What is Reply.io?
Reply.io is a sales engagement and AI SDR platform founded in 2014. It combines cold email automation with multi-channel outreach (LinkedIn, SMS, phone, WhatsApp) and AI-powered sales development. The platform’s standout feature is Jason AI — an AI agent that can autonomously find prospects, write personalized emails, manage follow-ups, and book meetings.
Reply.io is best for sales teams and agencies that want a unified platform for outreach automation and AI-assisted sales development, without needing to piece together separate tools for email, LinkedIn, and AI copywriting.
