eration to reply handling.

This system is designed to remove 90%+ of manual work in B2B outreach and replace it with intelligent automation.

What it does:

Accepts incoming leads via webhook

Enriches and finds emails using multiple providers (Prospeo, [Hunter.io](http://Hunter.io), Dropcontact + AI fallback)

Validates emails automatically (NeverBounce)

Scores leads (low / medium / high)

Generates personalized cold emails using AI

Sends outreach via **[GMAIL](https://www.linkedin.com/in/kevork-lepedjian/#)**

Runs multi-step follow-up sequences (Day 2, 4, 7)

Classifies replies using AI (interested / not\_interested / not\_now)

Automatically routes actions based on intent

Logs everything into Google Sheets

Sends real-time Slack notifications

This is part of my deeper focus on building AI-powered revenue systems and GTM automation workflows that replace repetitive sales operations with intelligent agents.

With the cold emails going straight out through the Gmail API plus the Day 2/4/7 follow-ups, what enforces a daily volume limit per mailbox, and what stops a follow-up to someone who bounced or unsubscribed? NeverBounce covers the address up front, but I’m curious whether anything happens between the AI draft and the send. Has anything gone wrong there yet?
