If your emails aren't reaching your audience, nothing else matters. Warmy.io is an AI-powered email warmup and deliverability platform that makes sure your emails land in the inbox — not the spam folder.

Warmy.io uses its proprietary AI engine, Adeline, which processes over 20 million daily decisions to adjust your warmup strategy based on your domain's sending patterns, business type, and current reputation — adapting in real time so your sender reputation keeps growing automatically.

Whether you're running cold outreach, email marketing campaigns, or growing a business newsletter, Warmy.io handles the technical side so you can focus on what you're sending, not whether it's being seen. You can even customize warmup pace, topics, and language to match your specific needs, making it one of the most flexible tools in the category.

Warmy.io also offers a 7-day free trial so you can experience the results before committing.
