Ballast

Ballast is an outbound cold email platform engineered to eliminate artificial seat taxes, workspace markups, and mailbox caps. Instead of charging extra for every connected account or team member, Ballast uses a simple volume model starting at $19 a month where teams pay strictly for the emails they actually send. Every plan includes unlimited mailboxes, unlimited team seats, automated warm-up, and client workspaces.

The platform connects across Google Workspace, Microsoft 365, and custom SMTP servers with built-in deliverability protection. It spaces out sending with human-paced throttling, monitors SPF, DKIM, and DMARC health nightly, and automatically pauses campaigns if bounce rates climb before domains suffer reputation damage. A unified Unibox automatically categorizes incoming responses into actionable labels like interested, meeting booked, and out of office.

Ballast also includes a native Model Context Protocol (MCP) server, allowing developers and growth engineers to connect AI agents in Claude, Cursor, and ChatGPT to run campaigns, draft sequences, and inspect domain health via simple prompts. The system features a fast import engine that maps columns and filters suppressed or duplicate leads directly from Instantly, Smartlead, Lemlist, Apollo, and Clay.

Ballast is built for lead generation agencies, B2B sales teams, growth marketers, and bootstrapped SaaS founders who want dependable cold outreach without paying bloated recurring software bills.
