Reply.io current baseline
Beyond sequence automation, it sells "Jason," a fully automated AI SDR add-on priced separately from the core platform, and exposes the platform programmatically through a REST API (v3, Bearer-token auth) and an official remote MCP server for AI clients like Claude and Cursor.
- Multichannel sequences across email, LinkedIn, calls, SMS, and WhatsApp (semi-automation)
- Audience discovery and B2B contact database with intent signals (hiring activity, LinkedIn engagement, tech stack changes)
- LinkedIn and Sales Navigator prospecting with native filters
- Contact enrichment and scoring
- Website visitor tracking/identification
- Published starting point
- $49/user/month (Email Volume plan, billed annually)
- Setup
- 30m setup assessment
- Developer access
- API documentation, MCP documentation
When to replace Reply.io
The entry Email Volume plan is priced by active contacts/month (starting at 1,000) rather than by unlimited sending, so high-volume outbound teams will need to size up quickly; LinkedIn automation and Calls/SMS are unbundled add-ons at $69/mo and $29/mo per account on top of the base seat price, so a team wanting true all-channel coverage on the cheap plan will pay more than the advertised $49/user headline. Teams of 20+ are explicitly routed to a custom/contact-sales tier for the API/whitelabel features, so the self-serve pricing does not apply once you scale past that.
