Warmy.io — Marketing & SEO ◆

What is Warmy.io

Warmy.io is an AI-powered email deliverability tool that automates email warm-up to improve sender reputation and inbox placement. It connects to a network of real business or consumer inboxes to send and reply to messages in a natural pattern, training spam filters that your address is legitimate.

Who it is for

Ideal for sales teams, agencies, founders, and affiliates sending cold outreach at scale. Also helps those recovering from spam complaints or blacklists. Not recommended for warm email lists where deliverability is already healthy.
