Klaviyo agency:
the whole platform, not half of it.

Not for everyone, and it's better to hear that before you're paying for it. Klaviyo bills by profile count and costs meaningfully more than Mailchimp-class platforms, with the gap widening as your list grows. It earns that premium when you're a commerce brand with real repeat-purchase potential. The store integration, behavioural triggers, predictive fields and segmentation depth translate directly into flows a cheaper platform can't run. If you send a fortnightly newsletter to a modest list, that capability is wasted and a simpler platform is the honest recommendation. We'll say so in the audit. And if you do choose Klaviyo, list hygiene stops being optional: on per-profile pricing, dead addresses aren't just a deliverability problem, they're a line on your invoice.

Some turbulence is a risk on any platform move. Anyone promising a painless overnight switch is glossing over how inbox providers work. Sender reputation doesn't transfer with your export; it has to be re-earned on the new sending setup. What we do is manage that in the open. Profiles, consent records and engagement history are mapped across in full, flows rebuilt and tested before anything is retired, and signup points switched over cleanly. Sending is warmed gradually, most-engaged segments first, so providers meet the new setup at its best. The old platform stays live until each piece is proven. Expect a managed transition over weeks, not a flip of a switch, and expect your numbers to hold rather than crater.

As deep as the platform allows, because that's where Klaviyo's value is. On Shopify: the full catalogue, order history, checkout and browsing events flow into Klaviyo, so abandonment triggers, product blocks and predictive fields all run on live data. On WooCommerce: the same through Klaviyo's integration, with event tracking verified rather than assumed. Woo setups vary, and a mis-wired integration silently starves every flow downstream. We build and maintain stores on both platforms. So when the fix is on the store side, such as a missing event, a slow theme, or a checkout quirk, the same team fixes it there instead of filing a ticket into the void.

Plenty of brands run Klaviyo perfectly well themselves. The platform is genuinely usable, and if that's you, the audit will say so. An agency starts paying for itself when the gap between what your account does and what it could do is worth more than the fee: flows unbuilt, segments unused, campaigns going to everyone, deliverability quietly slipping. That gap tends to grow with list size and catalogue complexity. Either way, nothing we build locks you in: the flows, segments and templates live in your account and are documented well enough that your team, or another agency, could take over tomorrow.

Flow builds and migrations are typically scoped as one-off projects, with an optional retainer for campaigns, segmentation and reporting afterwards. The price depends on how many flows and segments your list justifies, which is exactly what the audit establishes. Klaviyo's own subscription is separate and billed by Klaviyo. We'll help you choose the right tier and keep the profile count clean so you're not paying for dead addresses. Every proposal itemises deliverables so you compare like with like. You'll have a written, priced scope within 48 hours of the first call.

Look at the work itself. Ask how flows are sequenced, what the segments are built on, and how deliverability is checked before volume rises. Ask whether the store integration is verified or assumed. Then ask who owns the result: everything we build lives in your account, documented well enough for your team or another agency to take over.
