When your agent uses it

  • Building automated email campaigns
  • Creating sequences
  • Managing outreach through Apollo
  • With phrases like apollo email sequence

Example prompts

  • “apollo email sequence”
  • “apollo outreach”
  • “apollo campaign”
  • “/apollo-core-workflow-b”

Requirements

  • A credential in APOLLO_API_KEY
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(npm:*), Bash(pip:*), Grep

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Search for Existing Sequences
  2. Get Email Accounts for Sending
  3. Add Contacts to a Sequence
  4. Update Contact Status in a Sequence
  5. Create and Manage Contacts for Sequences
  6. Full Outreach Pipeline

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash(npm:*)
    • Bash(pip:*)
    • Grep

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.apollo.io

    Also links to:

    • docs.apollo.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • APOLLO_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Apollo Core Workflow B loads about 2.1k tokens when it runs, and up to ~4.3k if it reads all its reference files. Until then it costs about 80 tokens; SKILL.md has 384 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~80
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Apollo Core Workflow B: Email Sequences & Outreach

Overview

Build Apollo.io email sequencing and outreach automation via the REST API. Sequences in Apollo are called "emailer_campaigns" in the API. This covers listing, searching, adding contacts, tracking engagement, and managing sequence lifecycle. All endpoints require a master API key.

Prerequisites

  • Completed apollo-core-workflow-a (lead search)
  • Apollo account with Sequences feature enabled
  • Connected email account in Apollo (Settings > Channels > Email)
  • Master API key (not standard)

Instructions

Step 1: Search for Existing Sequences
typescript
// src/workflows/sequences.ts
import axios from 'axios';

const client = axios.create({
  baseURL: 'https://api.apollo.io/api/v1',
  headers: { 'Content-Type': 'application/json', 'x-api-key': process.env.APOLLO_API_KEY! },
});

export async function searchSequences(query?: string) {
  const { data } = await client.post('/emailer_campaigns/search', {
    q_name: query,       // optional name filter
    page: 1,
    per_page: 25,
  });

  return data.emailer_campaigns.map((seq: any) => ({
    id: seq.id,
    name: seq.name,
    active: seq.active,
    numSteps: seq.num_steps ?? seq.emailer_steps?.length ?? 0,
    stats: {
      totalContacts: seq.unique_scheduled ?? 0,
      delivered: seq.unique_delivered ?? 0,
      opened: seq.unique_opened ?? 0,
      replied: seq.unique_replied ?? 0,
      bounced: seq.unique_bounced ?? 0,
    },
    createdAt: seq.created_at,
  }));
}
Step 2: Get Email Accounts for Sending

Before adding contacts to a sequence, you need the email account ID that will send the messages.

typescript
export async function getEmailAccounts() {
  const { data } = await client.get('/email_accounts');

  return data.email_accounts.map((acct: any) => ({
    id: acct.id,
    email: acct.email,
    sendingEnabled: acct.active,
    provider: acct.type,  // "gmail", "outlook", "smtp"
    dailySendLimit: acct.daily_email_limit,
  }));
}
Step 3: Add Contacts to a Sequence

The add_contact_ids endpoint enrolls contacts into an existing sequence. You must specify which email account sends the messages.

typescript
export async function addContactsToSequence(
  sequenceId: string,
  contactIds: string[],
  emailAccountId: string,
) {
  const { data } = await client.post(
    `/emailer_campaigns/${sequenceId}/add_contact_ids`,
    {
      contact_ids: contactIds,
      emailer_campaign_id: sequenceId,
      send_email_from_email_account_id: emailAccountId,
      sequence_active_in_other_campaigns: false,  // skip if already in another sequence
    },
  );

  return {
    added: data.contacts?.length ?? 0,
    alreadyInCampaign: data.contacts_already_in_campaign ?? 0,
    errors: data.not_added_contact_ids ?? [],
  };
}
Step 4: Update Contact Status in a Sequence
typescript
// Mark contacts as finished or remove them from a sequence
export async function removeContactsFromSequence(
  sequenceId: string,
  contactIds: string[],
  action: 'finished' | 'removed' = 'finished',
) {
  const { data } = await client.post('/emailer_campaigns/remove_or_stop_contact_ids', {
    emailer_campaign_id: sequenceId,
    contact_ids: contactIds,
    // "finished" marks contact as completed; "removed" fully removes
  });

  return {
    updated: data.contacts?.length ?? 0,
  };
}
Step 5: Create and Manage Contacts for Sequences

Contacts must exist in your Apollo CRM before adding to sequences. Use the Contacts API to create them.

typescript
// Create a contact in your Apollo CRM
export async function createContact(params: {
  firstName: string;
  lastName: string;
  email: string;
  title?: string;
  organizationName?: string;
  websiteUrl?: string;
}) {
  const { data } = await client.post('/contacts', {
    first_name: params.firstName,
    last_name: params.lastName,
    email: params.email,
    title: params.title,
    organization_name: params.organizationName,
    website_url: params.websiteUrl,
  });

  return {
    id: data.contact.id,
    email: data.contact.email,
    name: `${data.contact.first_name} ${data.contact.last_name}`,
  };
}

// Search your CRM contacts (not the Apollo database)
export async function searchCrmContacts(query: string) {
  const { data } = await client.post('/contacts/search', {
    q_keywords: query,
    page: 1,
    per_page: 25,
  });

  return data.contacts.map((c: any) => ({
    id: c.id,
    name: c.name,
    email: c.email,
    title: c.title,
    company: c.organization_name,
  }));
}
Step 6: Full Outreach Pipeline
typescript
async function launchOutreach(
  sequenceId: string,
  leads: Array<{ firstName: string; lastName: string; email: string; title?: string; company?: string }>,
) {
  // 1. Get a sending email account
  const accounts = await getEmailAccounts();
  const sender = accounts.find((a: any) => a.sendingEnabled);
  if (!sender) throw new Error('No active email account found');

  // 2. Create contacts in Apollo CRM (or find existing)
  const contactIds: string[] = [];
  for (const lead of leads) {
    try {
      const contact = await createContact({
        firstName: lead.firstName,
        lastName: lead.lastName,
        email: lead.email,
        title: lead.title,
        organizationName: lead.company,
      });
      contactIds.push(contact.id);
    } catch (err: any) {
      // Contact may already exist — search for them
      const existing = await searchCrmContacts(lead.email);
      if (existing.length > 0) contactIds.push(existing[0].id);
    }
  }

  // 3. Add contacts to the sequence
  const result = await addContactsToSequence(sequenceId, contactIds, sender.id);
  console.log(`Added ${result.added} contacts, ${result.alreadyInCampaign} already enrolled`);

  return result;
}

Output

  • Sequence search via POST /emailer_campaigns/search
  • Email account listing via GET /email_accounts
  • Contact enrollment via POST /emailer_campaigns/{id}/add_contact_ids
  • Contact removal via POST /emailer_campaigns/remove_or_stop_contact_ids
  • Contact creation via POST /contacts and search via POST /contacts/search
  • Full outreach pipeline: create contacts, find sender, enroll in sequence

Examples

For a controlled campaign launch, select an existing approved sequence and a small, consented staging lead list. First query the sequence and active sender, then create or resolve each CRM contact without logging email addresses. Submit the contact IDs once, record only the added, already-enrolled, and rejected counts, and inspect the campaign in Apollo before enabling any send. If a contact is already active in another campaign, a sender is unavailable, or the API returns a partial result, stop that batch and resolve it manually instead of retrying enrollment blindly.
