Automating Outbound for a Lead Generation Agency

Automated lead gen pipeline architecture with Apollo, verification, and AI email generation

Client: A high-growth B2B lead generation firm
Goal: Fully automate lead sourcing, enrichment, and outreach to scale outbound without adding headcount
Industry: Sales and Marketing Services

The Problem

The agency’s outbound team was spending too much time on repetitive tasks. Pulling leads from Apollo, cleaning datasets, verifying emails, and writing outreach copy manually slowed down campaign cycles and limited scale. They needed a system that handled the entire flow with minimal human touch, while still delivering high-quality, personalized outreach.

The Solution

Statistique designed and implemented a fully automated pipeline. Each component was modular and easy to maintain, allowing the agency to scale outreach while maintaining accuracy and personalization.


1. Lead Extraction from Apollo

Users select filters inside Apollo, copy the results URL, and the system scrapes relevant contacts including names, roles, emails, and company metadata. No CSVs or manual exports involved.

Impact: Faster lead capture and easier targeting.


2. Data Cleaning and Filtering

Contacts are screened based on rules like company size, region, or tech stack. Incomplete or duplicate records are removed automatically.

Impact: Clean, qualified datasets ready for outreach.


3. Email Verification

Emails are verified in bulk to remove risky or invalid addresses. Contacts that fail validation are excluded before any campaign begins.

Impact: Higher deliverability and domain health.


4. SEO and Website Enrichment

Each lead’s company domain is scraped to extract service details, positioning, leadership info, and SEO metrics like backlinks and domain authority.

Impact: Richer context for smarter messaging.


5. AI-Based Personalization

Using OpenAI LLMs and engineered prompts, the system generates tailored email copy that reflects each company’s digital footprint, market position, and team structure.

Impact: Hyper-personalized messages without manual copywriting.


6. Campaign Scheduling

Verified leads and AI-written emails are pushed to a scheduling engine. Outreach is timed across both email and LinkedIn, with follow-ups triggered based on recipient behavior.

Impact: Consistent multi-channel touchpoints without human coordination.


7. Feedback and Iteration

The system logs opens, replies, bounces, and click-throughs. These signals are used to improve targeting, update filters, and fine-tune message prompts.

Impact: Continuous performance improvement with no additional lift.


Results

  • Reduced manual effort by over 90 percent

  • Boosted positive reply rates by 35 to 40 percent

  • Improved list quality through real-time cleaning and verification

  • Created a repeatable system that scales across industries and geographies
