Klaviyo is an email and SMS marketing platform built for ecommerce, with a free plan up to 250 contacts and paid plans starting at $60/month as the contact list grows.
Budget at least $60/month (the entry paid tier above the 250-profile free threshold) plus separate SMS credit, and expect that figure to rise as the contact list grows.
About
In practice. What you can do with Klaviyo.
Klaviyo combines email and SMS marketing with a B2C CRM: it stores unified customer profiles, predicts lifetime value and churn risk, and lets a store build automated flows for abandoned carts, welcome series and post-purchase follow-up. It connects natively to Shopify, WooCommerce, BigCommerce, Magento, Wix and Salesforce Commerce Cloud, and an AI tool called Composer generates campaigns from a prompt.
The free plan covers up to 250 active profiles and 500 email sends a month, with $5 of SMS credit and support limited to the first 60 days. The entry paid tier starts at $60/month once the free profile threshold is crossed, and the price scales automatically with the number of active contact profiles; SMS is metered and billed separately from email, so total cost depends on both list size and messaging volume.
Practical uses
Recover abandoned cartsSet up an automated email and SMS flow triggered by cart abandonment on a connected Shopify or WooCommerce store.

Pros and cons. What Klaviyo does well, and what to expect.
Pros
Unified customer profiles with predictive lifetime-value and churn data go beyond what a basic email tool offers.
Native connectors for the main ecommerce platforms (Shopify, WooCommerce, BigCommerce, Magento) remove manual data syncing.
Cons
Price rises automatically as the contact list grows, independent of how many features are actually used.
Free plan support drops off after 60 days, unlike an ongoing free-tier support policy.
When it makes sense. Keep Klaviyo, or challenge it?
Keep if
You run an ecommerce store and want email, SMS and customer data in one connected platform instead of separate tools.
Klaviyo becomes worthwhile when
+You use it at least once a week
+The monthly cost ($60) is small next to the time it saves you
Challenge if
Your contact list is large relative to your budget, since Klaviyo's cost scales with active profiles rather than a flat fee.
Klaviyo becomes too expensive when
−You use it less than once a month
−A simple free version or a tool already in your stack would do
Our verdict. What to know about Klaviyo.
Why this verdict
Average
Added value
Klaviyo bundles email, SMS, a B2C CRM and predictive analytics that would otherwise need separate tools, but the full price ladder by profile count was not exposed in the sources, so the cost-to-value ratio beyond the $60/month entry rate cannot be confirmed.
Simplicity
Composer generates a campaign from a prompt, which speeds up that one step, but setting up ecommerce integrations, flows and segmentation is not detailed enough in the sources to judge overall time-to-first-result.
Fit for purpose
Email, SMS, WhatsApp, push and social ad sync are delivered natively alongside unified customer profiles, matching the omnichannel promise without third-party tools mentioned in the sources.
Performance
Predictive lifetime-value and churn analytics on top of omnichannel messaging and native connectors to the main ecommerce platforms go beyond a basic email tool's feature ceiling.
Reversibility
Neutral score: data export and account portability are not covered by the collected sources.
