What is Warmy?
Warmy is an email deliverability platform. Its main job is warming up domains and IPs so they land in the inbox and stay out of spam. It does this with a network of over 1 million mailboxes from major providers and a rotating seed list of more than 500,000 US mailboxes, which open your emails, reply to them and move them out of spam.
Around the warm-up, Warmy adds placement tests, domain and IP reputation tracking, Google Postmaster data, email verification, DMARC monitoring and a template optimizer. An AI co-pilot called Adeline explains the reports. Gmail, Outlook, SMTP and more than 220 sending platforms can be connected, and an API supports custom workflows.
Warmy has separate tracks for B2B senders (Google Workspace, Microsoft 365) and B2C senders (Gmail, Yahoo, Outlook). It is aimed at cold email teams, agencies, eCommerce brands and high-volume senders.
