Warmy
Warmy is an email deliverability tool that warms up domains and mailboxes, tests inbox placement and monitors sender reputation, for cold outreach teams, agencies and marketing senders.
Updated October 2026
Overview: What is Warmy?
Pricing is based on warmup volume and quoted after a demo, with a 7-day free trial and no credit card (checked October 2026).
It sends personalized warmup emails to a network of real mailboxes that open, reply and pull messages out of spam, and you can choose a business network (Google Workspace and Microsoft 365) or a consumer one (Gmail, Yahoo and Outlook). It also pulls Google Postmaster data, checks DNS records and blacklists, and offers seed lists for testing where a real campaign lands. Warmy was founded in 2020.
Fit: Ideal customer profile.
Teams sending cold or marketing email from new or recovering domains who want warmup, placement tests and reputation monitoring in one place. Agencies managing dozens of domains should check API access first, since one independent review notes bulk domain management still happens mostly in the interface.
