Whether you've just launched your DTC brand and don't know where email should start, or you're scaling and sensing your store should be making far more from email but can't see what's missing, that gap usually isn't your product. It's your retention system.
Most Klaviyo and Brevo accounts are quietly leaking revenue. Flows set up once and never optimised. Campaigns blasted to the whole list with no segmentation. Deliverability issues nobody's watching.
I find exactly where the revenue is leaking and fix it.
I've spent 11 years building and optimising email and lifecycle programs for consumer brands, from large enterprise accounts to Shopify DTC. Along the way I've scaled programs to 110M emails/month, recovered inbox placement from 45% to 98%, and grown abandoned cart revenue 3.5x in 30 days.
Klaviyo Bronze Partner | Certified Klaviyo Strategist & Practitioner | PushOwl Partner | Brevo Certified
What I do:
1. Klaviyo setup & flow builds - welcome, abandoned cart, checkout abandonment, browse abandonment, post-purchase, win-back, replenishment, review request
2. Flow audits & optimisation - find what's underperforming and fix it with data, not guesswork
3. Campaign management - segmented sends that drive clicks and conversions, not just opens
4. Deliverability & inbox placement - SPF, DKIM, DMARC, sender reputation recovery, list health (a specialism: this is where I've delivered some of my strongest results)
5. SMS & push integration - high-intent touchpoints working alongside email
6. ESP migrations - moving to Klaviyo or Brevo from Mailchimp or any other platform, cleanly
I work with DTC and Shopify brands globally, with a focus on subscription, fashion and consumer brands that want retention to become a serious, predictable revenue channel. Not just another campaign that goes out.
If you need email built to perform, let's talk.
