Send a million emails a month through your own mailboxes. Detect replies in seconds. Let Claude draft what to say next. Bill clients on your own Stripe.
Gmail API, Microsoft Graph, and SMTP all flow through a single per-mailbox throttle. New mailboxes ramp 50 → 500 / day over 30 days. Daily limits reset at each mailbox's local midnight, so no more East Coast queues stalling at 9pm.
Gmail Pub/Sub + Microsoft Graph webhooks deliver inbounds in real time. IMAP IDLE as fallback. Every reply auto-classified: positive · OOO · question · unsubscribe · forward. Claude drafts a response in your voice while you're still reading the message.
Cross-customer warmup pool with Bronze · Silver · Gold reputation tiers. Gold only pairs with Silver+. Bad actors quarantined automatically. The quietest, most behaviour-gated deliverability moat on the market, opt-in per mailbox, included on every tier.
No other cold-email platform ships this. Sub-account billing means you stop sending invoices manually and start collecting platform fees on autopilot. Each client gets their own Stripe charge, on your connected account. End-clients never see NuMail.
Native MCP server. Drop it into Claude Desktop in 30 seconds. Fourteen agent-callable tools: build and launch campaigns, pause and resume them, add and suppress leads, check mailbox health, read the unibox and send replies, all by name. No glue code.
// Drop this in and Claude Code can run your outbound: { "mcpServers": { "numail": { "type": "http", "url": "https://www.numail.ai/api/mcp", "headers": { "Authorization": "Bearer nm_live_•••" } } } } // Then in Claude Code: ▸ Pause "Q2 outbound". ↳ pause_campaign({ campaignId:"cmp_3f" }) · paused ▸ Who replied positive this week? ↳ list_replies({ classification:"positive" }) → 14 threads · 7 awaiting a reply
NuMail is built for outbound agencies. Instantly is built for individual SDRs. SmartLead is built for resellers. EmailBison is built for low-volume founders. The differences show up where you'd hope.
