Ballast is a hosted cold email platform. Connect your own mailboxes, import leads, build sequences and send campaigns, with replies in one unified inbox. What makes it different: - Every feature on every plan. No paywalled tiers. - Unlimited mailboxes and unlimited seats. - Everything in the dashboard is also an API endpoint and an MCP tool, so your AI can run your outreach. - A free domain checker (ballast.to/check) that tests SPF, DKIM, DMARC and blocklists before you send. Sending safety comes first. No open tracking by default, one-click unsubscribe on every message, and per-mailbox pacing.
