The Email Marketers
Growing your brand demands powerful email & SMS marketing, but finding the right team for the job? Not the easiest task. You probably already know this... Hiring in-house is costly and time-consuming, freelancers only offer pieces of the puzzle. And most agencies? They spread themselves thin and deliver mediocre results. This is where The Email Marketers come in. We're your top-tier strategic partners on all things retention marketing: Email, SMS, direct mail, subscriptions, memberships, referral & loyalty programs, and more. We're obsessed with your brand's success – the kind of obsession most agencies lack. We are about more than just pretty emails. Our AI-driven data insights and strategies transform your customer relationships to maximize customer lifetime value, delivering the ROI growth-focused companies demand. We are very experienced working with relentlessly results focused brands, very frequently VC funded or private equity backed. While we work with brands of all sizes, our sweet spot is the 8-figure range. Email and SMS are where your customers fall in love – with your brand, your community, not just the product. It's where they become raving fans, even when their initial purchase is done. Our vision is to be the undisputed leader in retention marketing. Our mission? To deliver a wow-experience by increasing your revenue, and forging a community of raving fans for your brand. Curious about how good we really are? Schedule a call and let’s review your account together.

THE MARKETING HOURGLASS Every engagement runs on our published framework. Funnels end at the first purchase; the Hourglass treats it as the middle of the journey, with eight stages from Know to Advocate and equal architecture on both sides of the sale. It has reached over a million marketers, ships as a book, and is why client revenue compounds after order one. DIAGNOSIS BEFORE SPEND We never add flows, sends, or budget before we know where revenue leaks. Our audit scores 13 standard flows against peer-median benchmarks, maps deliverability and technical health, and catches the most common failure in mature accounts: routing fragmentation, multiple welcome, cart, and browse flows competing for the same customer. You get the revenue gap quantified, a conservative-to-opportunistic projection, and a 12-month roadmap sequenced by impact. PROGRESSIVE PERSONALISATION Personalisation should deepen with every order, not stay a static segment-and-send. Zero-party data personalises from day one. Architecture follows order-count economics: roughly 70% of churn happens between orders one and three, so early buyers get habit-forming journeys while proven customers get AOV expansion, VIP treatment, and custom scoring that routes the top 40% of customers to a human, every time. AI-OPERATED DELIVERY Diagnostics, custom RFM models, and cohort analysis run through Klaviyo MCP and Claude: senior-strategist judgement applied to your full account data at a depth manual agencies cannot reach. We have run Salesforce Marketing Cloud, Iterable, and Ometria at enterprise scale; we centre on Klaviyo because that is where the customer record lives. NUMBERS THAT SURVIVE FINANCE Everything we report is last-click, 7-day attribution. On one enterprise audit we corrected our own channel's reporting from ~$806K to ~$194K a month and rebuilt on real numbers. If the numbers are real, the budget survives. RESULTS Pulsetto: $300K to $1.4M monthly email + SMS revenue in under a year. Wilex: multi-language EU programme from zero to EUR 370K monthly. 50+ five-star partnerships at thrivelia.com. WE LEAD WITH VALUE Qualified brands receive a complimentary audit and a 12-month retention strategy mapped to the Hourglass. Yours to keep, with us or without us. Founder Trayan Hristov is the author of the Marketing Hourglass, a Klaviyo guest author, and has keynoted DTC Summit New York, Berlin Ecom Expo, Ad World, Foundr, and Shoptalk. Fully remote team between London and Sofia. Klaviyo partner since 2020.
