Klaviyo Agency
in 
Cardiff

Service
Mindwave builds Klaviyo programmes for Cardiff brands who've already worked with an agency, and want the person who pitched to be the person doing the work.

You've probably done this before

Cardiff has a real digital sector, which means two things at once. There are more agencies competing for this work than in most cities on this list, and the brands here tend to be more sophisticated buyers who've already been through one or two of them.

What we hear repeatedly from businesses in that position is the same complaint: they were sold a strategy by one person and then handed to someone junior who'd never seen the account before.

The people who pitch are the people who work

We're deliberately small, and the people you meet are the people in your account. That's a limit on how many clients we take rather than a slogan, and it's the main reason we can say it at all.

On the work itself, we come at Klaviyo from the inside, having worked at the company. That tends to show up in the unglamorous parts: data structure, deliverability, integrations that hold up, rather than templates that look good in a pitch deck.

Klaviyo for Cardiff brands

One of our founders worked inside Klaviyo, so we know what a healthy account looks like and can usually tell quickly what a previous agency missed.

We work remotely with Welsh brands, and you deal directly with the people doing the work rather than an account manager relaying messages.

Take us on for the full programme or slot us in beside your existing team. Either way, what Klaviyo learns can feed your wider marketing automation and your paid channels too.

Audit & Assess

We look at your existing flows, campaigns and segments to find what's underperforming and why. If you're starting fresh, we map out your customer data sources and build the full account structure before anything goes live.

Consultation & Onboarding

We agree on which flows to build first, connect your data sources and get your Klaviyo account linked to your other marketing channels. Most clients are live and sending within two weeks.

Launch, Optimise, Learn

We build and launch your flows, then our agentic AI monitors performance - tracking which sequences drive revenue, flagging drop-off points and suggesting improvements. Your automation gets more precise the longer we run it.

News & Views

We write about what we're seeing across paid search, paid social and marketing automation - what's changing and what's actually working.
