Lifecycle Marketing & Marketing Operations

Lifecycle Marketing That Fixes What's Breaking.

Most teams don't have a lifecycle problem because they don't care about retention. They have one because lifecycle gets pushed down the list when priorities shift. Flows stop being optimized. Segmentation gets messy. Attribution becomes unclear. I come in, find where it's breaking, and fix it.

Most lifecycle problems aren't caused by lack of effort.

They're caused by systems that were built once and never revisited. Flows that made sense two years ago but don't reflect how customers actually behave now. Segmentation that's too broad to be useful. Attribution that nobody trusts. Customer data that exists but isn't driving decisions.

That's not a technology problem. It's an operations problem. And it has a fix.

My background sits at the intersection of lifecycle strategy, marketing ops, and conversion.

I'm comfortable jumping into existing systems, reading the data, and identifying where performance is breaking. I don't need hand-holding to get oriented. I've managed 100K+ contact databases, led marketing operations for multi-location organizations, and built lifecycle programs that connect customer behavior to measurable revenue.

I understand the infrastructure side and the customer psychology side. Both matter. You can't build a lifecycle system that performs if you only know one of them.

What I'm Hired to Fix

The Engine

Email & Retention Strategy

I take over your Klaviyo completely. Flows rebuilt from behavioral logic. Campaigns segmented by purchase behavior. Copy written for your customer, not a template. You review and approve. That's it. Starting at $1,500/month.

The Dashboard

Measurement & Attribution

You can't optimize what you can't see. I build the attribution layer so you know exactly what email is generating and where the gaps are. GA4, CRM, the full picture. $3,000–$6,000 project.

Fractional Leadership

Lifecycle Strategy & Oversight

Marketing is getting attention but not generating the revenue it should. I step in as fractional lifecycle lead: owning strategy, managing execution, connecting marketing activity to business outcomes. Starting at $4,000/month.

Results. Not promises.

Lifecycle program rebuilt from the ground up. 8 months.

What People Say

“I've worked with Stephanie for years, first as her manager, and later as a client. What's stood out from day one is how she thinks: big picture, strategy-first, always connecting the dots between the work and the goal. If you get the chance to work with her, take it.”

JeriLynn ThorpeFounder, Current Marketing

“Her attention to detail and willingness to push our brand is always helpful. One on one advice and never makes us feel silly for asking questions. She makes it look so easy when we know it isn't.”

Kayla PradoOwner, Kareful Adventures

If your lifecycle is underperforming, I can tell you why.

Most teams already know something is off. They just don't have someone with the time and expertise to find exactly where it's breaking.
