Overview
GrowthOps was manually processing leads: copying from form submissions to spreadsheet, scoring manually, adding to CRM, and sending emails. This took 6+ hours daily and had 15% error rate. LeadFlow automates the entire pipeline.
Process
Built n8n workflows to capture form submissions, score leads based on predefined rules, sync to HubSpot, and trigger email sequences. Implemented conditional logic for different lead types.
Key Features
Challenges & Solutions
Built modular scoring functions with clear inputs/outputs, created lookup tables for rule reference, and documented logic in workflow comments. Simplified from 50-node monster flow to 8 connected modules.
Implemented request batching, added queue/buffer system with exponential backoff, and used HubSpot webhooks for real-time updates. 100% sync success rate achieved.
Created dynamic scoring rules stored in HubSpot custom fields and a separate config document. Marketing team could update rules without touching workflows. Autonomy achieved.
Added personalization tokens (company name, industry, first name), implemented dynamic email template selection based on lead source, and A/B tested subject lines. Response rate improved to 5.3%.
