KEY)
App API credential (CUSTOMERIO_APP_API_KEY) — required for transactional + broadcasts

Instructions

Feature 1: Transactional Email

Transactional messages are opt-in-implied messages (receipts, password resets). Create the template in Customer.io dashboard first, then call the API with data.

// lib/customerio-transactional.ts
import { APIClient, SendEmailRequest, RegionUS } from "customerio-node";

const api = new APIClient(process.env.CUSTOMERIO_APP_API_KEY!, {
  region: RegionUS,
});

// Send a transactional email
// transactional_message_id comes from the Customer.io dashboard template
async function sendPasswordReset(email: string, userId: string, resetUrl: string) {
  const request = new SendEmailRequest({
    to: email,
    transactional_message_id: "3",  // Template ID from dashboard
    message_data: {
      reset_url: resetUrl,
      expiry_hours: 24,
      support_email: "[email protected]",
    },
    identifiers: { id: userId },    // Links delivery metrics to user profile
  });

  const response = await api.sendEmail(request);
  // response = { delivery_id: "abc123", queued_at: 1704067200 }
  return response;
}

// Send an order confirmation with complex data
async function sendOrderConfirmation(
  email: string,
  userId: string,
  order: { id: string; items: { name: string; qty: number; price: number }[]; total: number }
) {
  const request = new SendEmailRequest({
    to: email,
    transactional_message_id: "5",
    message_data: {
      order_id: order.id,
      items: order.items,        // Accessible as {{ event.items }} in Liquid
      total: order.total,
      order_date: new Date().toISOString(),
    },
    identifiers: { id: userId },
  });

  return api.sendEmail(request);
}

Dashboard setup: Create transactional message at Transactional > Create Message. Use Liquid syntax: {{ data.reset_url }}, {{ data.order_id }}, {% for item in data.items %}.

Feature 2: Transactional Push

import { APIClient, SendPushRequest, RegionUS } from "customerio-node";

const api = new APIClient(process.env.CUSTOMERIO_APP_API_KEY!, {
  region: RegionUS,
});

async function sendPushNotification(userId: string, title: string, body: string) {
  const request = new SendPushRequest({
    transactional_message_id: "7",  // Push template ID
    identifiers: { id: userId },
    message_data: { title, body },
  });

  return api.sendPush(request);
}

Feature 3: API-Triggered Broadcasts

Broadcasts send to a pre-defined segment on demand. Define the segment and message in the dashboard, then trigger via API.

// lib/customerio-broadcasts.ts
import { APIClient, RegionUS } from "customerio-node";

const api = new APIClient(process.env.CUSTOMERIO_APP_API_KEY!, {
  region: RegionUS,
});

// Trigger a broadcast to a pre-defined segment
async function triggerProductUpdateBroadcast(version: string, changelog: string) {
  await api.triggerBroadcast(
    42,                           // Broadcast ID from dashboard
    { version, changelog },       // Data merged into Liquid template
    { segment: { id: 15 } }      // Target segment (defined in dashboard)
  );
}

// Trigger broadcast to specific emails
async function triggerBroadcastToEmails(
  broadcastId: number,
  emails: string[],
  data: Record<string, any>
) {
  await api.triggerBroadcast(
    broadcastId,
    data,
    {
      emails,
      email_ignore_missing: true,  // Don't error on unknown emails
      email_add_duplicates: false,  // Skip if user already in broadcast
    }
  );
}

// Trigger broadcast to specific user IDs
async function triggerBroadcastToUsers(
  broadcastId: number,
  userIds: string[],
  data: Record<string, any>
) {
  await api.triggerBroadcast(broadcastId, data, { ids: userIds });
}

Feature 4: Segment-Driving Attributes

Segments in Customer.io are data-driven — they automatically include/exclude people based on attributes you set via identify().

// services/customerio-segments.ts
import { TrackClient, RegionUS } from "customerio-node";

const cio = new TrackClient(
  process.env.CUSTOMERIO_SITE_ID!,
  process.env.CUSTOMERIO_TRACK_API_KEY!,
  { region: RegionUS }
);

// Update attributes that drive segment membership
async function updateEngagementAttributes(userId: string, metrics: {
  lastActiveAt: Date;
  sessionCount: number;
  totalRevenue: number;
  daysSinceLastLogin: number;
}) {
  await cio.identify(userId, {
    last_active_at: Math.floor(metrics.lastActiveAt.getTime() / 1000),
    session_count: metrics.sessionCount,
    total_revenue: metrics.totalRevenue,
    days_since_last_login: metrics.daysSinceLastLogin,
    engagement_tier: metrics.sessionCount > 50 ? "power_user"
      : metrics.sessionCount > 10 ? "active"
      : "casual",
  });
}

// Segment examples built in dashboard:
// "Power Users": engagement_tier = "power_user"
// "At Risk": days_since_last_login > 30 AND plan != "free"
// "High Value": total_revenue > 500
// "Trial Expiring": plan = "trial" AND trial_end_at < now + 3 days

Feature 5: Merge Duplicate People

// Merge a secondary (duplicate) person into a primary person.
// The secondary is deleted permanently after merge.
async function mergeUsers(
  primaryId: string,
  secondaryId: string,
  identifierType: "id" | "email" | "cio_id" = "id"
) {
  await cio.mergeCustomers(
    identifierType,
    primaryId,
    identifierType,
    secondaryId
  );
  // Secondary person is permanently deleted.
  // Their attributes and activity merge into the primary.
}

Feature 6: Suppress and Delete People

// Suppress: user stays in system but receives no messages
async function suppressUser(userId: string): Promise<void> {
  await cio.suppress(userId);
}

// Delete: remove user entirely from Customer.io
async function deleteUser(userId: string): Promise<void> {
  await cio.destroy(userId);
}

Error Handling

Error	Cause	Solution
`422` on transactional	Wrong `transactional_message_id`	Verify template ID in Customer.io dashboard
Missing Liquid variable	`message_data` incomplete	Ensure all `{{ data.x }}` variables are in `message_data`
Broadcast `404`	Invalid broadcast ID	Check broadcast ID in dashboard Broadcasts section
Segment not updating	Attribute type mismatch	Dashboard segments compare types strictly — number vs string matters
Merge fails	Secondary person doesn't exist	Verify both people exist before merging
