What does Klaviyo cost?

Short answer
Klaviyo starts free for small lists and scales from there with the number of contacts (and whether you use SMS). For a growing e-commerce store, the ongoing cost is typically modest against the revenue a well-run flow and segmentation engine generates.
Sådan virker det
Klaviyo har en gratis start-tier og skalerer derfra med antallet af kontakter (og om du bruger SMS). For en voksende webshop er den løbende pris typisk beskeden i forhold til den omsætning, en veldrevet flow- og segmenteringsmotor genererer.
01The price scales with the value
Klaviyo's price follows the number of active contacts on your list: a small list can run free or cheap, and the price rises as the list — and with it the potential — grows. SMS is billed on top by usage. The model means the cost roughly tracks the value the channel can create.
It's worth remembering that the platform price itself is rarely the big question. A well-run Klaviyo account, where flows and segmentation exploit purchase data, typically accounts for a meaningful double-digit share of revenue — so the platform price pays for itself many times over, if the setup is built right.

02The real cost is setup and operation
The biggest “cost” of Klaviyo isn't the subscription, but the work of building and running it: flows, segmentation, design, deliverability and ongoing optimisation. An empty Klaviyo subscription earns nothing; it's the flow and segmentation engine on top that drives the revenue.
So the decision shouldn't be about the platform price, but about what a well-built setup can add to the bottom line — and whether you have the capacity to build and maintain it yourself, or want a partner to own it.
Frequently asked questions
Is Klaviyo free?+
There's a free tier for small lists with limited volume. From there the price scales with the number of contacts, and SMS is billed by usage. For most growing e-commerce stores, the ongoing cost is modest against the flow-driven revenue.
Is Klaviyo worth it over a cheaper tool?+
For an e-commerce store where retention is a growth channel, usually yes — the e-commerce-specific flows and purchase-data-driven segmentation often drive enough extra revenue to outweigh the price difference many times over.
