ODDHouse is a retention marketing agency. We help you get your customers to come back to unlock sustainable, compounding growth.
The real problem
Winning a customer is just the beginning. The hard part is getting them to come back, and that is where your real, compounding growth lives. So how do you turn that first order into a second, and a third? That is exactly what a retention program is built to do.
Retention is the lever that makes your acquisition pay off.
What ODD stands for
Every decision traces back to real demand, with retention as the core. That's the ODD Method. When was the last time your agency actually talked to your best customers?
Our not so secret sauce
Anyone can say they love your brand. Far fewer back it with their wallet, again and again. These repeat buyers are your North Star. What they tell us, combined with your data, shapes our retention marketing strategy, because the people already paying you and supporting you are the ones who can tell you exactly how to earn the next sale.
The rest is all in how we work.
We dig into your data and get to know your business inside out. Everything we do is driven by what the numbers actually show, not by guesswork.
Every test starts with a hypothesis and a metric we want to improve. We don't test for the sake of it, we test to learn what moves the needle, then scale what works.
Wherever it makes sense, we find the natural moment to bring a customer back and build it in. Never forced into everything, just placed with intention where it serves your customer.
The loop that compounds
Talking to your best customers isn't a one-off. We listen, read the data, test intentionally, and build retention in wherever it makes sense. Every round feeds the next, so real growth compounds instead of starting over each time.
What we do
Retention runs on many channels, not one. We build and run every piece that brings customers back and keeps them buying, so the whole program compounds instead of leaking.
Lifecycle campaigns and automated flows, mapped to your real customer journey and built to sell without burning the list.
Timely, permission-first texts that respect the inbox and move people to act.
Physical touchpoints that cut through a crowded inbox and bring high-value customers back, timed to the moments that matter.
Programs that reward your best customers and deepen lifetime value.
Recurring-revenue programs, subscriptions and memberships, built around keeping customers, not just winning them.
Zero-party data capture that personalizes from the very first click.
Pages built to match your emails, so the journey from inbox to click to purchase feels like one cohesive experience.
A robust testing program across your campaigns and flows, so we can keep optimizing for both conversion and retention.

Working with Kat has been simply wonderful. We worked on two projects together [Tricerapro and The T.J. Martell Foundation]. She's smart. Responsive. Dedicated and proactive. When it came to our email marketing, I knew with Kat I was in good hands and could focus on the other work that needed to be done. I will absolutely work with her again.
Working with Kat was wonderful from start to finish. She knows email marketing inside and out, and could quickly identify areas for long-term impact and map out a smart plan forward. Kat was truly always one step ahead, bringing thoughtful ideas, and spotting opportunities we hadn't considered. Proactive, collaborative, and genuinely so easy to work with. I'd recommend her in a heartbeat to any client or agency.
Working with Kat has been one of the best decisions I've made for NaturalAnnie Essentials. I started working with Kat at a pivotal point in my company and she has truly helped me achieve our email marketing goals. From day one, she was incredibly reliable, patient, and deeply knowledgeable. She didn't just manage my email marketing, she transformed it. I can't recommend her highly enough.
