Two email technology firms, Warmy.io and Woodpecker.co, have formed a strategic partnership to drive cold email automation.

The arrangement combines Warmy’s AI-driven domain reputation engine with Woodpecker’s campaign management suite.

The goal is to unite “two ends of the spectrum: the power to send and the reliability to land,” says Daniel Shnaider, co-founder and CEO of Warmy.io, in a statement.

The firms are attempting to solve a persistent pain point: ensuring that high-volume outbound sequences actually reach the recipient’s primary inbox.

"Email remains the most critical sales channel, yet billions in potential revenue are lost to technological barriers," Shnaider says.

Woodpecker provides the infrastructure for personalized sales conversations, while Warmy provides the underlying security that these conversations take place.

Warmy.io, which describes itself as a profitable bootstrap company, analyzes data from tens of millions of daily emails, to identify deliverability trends that ensure users maintain a pristine sender reputation at scale, it says. It has more than 100 employees in 14 countries.

We assume that “cold email” is permission-based. 

Warmy.io recommends that new email senders start slowly with a domain warmup.

“As the first emails are received and opened, the likelihood that subsequent campaigns will land in the primary inbox increases,” Shnaider has said. “Avoiding a sharp spike in activity also protects against the danger of being added to international blacklists—a situation that can require a long and complex recovery process.”
