AI-Powered Outbound Lead System: A2P, Apify, n8n & GoHighLevel for Digital Agency Client
We built a fully automated outbound engine — scraping, AI enrichment, validation, deduplication, and CRM nurture — so qualified leads flow in without manual work.

TL;DR
- ExoraLeads built a fully automated outbound lead generation system combining Apify, n8n, Hunter.io, Supabase, and GoHighLevel.
- The workflow scrapes ICP-matched leads, enriches them with an AI agent, validates emails via Hunter.io, and deduplicates against existing CRM contacts before creation.
- A2P 10DLC SMS verification and SPF/DKIM/DMARC email authentication were configured to maximise deliverability across cold outbound channels.
- A GoHighLevel SaaS snapshot lets new client accounts be provisioned with the full automation stack in minutes, not hours.
- Smart lists trigger behaviour-based nurture sequences automatically — no manual follow-up required at any stage.
- Built by ExoraLeads, a UK-based AI automation agency specialising in outbound systems, CRM automation, and lead generation infrastructure.
The Challenge: Manual Outbound Doesn't Scale
A digital agency client needed a complete outbound sales infrastructure built from scratch — one capable of scraping targeted leads, enriching and validating contact data, deduplicating against an existing CRM, and pushing qualified prospects into a GoHighLevel automation pipeline with full nurture sequences.
Before this build, outbound depended entirely on manual effort:
- No systematic way to source ICP-matched leads
- No email validation layer — cold emails were landing in spam
- No deduplication against existing CRM contacts
- No automated follow-up after initial outreach
- Zero pipeline visibility over lead progression
What We Built: A Fully Automated Outbound System
A2P 10DLC SMS Verification
We registered and configured A2P (Application-to-Person) 10DLC campaign verification — mandatory for business SMS in the US market. Without it, carriers filter or block messages outright. We handled brand registration, campaign use-case submission, and carrier vetting end to end.
Apify Lead Scraping
We configured Apify actors to scrape targeted lead lists that match the client's ideal customer profile (ICP), with scheduled runs automatically feeding fresh leads into the pipeline — no manual list-building.
n8n AI Agent Enrichment
We built an n8n Workflow with an AI agent layer that enriches raw scraped data automatically — cross-referencing company data, identifying decision-maker names and job titles, and standardising formatting before validation.
Hunter.io Email Validation
Every email is validated through Hunter.io before entering the CRM — checking deliverability, catching disposable addresses, and assigning confidence scores. Only passing leads progress, protecting sender reputation and keeping bounce rates below spam-trigger thresholds.
Supabase Deduplication
Before any lead reaches GoHighLevel, the workflow queries a Supabase table of existing CRM contacts. Matching emails or phone numbers are flagged and skipped — no duplicate contacts, no wasted outreach spend.
GoHighLevel REST API Integration
Direct GHL REST API calls handle two functions: secondary deduplication at the CRM layer, and automatic contact creation with enriched fields mapped to custom GHL properties, correct pipeline stage assignment, and nurture-
sequence tagging. No CSV imports, no manual data entry.
Cold Email Infrastructure: DNS + Deliverability
We configured outbound cold email via GHL's mail system with full DNS authentication — SPF, DKIM, and DMARC — on the client's domain. Every record was validated with mail-testing tools before any campaign went live.
GoHighLevel SaaS Snapshot & Auto-Onboarding
We built a GoHighLevel SaaS snapshot — a pre-configured template covering pipeline stages, automations, nurture sequences, and reporting — deployable to new sub-accounts instantly. New client accounts are provisioned in
minutes instead of hours, the infrastructure that lets an agency scale without scaling headcount 1:1.
Smart Lists & Behaviour-Based Nurturing
Smart lists dynamically segment contacts by engagement — email opens, link clicks, SMS replies, pipeline movement. Cold leads get a 5-step email sequence; engaged-but-unbooked leads get SMS follow-up; stalled contacts get re-engagement after 14 days of inactivity — fully automatic.
The Result
- Zero to fully automated outbound infrastructure — sourcing, enrichment, validation, deduplication, and nurture with no manual steps
- Significantly improved cold email deliverability after DNS authentication
- New client onboarding reduced to minutes via SaaS snapshot
- Full pipeline visibility at every lead stage
What This Means for UK Agencies and B2B Businesses
Before any lead reaches GoHighLevel, the workflow queries a Supabase Table of existing CRM contacts.
Matching emails or phone numbers are flagged and skipped — no duplicate contacts, no wasted outreach spend. If your outbound process involves building lists manually, copying data between tools, or following up by hand — every one of those steps can be automated.
This is the same stack we deploy for UK agencies and B2B Businesses systematising outbound: see our full AI automation services, or how We apply similar principles in our AI voice agent case study.
For businesses focused on inbound instead, our lead generation service and local SEO work complement this outbound system well.
