About WarmySender

Run your outreach on autopilot with AI agents — cold email, email warmup, LinkedIn, WhatsApp, Instagram and multichannel sequences, plus real-time email verification.

What WarmySender Is

WarmySender is an agentic-first outreach platform. You run cold email, email warmup, LinkedIn, WhatsApp, Instagram and multichannel sequences from one workspace, with real-time email verification and a 200M+ B2B lead database built in. Connect Claude, ChatGPT, Cursor, Codex, OpenClaw or Hermes Agent — or any agent that speaks MCP — and your agent can build, launch and manage campaigns on every channel, create and enroll prospects, verify email addresses and tune warmup, all in plain language. The agent never sends a message itself and can never raise a limit: creating or launching only hands the campaign to WarmySender's scheduler, which paces every email, LinkedIn, WhatsApp and Instagram action inside safe caps and the gradual ramp, no matter who is driving. Connecting and disconnecting accounts stays in the app. Plans start at $14.99/mo. View current pricing.

Our Mission

WarmySender exists to make professional outreach accessible to every business. We believe that reaching the right inbox should not require enterprise budgets or deep technical expertise — and that describing what you want in plain language should be enough to run a campaign safely. Our platform combines email warmup, cold email campaigns, LinkedIn, WhatsApp and Instagram outreach, multichannel sequences, real-time email verification and a B2B leads database in a single, affordable tool that an AI agent can drive end to end.

Our Story

WarmySender was founded in 2024 after our team experienced the frustration of poor email deliverability firsthand. Cold emails were landing in spam, outreach campaigns were underperforming, and the available tools were either too expensive or too fragmented. We saw an opportunity to build something better: a unified outreach platform that prioritizes deliverability from the ground up.

What started as an email warmup solution quickly grew into a full outreach platform. Today, WarmySender handles email warmup, multi-step cold email campaigns, LinkedIn, WhatsApp and Instagram outreach, multichannel sequences, real-time email verification, and access to a 200M+ B2B lead database — all from a single dashboard, and all drivable by an AI agent, starting at $14.99/mo.

What content does WarmySender publish?

WarmySender has published 600+ expert articles on email deliverability, cold email strategies, LinkedIn outreach, and B2B sales — spread across the WarmySender blog, its in-depth guides, comparisons and glossary.

How does WarmySender measure deliverability?

WarmySender measures deliverability from warmup mail. Each day it checks whether the warmup emails your mailboxes exchange arrived in the inbox or the spam folder, and turns that into a per-mailbox inbox rate, spam rate and health score. Those figures describe a sending account's reputation over time — they are not a measure of where an individual campaign email landed, because once a campaign email is accepted by the recipient's mail server no sending tool can see which folder or tab it was filed into. For campaigns you see delivery, bounce and rejection data, including messages a recipient's mail server refused as spam.
