We help £50k-£300k/mo brands turn one-time buyers into predictable cashflow - without burning your list on discounts or relying on juniors learning on your account.
“People who deliver like you have are a rare breed. After six years working with suppliers, I can say that without a doubt.”
































CAC is up. Margins are tighter. You know repeat customers are how you survive.
But here's what's actually happening right now:
Your first-time buyers aren't getting the right message at the right time - or any message that matters. Your flows are generic. Your campaigns have no system. Discounts are the only lever that works.
When we audit brands after their previous agency, we find the same leaks:
Revenue falling out of broken post-purchase journeys. Disengaged lists from over-messaging. Campaigns gobbling flow revenue because no one's watching. LTV:CAC ratios getting worse, not better.
This isn't a channel problem. It's a systems problem.
And it compounds every month you don't fix it.
| Typical Agency | Crag | |
|---|---|---|
| Who does the work | Junior account managers learning on your business | 20+ combined years, senior operators only |
| What they know | "Best practice" templates copy-pasted across 50 brands | Custom systems built for your business, not templates |
| How they measure | Activity (emails sent!) not outcomes (profit) | Profit impact: LTV, repeat rate, cashflow |
| Strategy vs execution | Strategy decks that never get implemented properly | Same people who strategise also implement and optimise |
| After onboarding | Disappear, hand you off to juniors | We tell you when something won't work or you're not ready |
We're small by design. We take on 4-6 brands per quarter so senior people stay involved and things don't drift.
No hand-offs. No juniors. No bullshit.
You've proven product-market fit. You're acquiring customers. But LTV isn't keeping pace with CAC, and retention feels like it "exists" without actually contributing to profit.
Free. 30 minutes. No commitment.
Most teams jump straight to tactics: new flows, more campaigns, better copy. That's why it doesn't work. The problem isn't what you're sending. It's that the system underneath is broken.
Audit data hygiene, deliverability, list health, capture mechanisms, and lifecycle coverage. Fix what's quietly killing performance before building anything new.
Map the lifecycle, identify where revenue should come from but isn't, and decide the order of work. Short roadmap tied to reality - not a wishlist.
Flows rebuilt. Campaigns planned with intent. Email and SMS working as one system, not fighting each other. Work staged deliberately so nothing collides.
Optimise based on what's driving profit, LTV, and cashflow - not vanity metrics or "best practices" that don't apply to your business.
This structure avoids the most common failures: building before priorities are clear, campaigns without purpose, too many ideas at once, activity without outcomes.
We build systems that compound - not campaigns that burn out.
"We've tried a couple dozen service providers... not one has ever delivered anything valuable enough to keep working with them. Finding a provider who genuinely provides a return is like hen's teeth - these guys have proved themselves."
"Since we've been working with Crag, our email marketing revenue is up over 135%. Email as a total of Shopify revenue is 35%. Aside from the numbers, Crag Marketing really understands the brand, making it super easy on a day-to-day basis. I couldn't be happier with Crag Marketing."
"Crag has become my best ROI in terms of spend for the brand... 40% of our Shopify revenue coming from email. The best part is it's become effortless."
"They take the time to really understand your business. They get under the skin of it. They come to you with new ideas and different suggestions - sometimes even taking you in a direction you hadn't originally considered - and that's hugely valuable. It goes far beyond a typical client-agency relationship."
These aren't tactics. They're outcomes of doing the fundamentals in the right order.
Book Your Revenue Leak Audit →This isn't a sales call. It's a structured review of your retention infrastructure to answer one question: Is retention actually worth fixing in your business right now - and if so, what would that realistically involve?
We implement it with you (3-month sprint).
Here's what needs fixing first (we'll tell you how).
Here's exactly why and what to do instead.
Sometimes the answer is "yes, let's go." Sometimes it's "not yet." Either way, you get clarity.
No long contracts. We don't pretend everything is "a great fit."
We help £50k-£300k/mo brands:
Capture mechanisms and offers that actually convert high-intent visitors.
Sequences that drive repeat purchases without burning trust.
Strategic sends based on behaviour and tied to business goals - not arbitrary calendars.
Email, SMS, and loyalty working together - not fighting each other or over-messaging.
Target customers in ways that affect cashflow and LTV - not just engagement.
Profit impact, repeat purchase rate, LTV:CAC - not vanity metrics.
All of this sits inside one system. We don't offer it à la carte.
Retention channels aren't the goal - they're the infrastructure. The goal is predictable profit from customers who buy again without needing a discount to do it.
Between us, 20+ years inside DTC brands building retention systems that actually drive profit - not just activity.
We started Crag because we kept seeing the same pattern: brands spending money on retention that didn't work. Not because the channel was broken, but because the system was never built properly.
We're small by design. Senior-only by default. Limited brands at a time.
If you're looking for cheap retainers, endless experiments, or someone to tell you everything's fine - you'll hate working with us.
If you want retention to become a reliable, predictable profit channel - not a constant source of frustration:
