Bottom line

All in one outreach account for cold email, built in warmup, LinkedIn, WhatsApp and Instagram, from $29/mo month to month or $13.05/mo billed yearly, with $12 per seat social add-ons. Its MCP server lets Claude, Cursor or another agent build and launch campaigns while WarmySender's scheduler keeps every account inside safe limits. Best for small recruiting desks and agencies that want one cheap tool instead of separate sender, warmup and LinkedIn subscriptions.

Stands out for: The agent integration is unusually deep and unusually guarded: 90 MCP tools reach campaigns on four channels, the unified inbox, lead search and verification, yet an agent can never send a message itself or raise a cap, because every action goes through the same scheduler as the web app. Recruiters also get something sales tools rarely offer, MCP tools that draft, publish and close LinkedIn Recruiter job postings and list applicants.

Watch out for: The cheapest prices need commitment: the headline month to month Pro rate is $29, and the low per month figures come from paying a year ($156.60) or three years ($313.20) up front. LinkedIn, WhatsApp and Instagram are each $12 per connected account per month on top, so a multichannel desk adds up. Automating LinkedIn and Instagram from any tool carries account restriction risk even with WarmySender's ramps and caps, and ChatGPT only gets a reduced set of MCP tools.

Overview

WarmySender is a multichannel outreach platform that combines cold email campaigns, peer to peer email warmup, LinkedIn, WhatsApp and Instagram outreach, real time email verification and a B2B database the vendor puts at more than 200 million contacts across 100+ countries, deepest in the US and Canada.

Email sends from your own Gmail, Google Workspace, Outlook, Microsoft 365 or SMTP mailboxes. Sequences support up to 26 A to Z variants per step, eight branch conditions (opens, clicks, replies, bounces and more), a drag and drop builder, a spam score checker and a unified inbox that collects email, LinkedIn, WhatsApp and Instagram replies.

Warmup runs on a peer to peer network the vendor says moves 900K+ warmup emails a month across 8,500+ mailboxes warmed to date. Messages are composed fresh from a large content library, threads run up to five replies deep, and mailboxes that start landing in spam are throttled and then removed from the pool to protect everyone else.

LinkedIn outreach is a $12 per seat add-on with a dedicated proxy per account in 20+ countries, a ramp that starts around 10 invites a day, and caps of about 200 connection requests a week for an established profile. WhatsApp and Instagram add-ons work the same way, with gradual ramps for new numbers and accounts.

The product is positioned agent first. A hosted MCP server at warmysender.com/mcp exposes 90 tools to Claude, Claude Code, Cursor, Codex, OpenClaw, Hermes Agent, Windsurf, Grok and other MCP clients, by OAuth sign in or a scoped API key, at no extra charge on paid plans. With a LinkedIn Recruiter seat the same server can create, publish and close job postings and pull applicants.

Plans are Pro at $29/mo, Enterprise at $69.99/mo and Ultimate at $199/mo month to month, with 55% off yearly and 70% off on a three year prepay. A 7-day free trial is offered, and payments are refundable within 7 days if nothing has been sent.
