TURN TRAFFIC INTO REPEAT REVENUE.
We turn your email and SMS lists into your
most profitable sales channels.
GRUNT is a lifecycle and retention marketing agency
for DTC and ecommerce brands.
THE MOST PROFITABLE CHANNEL IN ECOMMERCE
Retention marketing has the highest return on investment among all digital marketing channels.
Winning a new customer costs 5 to 25 times more than keeping one you already have. Most brands still put nearly all of their budget into the first order. Email and SMS are how you earn the next one.

Reviews
GRUNT took our email off our plate. They fixed what was broken in our account first, then built everything new on a schedule we never had to chase. It felt like having a retention team in house.
The team at GRUNT is incredibly thorough and constantly working to improve their work. I'd recommend them to any brand that wants a strong team behind their retention marketing.
QUESTIONS
HOW FAST DO WE SEE RESULTS?
The audit lands in 3 days and the highest-impact flows go live within the first 30 days. Those alone typically produce measurable revenue in the first month. Your sign-up forms will also be live within the first week, growing your list.
DO WE NEED KLAVIYO?
We build in Klaviyo. If you're on another platform, we'll tell you in the audit whether moving makes sense.
WHO WRITES AND DESIGNS THE EMAILS?
We do. Strategy, copy, design, build, and reporting, in your brand's voice and look.
DO WE GET A SAY IN WHAT GOES OUT?
Every campaign and flow is approved by you before it sends. Nothing ships without your sign-off.
WHAT ARE THE COSTS?
We operate on a flat monthly retainer based on your channel mix and message volume. Because automations generate revenue immediately and continuously once live, the program is designed to pay for itself within the first quarter, often within 30 to 60 days depending on list maturity. The free audit includes a scoped quote, so you know the exact number before committing to anything.
WHAT IF WE ALREADY HAVE FLOWS RUNNING?
Good. We start from what's working, fix what isn't, and build what's missing.
HOW IS GRUNT DIFFERENT?
We don't stop at email. We are brand founders ourselves. Our team has done design, product development, and web for seven- to eight-figure brands, so we know what growing a brand takes beyond the inbox.
HOW LONG IS THE COMMITMENT?
All plans are month to month. You can adjust or cancel anytime.
