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. 200M+ B2B leads.
WarmySender runs outreach on autopilot with AI agents. It is one platform for five channels — cold email campaigns, peer-to-peer email warmup, LinkedIn outreach, Instagram DM outreach, and multichannel sequences that mix those touches — plus real-time email verification and a 200M+ B2B lead database. WhatsApp outreach is available as a per-seat add-on channel that runs standalone or inside multichannel sequences. Plans start at $14.99/month with a 7-day free trial. It is built for sales teams, lead-gen agencies, recruiters, creators, and founders who want to book meetings without paying per-user pricing for every channel.
WarmySender publishes a Model Context Protocol (MCP) server, so an AI agent can run your entire outreach in plain language: Claude, ChatGPT, Cursor, Codex, OpenClaw, and Hermes Agent — plus any agent that speaks MCP. An agent can create, launch and manage campaigns on every channel (cold email, LinkedIn, Instagram — create, start, pause, resume, enroll), create and enroll prospects, verify email addresses, configure warmup, and read stats.
What an agent can never do. The agent never sends a message, DM or invite directly, and it 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 and Instagram action inside safe daily, weekly and hourly caps and the gradual ramp — regardless of whether a human or an agent triggered it. Email verification shares the same allowance and pacing. Connecting and disconnecting accounts stays in the app; it is the one thing that is not an agent tool. Install instructions for every agent are at the AI agents install hub and the server reference is at the MCP server page.
Every plan includes real-time email verification, so a list is cleaned before it is ever sent to. Verify a single address or upload a list, and each address comes back Valid, Risky, Invalid or Unknown — Unknown results are always free. Verification is available in the app, over the public REST API, and as an agent tool, and it runs inside the same monthly allowance and steady pacing wherever it is triggered. Verified lists drop straight into a campaign without creating duplicates. See the email verifier.
An optional per-seat WhatsApp add-on brings WhatsApp messaging into the same platform. You connect your own WhatsApp number and bring the phone numbers you want to reach. Brand-new numbers start on a gradual ramp instead of sending at full speed, every account stays inside a conservative budget of up to 60 WhatsApp messages a day per number, and messages are spaced out with a natural pause rather than fired in a burst. The replies you send back are free and never count against the daily budget, and WhatsApp steps drop straight into multichannel sequences alongside cold email, LinkedIn, and Instagram.
Mailboxes connected to WarmySender exchange messages with other verified mailboxes in the network. Each warmup email pulls from a large pool of subject and body variations so spam filters cannot pattern-match on repeated content. Threads run multi-turn — replies, forwards, and follow-ups — and the system automatically rescues messages that land in spam to train providers to trust the sender. Mailboxes whose spam rate climbs are paused and excluded from the pool to protect everyone else.
LinkedIn accounts connect securely from inside the app — no credentials are stored, and connecting an account is never something an agent can do for you. New accounts start on a multi-week ramp with low daily invite and message limits, then graduate to safe maximums. Each account is paired with a dedicated proxy located near the user's real IP, drawn from a pool spanning many countries. Real-time health monitoring auto-pauses an account before LinkedIn can issue a restriction.
Instagram accounts connect through the platform's guided flow, and every action — follows, profile views, likes, comments, and direct messages — runs inside one conservative combined budget of up to 100 actions per day and 10 per hour, shared across all action types. Actions are spaced out with natural randomness rather than fired in bursts, and brand-new accounts start on a gradual ramp so they ease into outreach. DMs to people who don't follow you land in their message requests, which is the normal outcome and doesn't harm account health. Replies to inbound DMs are uncapped so live conversations never wait on the daily budget. See how to build an Instagram DM campaign.
Plans are tiered by sending volume rather than seat count and start at $14.99/month, with a 7-day free trial. LinkedIn, WhatsApp, and Instagram outreach are each sold per seat as add-ons and work alongside any plan. See the pricing page for current tier details and annual discounts.
Lead-gen agencies running multi-channel campaigns for clients, SDR teams that need email and LinkedIn from day one, recruiters sourcing candidates through multiple channels, creators and e-commerce brands running WhatsApp and Instagram DM outreach, and founders or consultants booking meetings without juggling separate tool stacks.
