About Zettler Digital
Since 2014, we’ve helped 450+ Shopify brands turn first orders into repeat customers, with dedicated specialists for retention on Klaviyo, Shopify and paid media.
We've launched, run and sold ecommerce brands ourselves.
Zettler Digital is a growth agency for Shopify brands, most doing between $1M and $30M a year. Since 2014 we've worked with 450+ brands across North America, Europe and Australia.
Retention, Shopify design and development, and paid media each have their own specialists, and every channel is judged on what it adds to the business, not what its own dashboard claims.
Ben Zettler
Ben founded Zettler Digital in 2014, after starting his own Shopify brand and while leading ecommerce at Steiner Sports. He launched Brooktide Sunglasses in 2013 as Shopify store #41,000 and ran it until it was acquired in 2018. At Steiner, he moved the business from a custom-built site to Shopify and its email program to Klaviyo before Fanatics acquired it in 2019.
Today he leads the agency's strategy and works directly with client teams. He sits on Klaviyo's Partner Advisory Council and has spoken at Klaviyo's company-wide meeting twice: on a panel in March 2025, and in March 2026 in a one-on-one interview with CEO Andrew Bialecki. He also writes for the Klaviyo blog and shares what's working in retention and Shopify with about 15,000 followers on LinkedIn.
Before ecommerce, Ben was assistant director of baseball operations at the University of Maryland, his alma mater. He lives in New Jersey with his wife and children.

"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."
