Cold email is the highest-ROI sales channel for B2B when it works. The problem is that making it work requires a full-time SDR. Landline replaces that entire workflow with Dialtone, an autonomous AI agent that runs your cold email operation end-to-end.
What Dialtone Does
Prospect Research. Give Dialtone your ideal customer profile and it researches prospects, gathering context about their company, role, recent activity, and potential pain points.
Email Crafting. Each email is written from scratch for the specific prospect. Dialtone considers the prospect context, your value proposition, and what has worked in previous campaigns.
Sequence Management. Dialtone manages multi-step sequences: initial outreach, follow-ups with different angles, and breakup emails. Timing is optimized based on response patterns.
Reply Handling. When prospects respond, Dialtone classifies the reply (interested, objection, not now, unsubscribe) and either continues the conversation or routes to your sales team.
Multi-Tenant for Agencies
Landline supports full organizational isolation with role-based access. Agencies running cold email for multiple clients get separate workspaces, separate sending domains, and separate analytics.
Deliverability Built In
Dialtone manages sending infrastructure: domain warm-up, volume ramping, bounce monitoring, and spam-score checking. It rotates sending accounts and automatically pauses campaigns if deliverability drops.
Get Started
Landline is live at landline.aiknol.com. Set up your first campaign and let Dialtone start prospecting.
Built with FastAPI, React, Vite, PostgreSQL, SQLAlchemy, and OpenRouter AI.
