WarmySender

WarmySender is an all-in-one cold email and outreach platform that combines domain warmup, multi-step sequences, and a 200M+ B2B lead database — so you can warm, send, and manage replies from one dashboard.

What is WarmySender?

WarmySender is an all-in-one outreach platform built for cold email and multichannel sales. Where most businesses stitch together separate tools for warmup, sending, and lead sourcing, WarmySender covers the full stack in one dashboard: it warms your sending mailboxes with A.H.D.E. (Authentic Human Deep Engagement), a warmup method that triggers multi-turn conversations up to five replies deep and reports a 99.4% inbox placement rate across 80,000+ warmup emails. It runs multi-step cold-email sequences with A-Z testing across up to 26 subject variants, conditional branching, and a visual sequence builder, plus a 200M+ verified B2B lead database searchable by role, company, industry, and geography. Bounce Shield verifies every address before it enters a sequence, and a pre-send spam score checker flags deliverability risk while you're still drafting. The AppSumo lifetime deal is a Plus Exclusive running tiers from $49 (10k emails/mo) to $399 (100k emails/mo), with a 60-day refund. LinkedIn and Instagram outreach are optional paid add-ons rather than included. For solo founders and small teams who want warmup, sending, and lead sourcing together at a fraction of Instantly or Smartlead's price, WarmySender is strong value; teams needing the deepest automation or that already run LinkedIn-heavy outreach may need to budget for the add-ons.
