OutreachAI: AI-Powered Multi-Channel Sales Outreach Engine with A/B Testing & Email Tracking
Client Context
Internal product built by RapidNexTech to demonstrate full-stack AI integration capabilities — from LLM-powered content generation to production email infrastructure and real-time event tracking.
The Business Challenge
Building an end-to-end outreach automation system that maintains genuine personalization at scale — integrating AI content generation, production email sending, real-time event tracking, and multi-channel message management into a cohesive, secure platform.
The Bottlenecks (Before)
- Manual research per lead takes 15-30 minutes before writing a single email
- Generic outreach templates result in low response rates and poor engagement
- No way to A/B test messaging angles without complex tooling
- Follow-ups are forgotten or sent inconsistently
- Zero visibility into whether prospects opened or clicked emails
- Scaling outreach means hiring more SDRs, not building smarter systems
The Solution (After)
- AI-powered research summarizes company context in seconds using Firecrawl web scraping
- Gemini AI generates 6 personalized message types with 2 strategic A/B variants each
- Auto-tone selection adapts messaging style based on industry, location, and sentiment analysis
- Automated 3-day and 7-day follow-up scheduling with one-click activation
- Real-time email tracking with delivery, open, click, and bounce monitoring via Resend webhooks
- CSV bulk import processes hundreds of leads with parallel AI generation
Engineering the Solution
We engineered a full-stack system combining Supabase Edge Functions for serverless AI processing, Firecrawl for automated web research, Google Gemini for context-aware message generation, and Resend for production email delivery with webhook-based tracking. PostgreSQL Row Level Security ensures complete data isolation, while the React frontend provides an intuitive interface for managing the entire outreach lifecycle.
