Amplemarket

Duo is Amplemarket's AI sales copilot that researches prospects, analyzes company signals, and drafts personalized outreach referencing context like recent job changes, funding announcements, or tech stack adoption. On Growth and Elite plans, Duo Voice generates AI voice messages and Duo Inbox automates reply handling and categorization.

Amplemarket tracks 100+ intent signals including job changes, funding events, hiring patterns, technology adoption, and competitive intelligence, surfacing accounts actively showing buying behavior. Reps wake up to a prioritized list of accounts to engage based on real-time signal activity rather than static lists.

The proprietary database contains 200M+ AI-verified contacts with 70M+ records refreshed weekly, and Amplemarket reports 96.5% phone accuracy and sub-3% email bounce rates (self-reported, not independently verified). Data enrichment and email validation are built directly into prospecting workflows, reducing reliance on separate data providers.

Build sequences spanning email, LinkedIn (connection requests, messages, InMails), phone, SMS, and video in a single workflow, with branching logic based on engagement. The social prospecting layer handles LinkedIn automation with rate limiting and randomization to reduce account restriction risk.

Dedicated deliverability infrastructure including inbox rotation, warmup, DMARC/SPF/DKIM monitoring, and sender reputation scoring via the Domain Health Center. The Deliverability Booster automatically pauses or adjusts sending when reputation metrics drop, protecting domain health at high-volume outbound scale.
