Effortless email warmup and outreach

Hey AppSumo fam! 👋

We built WarmySender because hitting “send” on cold emails shouldn’t feel like tossing bottles into the ocean.

With our platform you can find laser-targeted leads from a 200 M-contact B2B database, warm up your inbox automatically to 99.4 % deliverability, and fire off high-converting sequences—all from one dashboard.

Prefer autopilot? Tell our AI agent what you sell in plain English and watch it spin up a full campaign, subject lines to follow-ups, in minutes. 🚀

We’re thrilled to launch on AppSumo and hand growth hackers, founders, and agencies the keys to predictable outreach.

Grab the lifetime deal, skip the spam folder, and start booking more demos today.

Let’s turn cold emails into warm relationships together! 🔥
