Reloop Domain Age & Warmup Checker

Reloop Domain Age & Warmup Checker is a free, fast, and easy-to-use tool designed to help email marketers, founders, and developers assess the readiness of their domains for cold outreach. By simply entering any domain or URL, users receive detailed insights into the domain's exact age, registration and expiry dates, and the current warmup stage—ranging from Too New to Established. This information is crucial because domain age significantly impacts email deliverability, with newer domains often at higher risk of landing in spam folders. What sets this tool apart is its speed (results in just 2 seconds), zero sign-up requirement, and open-source foundation, making it accessible and trustworthy for users concerned about their email infrastructure. Built by Reloop, a company committed to transparent, open-source email solutions, it provides a practical way to gauge deliverability risks and optimize cold email campaigns efficiently.
