Retention Harbor
We focus on building high performance retention systems through our proprietary Revenue Anchor system. We meet you and your team where you are. Some brands want us to run the full retention program.

The Revenue Anchor process gives you a proven foundation for growth while letting you choose the level of involvement you want from us. We’ve worked with 20+ ecommerce brands, including several doing over $50M a year. We're experts at understanding your customers and building a retention program that matches how people actually buy from your brand. We’re capable of handling all parts of the retention stack including flow rebuilds, campaign management, deep segmentation, high converting popups, zero party data collection and usage, subscription specific flows, subscription program setup and consulting, custom coded solutions, and ESP migrations to Klaviyo. If you want to see what working together would look like, we offer a free account audit and a set of sample email designs so you can get a clear feel for our service.

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.

We will do all the work to match you with the best partners.

Meet our team, your partner matchmaker.

We are retention experts and strategists. We have built and sold DTC businesses. We are determined to increase LTV’s, improve purchase rates, and drive profitability. While our core focus is email, SMS, and pop-ups…we have a deep understanding of the full tech stack when it comes to lifecycle marketing.

Every ecommerce brand is at a different stage. Some of you are doing your first $50K months and figuring out flows for the first time. Some are past seven figures and ready to layer in SMS, CRO, and paid social. Some just migrated to Klaviyo and need someone to actually build it out properly. We meet you where you are. AskTimmy is a Klaviyo Gold Partner running full retention for 25+ small and medium DTC brands across the US, UK, Canada, and Australia — email, SMS, CRO, and Meta Ads under one roof. These are the brands we love working with. Founder-led, still hungry, still building. The kind where every campaign, every flow, every ad we ship actually moves the number. What you get with us: * A real partner, not a vendor. We learn your brand, your voice, and your customer. Then we build like it's our own store. * Retention-first thinking. Your existing customers are your cheapest revenue. We build flows and segmentation that keep them coming back. * Full-stack under one roof. Email, SMS, CRO, and Meta Ads all rowing in the same direction — because your welcome flow and your retargeting ad should be telling the same story. * Senior team on every account. You work directly with strategists, designers, and copywriters who've lived in Klaviyo for years. No junior handoffs. * Month-to-month. Pause anytime. No long-term contracts.
