WarmySender is an outreach platform you can hand to an AI agent. Connect your 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. Includes a 200M+ B2B lead database. Everything works exactly the same way when you drive it yourself in the app.
Run Your Outreach on Autopilot with AI Agents
Claude, ChatGPT, Cursor, Codex, OpenClaw and Hermes Agent — plus any agent that speaks MCP — connect to WarmySender's public MCP server. Your agent can build, launch and manage campaigns on every channel, create and enroll prospects, verify email addresses, configure warmup, and read your stats, all in plain language.
Safety Built Into Every Send
The agent never sends a message, DM or invite directly, and can never raise a limit. Creating or launching a campaign only writes it and hands it to WarmySender's scheduler, which paces every email, LinkedIn action, WhatsApp message and Instagram action inside safe daily, weekly and hourly caps and a gradual ramp — whether a human or an agent triggered it. Connecting and disconnecting accounts stays in the app; it is the one thing that is not an agent tool.
Cold Email Campaigns
Multi-step sequences with automatic follow-ups, conditional branching, A/B tested message variants, and open, click and reply tracking, all paced inside safe sending windows and daily limits.
Email Warmup
Peer-to-peer warmup across real mailboxes exchanging real conversations to build sender reputation before campaigns launch. Works with Gmail, Outlook and any SMTP provider. Unlimited warmup on every paid plan.
LinkedIn Outreach
Connection requests, messages and InMails, prospect search, a unified LinkedIn inbox, multi-account rotation, and cross-account analytics — with a multi-week safety ramp and a dedicated proxy per account.
WhatsApp Outreach
Connect your own WhatsApp number and send paced, personalized 1:1 messages with follow-ups, waits and reply branches, inside conservative per-number limits.
Instagram Outreach
Direct messages, follows, profile views, likes and comments, with human-like spacing and a gradual per-account safety ramp.
Multichannel Sequences
Mix email, LinkedIn, WhatsApp and Instagram steps in one visual workflow with conditional branching, and manage every reply from one unified inbox.
Email Verification and B2B Leads
Real-time email verification in the app, over the REST API and as an agent tool, plus a 200M+ B2B lead database with search and enrichment.
Pricing
Plans from $14.99/month up to $199/month, with discounted annual and three-year terms that bring the entry plan to $4.50/month effective. A 7-day free trial with no credit card is available on the Pro and Enterprise plans. LinkedIn, WhatsApp and Instagram are per-seat add-on channels.
