Reply is an AI-first sales engagement platform built to automate and personalize outbound sales outreach across multiple channels. It enables sales development representatives and growth teams to build targeted prospect lists, launch multichannel sequences, and manage all prospect communication from a single unified workspace. From finding leads to booking meetings, Reply covers the entire outbound pipeline without requiring teams to switch between separate tools.

The platform includes a built-in B2B contact database of over 1 billion verified global contacts, spanning 150+ countries and 60+ million accounts. Users can apply filters based on job title, company size, industry, and hiring or technographic intent signals to identify and connect with their ideal customer profile. Verified emails are sourced in real time, reducing bounce rates and improving overall deliverability.

Multichannel sequences in Reply allow teams to mix and match emails, LinkedIn touchpoints, calls, SMS, and WhatsApp messages into dynamic conditional workflows. Sequences can branch based on prospect behavior and engagement, and all steps can be personalized with dynamic AI variables at scale. The built-in email deliverability suite includes inbox warm-up, SPF/DKIM/DMARC checks, custom tracking domains, and inbox rotation to maximize inbox placement.

Jason, Reply's AI SDR agent, handles prospecting, message personalization, response management, and meeting booking autonomously. The platform also provides a unified inbox to manage replies across all channels, detailed campaign analytics, CRM integrations with Salesforce, HubSpot, and Pipedrive, and a Chrome extension called Findy for in-browser lead discovery and task management. Agency and team plans support multi-client management, user access controls, and performance reporting across accounts.
