Overview

Duo Inbox is an AI-powered email assistant that enables sales teams to respond instantly to prospect questions and objections. Part of Amplemarket's Intelligence suite, it leverages large language models (LLMs) and retrieval-augmented generation (RAG) to create personalized, relevant responses that sound like you while saving significant time on email management.

Why Duo Inbox?

In today's fast-paced sales environment, managing a high volume of prospect emails can quickly become overwhelming and time-consuming. Duo Inbox was developed to help sales teams save up to 6 hours per week by automating email drafting, ensuring that each message retains a human touch while being both timely and engaging. The system not only generates primary responses but also suggests follow-up options to keep conversations flowing and improve lead-to-opportunity conversion rates.

How It Works

Duo Inbox follows a three-step process to generate high-quality, contextually appropriate responses:

1. Identify Common Questions – Curate a list of common questions and objections that your sales reps receive from prospects.
2. Add Best-Performing Replies – Provide your top replies for those questions as instructions to the AI Replier.
3. Generate Email Drafts – The AI email assistant automatically generates replies whenever a new email comes from a prospect.

Architecture

Behind the scenes, Duo Inbox employs a sophisticated architecture with multiple components working together:

Core Components

At the heart of Duo Inbox is the AI Replier Service, which serves as the central component that processes email threads and generates appropriate responses. This works in tandem with the Battlecards Service, which manages the knowledge base of information used to inform these responses.

The system leverages sophisticated LLM Integration through a router that can direct requests to different language models, with primary and fallback options ensuring resilience. All of this is supported by a Vector Database that provides efficient storage and retrieval of relevant information from the knowledge base, enabling quick access to the most pertinent data for each response.

Processing Pipeline

The AI Replier follows a sophisticated 6-step process to generate high-quality responses. It begins by validating the email thread, ensuring proper structure of input data and inferring missing information when possible. Next, it processes battlecards, preparing the knowledge base information for use in response generation.

In the third step, it generates RAG queries to retrieve relevant information from the knowledge base based on the email content. This is followed by creating a scratchpad, an intermediate reasoning step to identify questions, determine if there's sufficient information, and filter the most relevant knowledge.

The fifth step involves generating the actual reply, using the scratchpad, filtered knowledge, and email thread to create a primary response and follow-up suggestions. Finally, it builds the final response, packaging the reply, follow-ups, and metadata into a structured response for delivery.

Adoption of Duo Inbox has delivered significant results for sales teams:

• Up to 75% reduction in time spent on email replies
• Improved lead-to-opportunity conversion rates
