Woodpecker

Woodpecker is the cold email outreach platform Maciej Cieśla and Matt Piorkowski bootstrapped from Wrocław, Poland in 2015. It automates personalized cold email sequences for sales teams and agencies, with a focus on deliverability and safety: Woodpecker limits daily send volumes automatically, adds human-like sending delays, detects and stops sequences when a reply is received, and monitors bounce rates to protect the sender's email reputation. The platform grew to $5M+ ARR with 60+ employees by serving agencies running outbound campaigns for multiple clients and B2B SaaS companies building outbound sales pipelines. Woodpecker's agency mode — managing multiple client campaigns from one account with separate inboxes and separate reporting — became its defining feature for the agency market. The team conditions feature (auto-stop a sequence if the prospect opens the email more than 3 times without clicking, or if they visit the website via a tracking pixel) allowed sophisticated behavioral triggering without requiring a full marketing automation suite.
