How we "make you more money with emails"
A Smooth, Structured Approach That Takes You from Concept to Execution
1
Auditing and Onboarding
The very first thing we must do before we start anything is auditing your current account.
We thoroughly assess your existing email data to develop a strategic plan with clear KPIs and defined timelines for when we expect to hit those goals.
Onboarding is quick and seamless — once we sign, I immediatley book a call and I'm usually in town within the first 72 hours and walk you through your account audit.

Account Kick Off - The Core 4
Unlike most agencies that focus only on setting up flows before thinking about campaigns, we take a more strategic approach to drive results quickly and efficiently.
We kick things off by attemtping to maximize the absolute amount of traffic that your emails are getting in order to maximize the absolute amount your current emails will make. We do this by optimizing for the first 2 of The Core 4 - list growth and deliverability.
After we maximize the absolute amount of traffic your emails are getting, can begin to optimize the latter of The Core 4 - flow and campaign preformance. We launch the Welcome Flow first, since it's typically the highest-converting. This allows us to start generating revenue right away and get you a fast ROI. Once the Welcome Flow is in place, we build out the rest of your core flows around it. With the flows fully set up and optimized, we then shift gears to focus on campaigns.

Long term growth and optimization
Once the account is in a solid position, we double down on growth by consistently delivering fresh, high-quality content. More importantly, we aggressively split test your flows.
From subject lines to timing to content variations, we test every element to uncover what truly performs best for YOUR brand. This data-driven approach ensures continuous improvement and long-term results that compound over time.

Questions

Will I be assigned some random email marketer from Fiverr with bad English?
No way. All of our strategists are native English speakers, hired as full-time team members and trained through our in-house systems. We never poach from other agencies or rely on outsourced recruiters (it's really really hard to break the bad habits they could bring over) — we build our talent from the ground up to align perfectly with our standards.
How do I know that you guys will get me results (aka make me money)?
We've built our approach around proven strategies that consistently drive results for e-commerce brands. Our process is rooted in data-driven decision-making, deep understanding of consumer behavior, and constant testing to find what works best for your unique audience. On top of that, we have team members who have studied psychology meaning we know what you're customers are thinking before they even think about thinking it. We're happy to walk you through our methodology and show you real examples of what we've created so far. So long story short, yes, we'll make you money.
Do you guys have long contracts?
Nope. We don't lock you into 90-day minimums, 6-month terms, or yearly commitments. We know cash flow is critical for e-com brands (even agencies like us), so we keep things flexible. All we ask is a simple 30-day notice if you ever decide to part ways — just like you'd give with an employee. We also ask for an optional but much appreciated Offboarding Call.
Will email/ SMS marketing 100% work for me?
If it's the right fit, yes. And if it's not, we'll be upfront and explain exactly why. We're transparent about what works and what doesn't for your specific situation.
Do you guys offer guarantees?
Not anymore. Here's why: we have so much proof of success that it's unreasonable to expect failure. PLUS, every brand is different. Results vary across DTC verticals, so blanket guarantees don't make sense. What we do promise is this: if we're not 110% confident in delivering ROI, we won't take you on. In fact, we turn away clients every month for that exact reason.
