We help you boost it.
ODDHouse is a retention marketing agency for DTC/eCom and SaaS companies. We help turn the audience you've already won into revenue that keeps coming.




































What ODD stands for
Every decision traces back to real demand, proven by relentless testing and by actually talking to your customers, one to one. That's the ODD Method.
Email and SMS are just the start. We build and run the whole retention side of your program, because growth lives in retention: the fastest way to grow is to make the most of the acquisition you've already paid for.
We work with your team and treat your business like our own. We'll have the tough conversations when they matter, but mostly we do the heavy lifting so retention is one less thing on your plate, and you're free to run everything else.
One to one, on purpose. It's what sets us apart: we're not just here for the revenue. When people feel genuinely seen and appreciated, they don't just buy again, they become your evangelists. That's a moat competitors can't copy.
The loop that compounds
Talking to your customers isn't a one-off. Every conversation feeds the next round of retention, and the results compound over time.
What we do
Oh, we're excellent at Email & SMS. And then some. Retention is made of many channels, so we build and run the pieces that keep your customers coming back.
Lifecycle campaigns that do far more than batch-and-blast, built to sell without burning the list.
Timely, permission-first texts that respect the inbox and move people to act.
Automations mapped to your real customer journey, working around the clock to bring people back.
Programs that reward your best customers and deepen lifetime value.
Recurring-revenue programs designed around keeping customers, not just winning them.
Zero-party data capture that personalizes from the very first click.
Conversion-focused pages built to match the offer and the audience.
A clear read on what's working, what's leaking, and the plan to fix it.
Who we help
We work with DTC/eCom and SaaS companies, and we own the retention program end-to-end. We're obsessed with making the most of the acquisition you've already paid for, using the channels that actually work for you. Everything is bespoke: you won't get a playbook, you'll get a strategy and program built around your brand.
We do white-label retention work for other agencies when things get busy. We're a reliable partner for the stretches when you're over capacity or when your clients are asking for retention services outside of your current offerings.

Some kind words
Testimonials received as Email Science or ODDHouse.
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.
