Founder of ZHS Ecom. He writes this knowledge base.
Zach Schieffer is the founder of ZHS Ecom, an email and SMS retention agency for direct-to-consumer brands. He started ZHS after years of building and running lifecycle marketing for ecommerce stores, and he still writes and reviews the guides in this knowledge base.
The ZHS team has built retention programs that generated more than $50 million in sales across 50-plus DTC brands. Every guide here comes out of that work: real Klaviyo builds, real campaign calendars, real deliverability recoveries, and the numbers behind them.
He writes about email and SMS flows, campaign strategy, Klaviyo setup, deliverability, segmentation, and the benchmarks that tell you whether a retention program is actually working.
