An email marketing platform by MediaBoxEnt Technologies with a genuinely free plan: 250 contacts, 1,000 emails/month, 1 list, 1 user, 1 automation, no time limit. Paid plans add your own branding, an AI writing assistant (first drafts, subject lines, rewrites), multi-step automations, API/webhooks, an MCP server, and up to 10 independent workspaces for managing multiple brands from one login. Supports sending one campaign in up to six languages (translations share the AI assistant allowance), double opt-in, one-click unsubscribe, and Google Analytics tagging. MBX Reach is an official connector in the Claude directory. Note: AI-generated copy and translations require human review; free plan includes MBX Reach branding in the footer; sending pauses at plan limits until the month changes or you upgrade.
