Callum W.
Klaviyo & Email Marketing Specialist (29M+ USD in Client Revenue)
I help ecommerce and DTC brands turn email and SMS into their most profitable channel: $29M+ in attributed revenue and counting. If you're like most of my clients, you've got a great product… but your emails aren't pulling the weight they should. Flows that were "set up once" and never touched. Campaigns that go out but don't convert. A list you know is worth more than it's earning. That's where I come in. I'm a Klaviyo Partner (Top Rated, 100% Job Success) and I handle the full stack: strategy, automated flows, campaigns, copy, design and deliverability. Built and implemented for you, not just advised on. Think of me as the anti-agency option. You work directly with me, never an account manager. No agency layers, no waiting a week for a simple fix. I move fast, iterate quickly, build genuine long-term relationships with the brands I work with, and keep you on the best-performing, highest-converting tools rather than whatever's easiest. What I can do for you: -Build and optimise revenue-driving flows: welcome, abandoned cart, browse abandonment, post-purchase, win-back -Plan and design campaigns and newsletters that actually get opened and clicked -Write and design on-brand, mobile-ready emails (I do both copy and graphics) -Set up pop-ups and list-growth to feed the machine -Clean up deliverability, segmentation and reporting so you can see what's working A few results: £5M+ in email & SMS revenue for a UK swimwear brand $2.9M+ in email & SMS revenue for a US supplement brand $760K+ in email & SMS revenue for a US pet gear brand Tools I live in: Klaviyo, Mailchimp, ActiveCampaign. If that sounds like the kind of partner you've been after, send me a message and let's have a quick chat about your goals. No pressure, just honest recommendations. Speak soon, Callum
