Engagement
The challenge
Cookie banners and bot traffic left big gaps in Shopify's tracking, so channel numbers looked very different year over year even though the sales were real.
What I did
- Explained to the client why Shopify's attributed revenue dropped without sales dropping
- Compared Shopify, ad platforms, Triple Whale, Klaviyo and Hiro instead of trusting one report
- Ran paid media, email and SMS against one daily flash report on GMV, spend and pacing
Attribution changed. We kept hitting monthly GMV goals.

Questions brands actually ask.
If yours isn't here, send a note and I'll answer directly.
What does a retention marketing consultant do?
I own the part of your marketing that happens after the first order: email, SMS, lifecycle flows, segmentation, and the reporting that shows whether customers come back. Depending on the engagement, I audit, build, or run the program alongside your team, agency, or freelancers.
What size brand do you work with?
Most of my clients are CPG and DTC brands doing roughly $5M to $100M a year. Below about $1M there usually isn't enough customer data to justify senior retention work, and I'll tell you so on the first call.
Why hire a consultant instead of a retention agency?
With me, the person who scopes the work is the person who does it. Agencies are a good fit when you need a large production team. I'm a better fit when you need senior judgment, a program built right, and someone who connects retention to your paid media and your numbers.
Do you work directly with brands or through agencies?
Both. I work directly with brands, and I've also been the senior retention lead inside agency and growth teams. If you're an agency with a client who needs lifecycle strategy, let's talk.
What's included in a Retention Audit?
A review of your Klaviyo account, flows, campaigns, segmentation, SMS, deliverability, list health, and integrations, measured against your revenue goals. You get a ranked list of fixes with effort estimates and a walkthrough call, in two to three weeks.
Do you only work in Klaviyo?
Klaviyo is where I spend most of my time, and I'm Klaviyo Product Certified. I've also worked with Shopify, ReCharge, Skio, Stay.ai, Yotpo, Okendo, and HubSpot, and I've moved programs between platforms.
Do you manage paid media too?
I plan and direct it: channel mix, budget recommendations, forecasts, and performance reviews, working with whoever runs the ad accounts. Retention is my focus. Paid planning is how I make sure the customers you buy are worth keeping.
Do you work with subscription brands?
Yes. Subscription and replenishment brands are a big part of my work, and I've worked in ReCharge, Skio, and Stay.ai alongside Klaviyo.
How is pricing structured?
The Retention Audit is a fixed fee. Builds are scoped as fixed projects, and ongoing work is a monthly retainer. We'll size it on a 30-minute call.
