Run your outreach on autopilot with AI agents.
Connect your AI agent and just say what you want. It runs cold emailing, email warmup, LinkedIn, WhatsApp and Instagram outreach, multichannel sequences, and email verification for you — over a 200M+ B2B lead database, from one workspace. Plans start at $14.99/month with a 7-day free trial.
WarmySender is built for SDRs, founders, recruiters, lead generation agencies and growth teams who want outbound to run itself without putting a single account at risk.
HOW IT WORKS
1. Connect your AI agent. Point Claude Desktop, Claude Code, ChatGPT, Grok Bot, OpenClaw, Cursor, Windsurf or Zed at warmysender.com/mcp with a key from Settings — each ships with a one-paste install snippet. Any other MCP client that speaks Streamable HTTP (Continue, Cline, Goose, custom agents) works too. Then plug in your mailboxes, LinkedIn, WhatsApp and Instagram accounts in the app — done in minutes.
2. Tell it what you want, in plain English. "Launch a cold email campaign to these leads, follow up on LinkedIn, and DM the ones who open." Your agent builds the sequences, verifies addresses, and enrolls prospects across every channel.
3. We keep every send safe. Peer-to-peer warmup builds your sending reputation with real threaded conversations, and pulls warmup mail back to the inbox automatically if it lands in spam. The scheduler paces every email, LinkedIn touch, WhatsApp message and Instagram DM inside safe daily limits and your ramp — no matter who's driving. The agent never sends a message, DM or invite itself, and no agent and no setting can raise a limit. Connecting and disconnecting accounts always stays in the app.
4. Watch the replies roll in. Every reply lands in one unified inbox across all channels. Ask your agent to pause cold prospects, follow up with warm ones, and route hot leads wherever you work.
EVERY CHANNEL IN ONE PLATFORM
Cold email — multi-step campaigns built, launched and paced for you, with merge fields, spintax, A-Z testing across 26 variants and mailbox rotation.
Email warmup — A.H.D.E. (Authentic Human Deep Engagement): peer-to-peer threaded conversations up to 5 replies deep, always on, and unlimited on every plan.
LinkedIn — connection requests, messages, InMails and post engagement, plus post publishing and scheduling, saved audiences, multi-account rotation and per-account proxy routing, all inside per-account caps and a gradual ramp.
WhatsApp — message from your own number, on a gradual ramp up to 60 messages a day per number.
Instagram — auto-follow, like, comment and personalized DMs across rotating accounts, capped daily and hourly.
Multichannel sequences — a visual drag-and-drop builder with 8 conditional branch types, mixing email, LinkedIn, WhatsApp and Instagram steps in a single campaign.
Email verification — Bounce Shield checks every address the moment you upload it, with honest flags for catch-all domains like Outlook and Yahoo, so you know what's deliverable before you send.
200M+ B2B lead database — search, filter and enroll prospects without leaving the workspace.
Plus AI-powered subject lines, a real-time mailbox health view that flags problems before they cost you replies, analytics across email, LinkedIn and warmup, and multi-workspace and admin controls for agencies running outreach for many clients at once.
Your outreach, on autopilot.
