“Matt was awesome!!! We spoke on the phone prior to starting the job and went through the work required and I have never had a freelancer be so honest with me on what parts he could do really well and the parts he admitted were a weakness. We set up the job to design a Shopify site from scratch focusing on his strengths and he crushed it. Beyond psyched about the end result and the process was super smooth and his communication was amazing throughout. Literally hiring him again next week for a new project. Thank you Matt”
★★★★★
Marketing Agency Account Manager & Sales Director
“I worked with Matt over the past 2 years. Originally he started working as an account manager/email marketing strategist in our company. After one year, he became one of the best account managers who delivered great work to our clients and achieved high results for them. Due to his high ambitions, he proposed to promote him from the Account manager position to a sales person first and then to the sales director. Since we promoted Matt to sales director, our sales closure rates rose to 33%+. We valued Matt as a team member and as a great person. Thank you for all the dedicated and loyal work.”

How I work
I start with a deep audit and hand you a prioritized roadmap. From there, I can build tailored AI systems around your brand—not generic templates.
01
I run a deep diagnostic of your flows, segmentation, and deliverability, pinpointing what's underperforming and what it's costing you in revenue.
02
I turn the audit into a prioritized, actionable plan: what to fix first, what to build next, and the projected impact, including advanced segmentation and A/B testing strategy.
03
I build tailored AI-powered systems that run your email marketing — automating segmentation, content, and flow logic around your brand. Includes custom integrations for tools Klaviyo doesn't support natively.
FAQ
No. I'm not a full-service agency, and I don't pretend to be. I build you the strategy, the automation, and the systems so you can run it better — and more affordably — than handing the keys to an agency.
A free call, then a deep audit of your Klaviyo account. You get a prioritized roadmap of what's costing you revenue. From there we decide what I build.
Often, yes. A lot of brands already have someone sending campaigns and still have leaks in flows, segmentation, and deliverability. The audit makes that visible before anyone commits to more work.
Tampa, Florida. I work with DTC Shopify brands wherever they are.

I looked at roughly 2,000 US Shopify storefronts. Double opt-in is common. Gating the discount behind a confirmation email is not. That setup is present on about 1 in 6 stores I checked, and it's costing them revenue.
