Zettler Digital
Zettler Digital is an ecommerce growth agency and Klaviyo Master Elite Partner. We've worked with 400+ brands since 2014, from first-time Shopify launches to nine-figure retail businesses. Most agencies treat Klaviyo as a send tool. We treat it as the retention layer of the business. That's the place where customer data, segmentation, lifecycle timing and creative all have to agree with each other before revenue moves. What we do in Klaviyo * Full flow architecture: welcome, browse and cart abandonment, post-purchase, winback, replenishment, VIP and sunset * Campaign strategy and calendar management, including promotional planning around launches and peak season * Advanced segmentation built on purchase behavior, predictive analytics, and custom event data * SMS program build and compliance, including cross-channel coordination so email and SMS aren't competing * Deliverability work: list hygiene, sending reputation, authentication, and re-engagement of lapsed subscribers * Custom integrations and data modeling for subscription, wholesale, and multi-store setups * Ongoing testing programs across subject lines, offers, timing and creative Beyond retention We're also a Shopify Platinum Partner running theme development, CRO and store builds, plus paid media on Meta and Google. That matters because retention performance is capped by what happens on-site and by who's entering the funnel in the first place. When one team owns acquisition, the storefront and the lifecycle program, the feedback loop between them actually closes. How we work Senior-led, no account-manager telephone game. You talk to the people doing the work. We report on revenue, retention and contribution — not open rates in isolation. Engagements are typically monthly retainers, with project-based work available for migrations, audits and rebuilds. Good fit for DTC and omnichannel brands on Shopify or Shopify Plus doing $1M-$100M+, especially those with repeat-purchase potential that isn't being captured, a Klaviyo account that's grown messy over time, or a migration from another ESP. Based in the New York metro area with a remote team, working with brands across North America, Europe and Australia/New Zealand.

Hustler Marketing

Hustler Marketing is an award-winning email marketing agency that helps extend the Lifetime Value of your customers with a complete, Done-For-You email and SMS marketing service. In 2023, we generated $100Mn+ for our clients in email revenue. Each of our eCommerce clients gets a 4-person team who takes full control of their email & SMS channels: * An experienced Account Manager who oversees strategy, reporting and briefing of creatives. * A designer and copywriter who craft engaging, on-brand emails that boost retention revenue. * A technical specialist to ensure optimal integration with your Email Service Provider. We pride ourselves on maintaining the best client-to-manager ratio in the business. Each of our Account Managers takes care of only 2-3 stores, ensuring that they always have the time to give each one the focus it deserves. Most of our clients start seeing growth in open rates, click rates, spam rate reduction, and a marked increase in email revenue within 2-3 months working with us.
