This platform automates outbound sales and partnership outreach using AI and workflow orchestration. Each phase is isolated into its own workflow, ensuring fault tolerance, scalability, and auditability.
- Automate lead sourcing from Apollo
- Generate highly personalized messages using AI
- Send LinkedIn invites and emails programmatically
- Track outreach state across systems
- Respond intelligently to inbound LinkedIn messages
| Criteria | Condition |
|---|---|
| Lead Creation | Leads stored in Google Sheets |
| Personalization | AI icebreakers generated |
| Outreach | LinkedIn & email sent |
| Tracking | Status updated in Sheets & DB |
| Reply Handling | AI replies logged and sent |
- n8n (self-hosted or cloud)
- Google Workspace account
- Apollo.io account
- Apify API token
- Unipile LinkedIn API access
- OpenAI API key
- PostgreSQL database
- Clone repository
- Configure environment variables
- Import workflows into n8n
- Configure credentials
- Activate workflows sequentially
This system relies on a tightly integrated set of third-party APIs. Each API serves a distinct, isolated responsibility within the outreach lifecycle. All integrations are orchestrated via n8n using secure credentials and scoped permissions.
| API / Service | Purpose | Workflow Phase | Data In | Data Out |
|---|---|---|---|---|
| Apollo API | Lead discovery & filtering | 01 – Lead Acquisition | ICP criteria | Company & profile URLs |
| Apify API | Profile & data scraping | 01 – Lead Acquisition | Apollo URLs | Structured lead data |
| SerpAPI | Public web research | 02 – AI Personalization | Name, company | Contextual insights |
| OpenAI API | AI personalization & replies | 02, 03, 05 | Context prompts | Structured messages |
| Unipile API | LinkedIn automation | 03, 04, 05 | Profile ID, message | Delivery status |
| Gmail API | Email outreach | 03 – Outbound Outreach | Email content | Send confirmation |
This system is backend-driven. Google Sheets acts as the operational UI:
- Lead visibility
- Status tracking
- Audit and compliance review
- LN_invitationSent: YES / NO
- LN_invitationAccepted: YES / NO
- EmailSent: YES / NO
- LN_noofmessages: Integer
- End-to-end automated B2B outreach lifecycle
- AI-driven lead research and contextual personalization
- Multi-channel execution (LinkedIn + Email)
- Human-like randomized delays to reduce automation risk
- Stateful lead and conversation tracking
- Webhook-driven real-time engagement handling
- Structured AI outputs with deterministic parsing
- Audit-ready logging using Google Sheets and PostgreSQL
