The problem

If your email list isn't driving at least 40% of your revenue, you're leaving profit on the table.

Most stores treat email like an afterthought. Last-minute campaigns, broken flows, and generic designs that don't reflect the brand. What you end up with is a noisy inbox presence, not a revenue machine. Email and SMS should be your most profitable channel, not a source of stress, missed opportunity, or guesswork.

01

Weak or missing flows

Only a basic welcome and abandoned cart? You're missing 80% of what drives revenue.

02

Inconsistent campaigns

No strategy, no rhythm, just occasional discounts that train your list to ignore you.

03

Off-brand design and copy

Templates that clash with your aesthetic, copy that sounds like everyone else.

04

No visibility into results

Can't tell what's working or what's wasted? You're flying blind without proper reporting and testing.

That's exactly what we fix.

FAQ

Frequently asked questions.

How fast can we get started? +
Once your invoice is paid, the onboarding form is submitted, and our Klaviyo access is set up, we typically begin your audit and roadmap within 1 to 3 days.
What platforms do you work with? +
Klaviyo is our home base and the platform we recommend because of its powerful features and accurate reporting. Most of our clients either already use Klaviyo or switch to it with us. We can also work alongside other tools in your stack, for example using Klaviyo for email while you use different software for SMS or popups.
What's your pricing model? +
We charge a flat monthly retainer between $3,000 and $5,000 per month. If your brand is doing above $100K per month in total revenue, we can also work on a revenue share basis. No hidden fees, no random hourly charges. You always know exactly what you're paying for.
Do I need to provide copy or assets? +
We handle strategy, copy, design, and sending start to finish. All we need from you is basic media like product photos or UGC. Nothing fancy. We can enhance and scale your content using AI and proven creative systems.
What kind of flows can you develop for me? +
Anything you can think of inside Klaviyo, from welcome, post-purchase, and winback to complex behavior-based or VIP flows. As long as we understand the goal and logic, we can build it. No external developer required.
Is there a minimum commitment required? +
Nope. Our service runs month to month with no long-term lock-in. If you're loving the results, we do offer 10% off with a 6-month agreement.
Can you work with my existing team or designer? +
Yes. We can collaborate directly with your creative or marketing team, or run things 100% independently. Whatever fits your workflow best.
Can I hire you for one-time projects? +
Yes. Whether it's a template build, a flow setup, or troubleshooting something technical in Klaviyo, we offer one-off services too. Just book a call and we'll match you to the right solution.
