"When I sent Zettler Digital a merchant dealing with a sudden spike in deliverability issues, they had a clear plan ready in under 24 hours. They've seen just about every inbox problem, and that's what I look for in a partner: a team ready to step in and roll up their sleeves."

"Zettler Digital understands that smart retention is about sending to the right people, not just sending more. They're one of the sharpest Klaviyo partners we work with, and their clients see the full benefit of Orita because the strategy around it is just as strong."

"Zettler Digital is one of the most innovative agencies in lifecycle marketing and retention.
