ARCHITECTURE BREAKDOWN

The 4-stage pipeline engineering

How we eliminated manual lead research while guaranteeing total quality control.

Stage 1 · Web Scraping & Profiling
1

Firecrawl Web Extraction

When a lead email and domain arrive via webhook, the workflow instantly calls Firecrawl's clean markdown scraping engine. It isolates primary landing content, stripping away useless Base64 images and navigational fluff to minimize LLM token costs.

Stage 2 · AI Reasoning Engine
2

DeepSeek Personalized Pitch Synthesis

The scraped website context is fed into DeepSeek. The AI analyzes the prospect's exact product offerings and pain points to craft a personalized outreach message—referencing real details instead of generic templates.

Stage 3 · Human-in-the-Loop
3

Silent Slack Approval Interface & Live Screenshot

A rich Slack block message is generated with Microlink live website preview screenshots and interactive buttons (Approve, Deny, Edit). Clicking 'Edit' opens a native Slack Modal pre-filled with the AI email draft, allowing team members to tweak text directly inside Slack.

Stage 4 · CRM & Delivery Sync

HubSpot & Google Sheets Orchestration

Upon approval, an asynchronous callback workflow triggers Gmail to send the email, logs the event to Google Sheets, creates/updates the record in HubSpot CRM, and transitions the contact lifecycle stage to "Outreach Sent".
