What is Warmy?
Warmy.io is an email deliverability platform. It automatically warms up your mailbox by simulating natural send-and-engage activity, monitors your sender reputation and placement, and provides tools and a deliverability score so more of your cold and marketing emails reach the primary inbox instead of spam.
Warmy pricing (2026)
Warmy plans start around $49/mo per inbox, scaling up by warmup volume and the number of mailboxes, with higher tiers for teams and agencies. A free trial lets you measure placement gains before committing, and annual billing lowers the rate. Confirm current pricing on Warmy.
