AI-powered multichannel sales outreach with autonomous SDR agents

Designed for sales teams and agencies that need scalable, high-deliverability outreach rather than manual one-off emailing.

About
Reply.io is a sales engagement and cold email platform that layers AI on top of traditional outbound workflows. It’s built for B2B sales teams and agencies that need to generate leads at scale, run structured outbound campaigns, and reliably turn website or list-based traffic into meetings.
The platform combines data sourcing, multichannel outreach, and meeting scheduling in one place. You can discover and enrich B2B contacts, push them into sequences spanning email, LinkedIn, SMS, calls, WhatsApp, and Zapier-connected channels, and let Reply’s AI SDR agents help with targeting, copy generation, and follow-up. It’s delivered as a web platform with a Chrome-based email search extension, and integrates with CRMs, Calendly, Gmail (via API), Google Postmaster, and other tools.
Reply.io leans into agentic behavior more than many traditional sales engagement tools. The AI SDR component can propose audiences, generate outbound sequences across multiple channels, and automatically handle basic email replies and meeting booking once prospects respond. For teams focused on volume outbound, this can significantly reduce manual SDR workload while still keeping everything visible in a unified inbox and CRM-connected pipeline.
However, it’s still very much a sales-specific platform, not a general-purpose AI assistant. According to the site, it’s optimized for cold outreach, deliverability, and structured sequences, not for running complex custom business workflows outside sales. Details on the underlying AI models, data retention, and privacy policies aren’t provided on this page, so security-conscious or highly regulated organizations will need to review separate documentation. Pricing is partially clear (there is a Multichannel plan starting at $89 per user/month billed annually and a free, no-credit-card trial), but the full tier structure for Sales Outreach, AI SDR, and Agency plans isn’t fully readable here. Teams that don’t do outbound sales, or that only send a small number of highly personalized, manual emails, are unlikely to get full value from this tool.
Handles multi-step tasks with guidance
Overall agenticness level: Level 2 (Score: 11/20).
Reply.io, particularly via its Jason AI SDR, is a capable, domain-specific agent for outbound sales. It can autonomously run multi-step, multichannel outreach campaigns, personalize and adapt messaging, handle replies, and book meetings while updating CRM and calendar systems. Its autonomy is strong within the sales engagement workflow but constrained to user-defined campaigns and goals. Adaptation and safety characteristics are present but not described in sufficient depth to score higher.
Dimension scores:
- Action Capability: 3/4
- Autonomy of Control Flow: 3/4
- Adaptation and Recovery: 2/4
- State and Continuity: 2/4
- Safety and Observability: 1/4
