Klaviyo Email & SMS Copywriter (Brand Voice Specialist)

JOB DESCRIPTION

We're a UK e-commerce agency managing a portfolio of direct-to-consumer brands across food, skincare and confectionery, selling on Shopify and Amazon in the UK, EU and US.

We're looking for a Klaviyo specialist who is a copywriter first. You'll write and build email and SMS campaigns and flows that sound exactly like each brand. Every brand has its own guidelines, covering tone of voice, vocabulary, dos and don'ts, and visual rules. Your job is to follow them closely, so a customer could never tell that several brands share one writer.

What you'll do

Write campaign email s (launches, promos, seasonal, newsletters) and SMS for 3–5 brands
Write, rewrite and optimise core flows: welcome, abandoned cart and checkout, browse abandonment, post-purchase, replenishment, win-back and subscription (Recharge)
Build the email s in Klaviyo's drag-and-drop editor so they're on-brand, mobile-friendly and consistent with the brand guidelines
Write subject lines, preview text and A/B test variants
Set up segments, schedule sends and QA everything (links, personalisation tags, rendering)
Report monthly on open rate, click rate, conversion and revenue per recipient, and suggest improvements
Stay within regulated-claim rules for food and skincare products (no medical or unapproved health claims)

What we need from you

At least 2 years writing email copy for e-commerce/DTC brands, with at least 1 year hands-on in Klaviyo
Excellent written English. We sell mainly to UK customers, so you'll need to be comfortable with British spelling and tone
Proven ability to write in different brand voices. Please show us at least two contrasting examples
A strong understanding of flows, segmentation and deliverability basics
Great attention to detail and the ability to work from a brief and brand guide with little hand-holding
Reliable internet and some overlap with UK working hours (9am–1pm UK minimum)

Nice to have

Shopify and Recharge experience
Basic HTML/CSS for email
Canva or Figma for simple email graphics
Experience with food, supplement or skincare brands

How to apply
Start your application with the words "Brand Voice" so we know you've read this ad. Please include:

Links or screenshots of 3 email s you've written, including at least 2 for different brands
One Klaviyo flow you built and the results it got
A short answer: how do you make sure you stay on-brand when writing for several brands in the same week?

Shortlisted applicants will complete a short paid test: writing one welcome email from a brand guideline we provide.
