You've already figured out the problem yourself.
Your ads work.
Every day those ads run, your list gets bigger. People who raised their hand, gave you their email, and then (mostly) went quiet.
And you know that list should be producing more than it is.
So you've tried to fix it. Maybe a freelancer, who needed so much review time you'd have been faster writing it yourself.
Maybe an agency, who sent you a content calendar and asked what you wanted to promote next month, which is a strange question coming from the people you hired to know that.
Maybe you just did it yourself for a while, three campaigns a month, each one written at 11pm in the free time between everything else.
The standard agency model is built to give you homework. One strategist spread across 40 accounts won't ever know your customer as well as you do.
So every brief, every campaign idea, every "what's the angle this month" gets routed back to you...
#klaviyo-slack-killmepls0Caleb runs a brand doing eight figures. Before us, he'd tried contractors. His words:

That's a founder refusing to let mediocre work go out under his name. Fair.
Look at why each attempt failed:
Look at how many accounts each one was carrying:
Three of those are the same picture: one person carrying too much.
It's a structural problem.
The fourth is the only structure where no single person is the bottleneck. And it's the only option that caps how many accounts it takes on, so your account actually gets attention.
That structure has a solution.
We install a five-person email department inside your business, and it runs on one hour of your week. Here's everything in it.
The same five people taking care of your Klaviyo every week. Our pods runs six Klaviyo accounts maximum.
We don't oversell capacity, so your brand can get the attention it deserves.
For scale: one senior in-house email hire runs about $11,600/mo after benefits. They only have one skill set, plus a new direct report for you to manage.
Before we send email one, we build the strategy: avatar research from real customer language, awareness mapping of your list, the macro and micro campaign architecture for your next quarter.



"I'd tried three of these before. this is the first one I actually finished."

"honestly the price made me wait six months. wish I hadn't."


"bought it for my back. kept it for the sleep."
$7,500 of strategy work, included.
This is the strategy work your past freelancers and agencies dumped back on you.
Your first campaign drafts ready 36 hours after our kickoff call
Stephen came to us already burned by an agency that never learned his brand, and less than 36 hours after signing, he was reading drafts:

You'll get a Slack notification with next two weeks of campaigns, waiting on your thumbs-up.
Our customer approval app opens up. You read the emails and they sound like your brand. You click "approved" and go back to whatever you were actually doing.


Quarterly audits, engagement-based sending, inbox placement tracked as a managed metric instead of discovered as a crisis. $1,500 a month of specialist work, included.
We're a Klaviyo Gold Partner, which matters exactly here and almost nowhere else: a badge never ensured a good email, but it means the technical deliverability behind your email revenue is run by people Klaviyo vouches for.
The most important number in that screenshot isn't the obvious good one. The click rate sits below the peer median. The conversion rate is 3.3x it. Most agencies would crop that first row out. It's our favorite row on the page.
When the email does the selling before the click, fewer people click, but the ones who click have already decided. Clicks go down, conversion rates go up.
Our complete flow system – six core flows, 23 emails, from welcome to winback – installed during onboarding, selling around the clock underneath everything the campaigns do. Every flow, every email, mapped below.
We charge $9,500 for this on its own. Retainer clients get it included, because sending campaigns over broken flows is pouring water into a cracked glass.
Every week, we go into your support inbox and mine it for gold:
Recurring objections, the exact phrases customers use when they hesitate, the questions that show up right before someone buys or right after they don't. That language gets routed straight into your email copy, and the product insights get routed back to you.

This is where the emails come from, in case you were going to ask. Not "Really Good Emails" or "competitive research" or a swipe file. But your actual customers.
Conviction-building copy begins with customer-understanding systems.
The exact number depends on send volume and the size of your list — we scope it on the call
If you're spending what most of our clients spend on ads, it's less than two days of ad budget, pointed at the only channel where the traffic is already paid for.
But the honest comparison isn't to other line items. It's to your hour.
A founder or CMO running a brand your size is worth $500 to $1,000 an hour, and email done properly eats 15 to 20 of those hours a month. You can keep spending them, or you can spend one.
If campaigns aren't generating at least 8x the retainer in attributable revenue by day 90, you stop paying until it is.
The second guarantee backs up the first one. No lock-in, no 12-month commitment, no exit clause to lawyer through. You can leave whenever by giving us a 14-day heads-up.
Our average client stays eighteen months.
We have no contract to trap you, and clients stay anyway.
We run pods with five people each, six accounts each and then the pod is closed. The cap sustains quality.
A seat opens when an account leaves a pod.
Given the eighteen-month average, that's not often.
Brands that are already winning: proven product, working ads, $3M to $30M, a founder or marketing lead who can make a decision without summoning a committee. Email here is fuel on a fire that's already burning.
Brands where every email needs four stakeholders' approval. Good emails require good ideas. And those normally get dilluted to the average (the "safe") through committees.
What's next:
In a 30-minute call we'll look at your list, your flows, and your last 90 days of campaigns. The math normally works. In the case it doesn't, we'll tell you that too. The guarantee makes us honest about who we take.
Five people, organized around your brand. First drafts in 36 hours. Four campaigns a week, minimum, each one aimed at a segment. Your high-converting 23-email flow setup built free. Your customers mined weekly for the words that sell them. One hour of your week , and if email isn't doing 8x the retainer by day 90, you don't pay until it is.
You built the brand. You bought the traffic. The list is sitting there.
One hour a week.
