Email Operators Who Actually Ship

Our retention operators pass practical Klaviyo tests before placement. They build real flows, convert real designs, and execute real QA checklists — not just answer interview questions.

Every operator completes our StackCertified AI proficiency program — trained in AI-assisted email copy, subject line optimization, and segmentation strategies using tools like ChatGPT, Claude, and automation platforms.
