General information

Warmy is an email deliverability platform designed to help businesses improve their chances of reaching the inbox. It focuses on building and maintaining a healthy sender reputation through automated email warm-up, monitoring, and testing. For companies that depend on cold outreach, sales campaigns, or marketing emails, this can make a real difference to how effectively they communicate with their audience.


Its automated warm-up feature gradually increases email activity and generates positive engagement signals, helping new or inactive mailboxes establish a more reliable sending reputation with providers such as Gmail, Outlook, and Yahoo. You can also run inbox placement tests to see whether your messages reach the inbox, promotions tab, or spam folder before launching a campaign.


Warmy offers several additional tools to support email performance. These include email verification to identify invalid or risky addresses, DMARC monitoring to keep domain authentication in check, and an email seed list for testing campaign placement across different providers. Google Postmaster integration provides further insight into Gmail reputation and spam rates.


Another useful feature is Adeline, Warmy’s AI deliverability assistant. It helps you understand performance data, investigate potential problems, and identify practical ways to improve your email setup. The platform also supports more than 220 email providers and sending platforms, including Gmail, Microsoft 365, SendGrid, Mailgun, Amazon SES, HubSpot, and Klaviyo.
