AI-powered cold outreach that lands in the inbox

The Problem

Running cold email campaigns is a nightmare of disconnected tools, manual follow-ups, and inbox deliverability anxiety. Sales teams juggle spreadsheets of prospects, hand-craft sequences across multiple sending accounts, and have no idea if their emails are actually reaching anyone.

The Solution

Without AI personalization, messages feel generic and get ignored, while unmonitored inbox health quietly tanks your sender reputation..

What It Does

🔀

Multi-Step Sequence Builder

Design branching email sequences with A/B variants, send windows, timezone-aware scheduling, and auto-triggered subsequences based on reply classification.

🧠

AI Personalization Engine

Claude generates prospect dossiers, icebreakers, and personalized email copy using enrichment data, with full token and cost tracking per operation.

🛡️

Inbox Health Dashboard

Monitor SPF, DKIM, and DMARC status across all sending accounts with real-time bounce rates, complaint rates, and warmup progress.

✅

Human-in-the-Loop Review Queue

Every AI-drafted email passes through a review queue where you can approve, edit, or reject before it sends, keeping your brand voice intact.

📬

Unified Reply Inbox

IMAP-synced replies are auto-classified by AI as interested, out-of-office, unsubscribe, or wrong person, so you only see the conversations that matter.
