Three symptoms we find in every diagnostic. All fixable, once you understand the architecture underneath.
They still run because the product is good. Not because the sequence is. 40% of the potential is left on the table.
No plan, no target segment, no revenue goal. Just "send something this week".
Years of promotions have trained your customers to never buy at full price. It's fixable. But not with one more email.
Your emails aren't a side channel. They're a revenue line.
No phase starts before the previous one is validated. No send goes out without a revenue number attached upfront.
We map what every stage of the customer relationship earns you. We put a number on what you're leaving on the table.
We rebuild the automations that matter: welcome, cart abandonment, post-purchase, win-back, loyalty. Each one with a revenue target attached.
Weekly campaigns, SMS, web push. One plan a month. An expected revenue for every send.
First owned revenue milestone hit. We document it, systemize it, and train your in house team once you have one.
30 minutes live on your account, free and with no strings attached.
A dedicated team. A monthly plan. Clear reporting on what it earns you.

5 days. We analyze your setup and hand you the priorities for the next 6 months. Refunded if we don't find at least 3 points of revenue to go after.
3 weeks. Brevo → Klaviyo (or the other way around). No flow lost, no downtime. You switch tools without losing what you've built.
If the strategic audit doesn't find at least 3 points of revenue to go after, it's refunded.
Charlotte designs your strategy and talks to you directly. No sales layer between you and the expertise.
Every month: what we sent, what it earned. We steer by revenue, not by open rate.
The first meeting is free and non-binding. You walk away with a diagnostic either way.
We fit the lifecycle architecture to your purchase cycle, not the other way around.
Collection cycles, seasonal reactivation, resale.
Predictable repurchase, subscription logic, routine cross-sell.
Automatic reorder, purchase frequency, loyalty program.
High cart value, long cycle, nurturing before the decision.
Community, product storytelling, LTV maximization.
Onboarding, activation, expansion, lifecycle retention.
