The e-commerce specialist, deeply integrated with Shopify and built around predictive analytics and revenue attribution.
Best for
UK Shopify and e-commerce stores wanting deep platform integration and revenue attribution. Advanced automation on every paid plan, billed in USD.
Every fee we track, grouped by where it applies.
Klaviyo is the most deeply integrated email and SMS platform for e-commerce. Native Shopify, WooCommerce, BigCommerce, and Magento sync brings purchase history, browse data, and product catalogues into segmentation and automation, which is why serious online stores choose it.
All paid plans include the same advanced automation features (flows, predictive analytics, AI segments), so the only thing that scales with contact count is price. The free plan covers 250 active profiles and 500 monthly sends, and Klaviyo only counts active profiles, so suppressed and unengaged contacts do not push you into a higher tier. SMS to UK mobiles is supported natively (a UK text costs around 5 credits). Prices are billed in US dollars, with no native GBP option.
Klaviyo was founded in 2012 and is headquartered in Boston, USA.
Side-by-side with the closest alternatives by estimated cost.

Klaviyo starts at £15/mo (Email) on the Email plan for a small number of active profiles. Pricing scales by active profile count; suppressed and unsubscribed contacts are excluded from billing, which can reduce costs for stores with large inactive lists.
Klaviyo bills in US dollars, with no native pounds (GBP) option. Your invoice in pounds will therefore vary with the USD to GBP exchange rate. The table above shows the converted GBP figure at the current rate.

Both platforms target e-commerce stores and include email and UK SMS.
