Run your outreach on autopilot with AI agents — cold email, email warmup, LinkedIn & Instagram outreach in one platform
WarmySender combines five outreach pillars in a single tool: cold email campaigns, peer-to-peer email warmup, LinkedIn outreach automation, Instagram DM outreach, and multichannel sequences that mix email, LinkedIn, and Instagram touches. Instagram DM outreach is available as a per-seat add-on channel that runs standalone or inside multichannel sequences. 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.
The five pillars
Cold emailing — multi-step cold email campaigns with follow-ups, A-Z subject testing, conditional branching, spintax, and merge tags. Bounce protection runs before send to keep sender reputation clean.
Email warmup — a peer-to-peer warmup network where real mailboxes exchange real conversations. Multi-turn threads, automatic spam-folder rescue, and per-mailbox health monitoring train inbox placement on Gmail, Microsoft 365, Outlook.com, Yahoo, and any IMAP/SMTP provider.
LinkedIn outreach — automated connection requests, messages, and InMails through secure OAuth (no password sharing). A multi-week warmup ramp, conservative per-account daily limits, and a dedicated proxy per account keep profiles inside LinkedIn's safety thresholds.
Instagram outreach — a per-seat add-on that brings Instagram DM outreach into the same platform: follow, view profile, like, comment, and send direct messages. Every account runs inside a conservative combined budget of up to 100 actions per day and 10 per hour, with human-like spacing and a gradual ramp for new accounts.
Multichannel — sequences that combine email, LinkedIn, and Instagram steps with conditional branching. Replies from every channel arrive in a unified inbox so reps work one queue, not many.
Instagram outreach (add-on channel)
An optional per-seat Instagram add-on brings Instagram DM outreach into the same platform: follow, view profile, like, comment, and send direct messages. Every account works inside a conservative combined safety budget — up to 100 actions per day and 10 per hour across all action types — with human-like spacing between actions and a gradual ramp for new accounts. Replies to inbound DMs are uncapped, and Instagram steps drop straight into multichannel sequences alongside cold email and LinkedIn.

Public REST API and a Model Context Protocol (MCP) server so cold email, warmup, LinkedIn, Instagram, and multichannel sequences are reachable from Claude Desktop, Claude Code, Cursor, Windsurf, Zed, and any MCP-compatible AI assistant.
How email warmup works
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.
How LinkedIn outreach works
LinkedIn accounts connect via secure OAuth — no credentials are stored. 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.
How Instagram outreach works
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 the Instagram outreach guide for how it works end to end.
Pricing
Plans are tiered by sending volume rather than seat count. LinkedIn 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.
Who uses WarmySender
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 Instagram DM outreach, and founders or consultants booking meetings without juggling separate tool stacks.
