# Warmy review

AI-driven email warm-up and deliverability platform for marketers and sales teams sending cold or bulk email.

By Noah — last updated & pricing verified October 24, 2026.

> Warmy is a SaaS tool that improves email deliverability by automatically warming up sending domains and IPs, testing inbox placement, and flagging DNS or reputation problems before a sender's real campaigns go out. It is used by marketers, sales development teams, agencies, and e-commerce brands that send cold outreach or high-volume marketing email and need messages to land in the primary inbox instead of spam.

## Facts

- Website: https://warmy.io
- Pricing: Custom pricing (verified )
- License: Paid
- Platforms: web
- Best for: Cold email and marketing teams that need to warm up a new sending domain or repair a damaged sender reputation before scaling outreach volume.
- Standout feature: A 500,000+ real US mailbox seed list combined with an AI co-pilot (Adeline) that reads DNS, warm-up, and Google Postmaster data and tells the sender exactly what to fix.
- Biggest weakness: Pricing is not published on the site; it is volume-based and only disclosed after booking a demo or starting the 7-day trial, which makes it hard to compare costs against competitors upfront.
