“As a founder, partnering with agencies has at times felt like one endless game of musical chairs. You end up cycling through many that don't meet your expectations. Duh Retention has been different - practical, cost-effective, sound thought partners that adapt well to feedback. They've become an integral piece of our profitability formula.”
Buffy • Leo Wang, CEO
“Duh Retention’s true value comes from how they approach Retention marketing. No buzzwords, no fancy/complicated strategies… They’re straight shooters who know how to increase the value of your customers. The Duh team is thoughtful & reliably execute on what they say they’re going to do – I never have to second guess them.
If you’re looking for Retention experts who drive real results then you’ve gotta work with them.”

We’re not perfect. But there are a few things we do exceptionally well.
holistic strategy
Unlike most Retention marketers, we’re not siloed to email/SMS. With backgrounds in paid media, CRO, and brand building, we know what levers to pull on the retention side to drive business-wide results.
Lean & Long-term
We’re a lean team with a lean client-base... And we like it that way. We only partner with serious, growing brands who aren’t pressured to make shortsighted decisions. This ensures we can build you a world-class lifecycle program.
over 80+ emails sent
That’s a lot of reps with a lot of learnings. We’re solely focused on increasing the value of every customer that walks through your door. And we’ll do it in any – and every – way we know how.
