What Senders.ai is
Senders.ai helps B2B teams prepare cold-email campaigns through Claude, ChatGPT, and other MCP-capable clients. Its AI can research prospects, draft messages, create sequences, and stage campaigns, with a user approval step before emails are sent. A free account supports domain checks, email-copy analysis, campaign planning, prospect lists, and do-not-contact lists; live-prospect discovery and sending require a paid plan. Connections run through the MCP endpoint mcp.senders.ai/mcp, and the product is available on web and API. Single supports one customer-owned Gmail or Outlook mailbox, while Team supports up to five mailboxes and can connect a customer's Apollo account. Single and Team cap sending at 50 emails per mailbox per day; Business starts with one managed sender at 200 daily emails. Business also includes domain and Google Postmaster monitoring and inbox placement testing. Plans cost $50 a month for Single, $299 a month for Team, and $667 a month for Business. The company positions the service for considered outreach of tens to hundreds of emails a day, rather than high-volume cold spam.
