Tool comparisons

Klaviyo wins for pure Shopify e-commerce — the Shopify integration is significantly deeper and EU data residency is available at standard pricing. ActiveCampaign wins for businesses with B2B customers, complex sales pipelines, or those needing a CRM alongside their email marketing.

GetResponse wins on price and GDPR compliance out of the box — 500 contacts free, EU data storage by default, and significantly cheaper at every paid tier. Klaviyo wins for Shopify stores with 500+ contacts that need deep e-commerce automation and predictive analytics.

Omnisend wins for most UK Shopify stores — EU data residency by default, a Shopify app rating of 4.8, and a lower price at equivalent contact counts. Klaviyo wins for stores that need predictive CLV, very deep segmentation, and are comfortable configuring EU data residency manually.

If you are a UK Shopify store looking to replace Mailchimp, Omnisend is the best overall alternative — native Shopify integration, EU data residency by default, and a higher app store rating. GetResponse is better if you want a large permanent free tier. Klaviyo is better if you need deep predictive analytics. Brevo is better if you send infrequently to a large list.

Klaviyo wins for UK Shopify stores. Mailchimp removed its native Shopify integration in 2019, prices have risen significantly since the Intuit acquisition, and US-only data storage is the weakest GDPR position on this list. For stores that want native Shopify integration, EU data residency, and proper e-commerce automation, Klaviyo is the clear upgrade.

Both tools are EU-based with solid GDPR compliance by default — the main question is whether your store needs Omnisend's Shopify-first integration or GetResponse's larger free tier and all-in-one feature set. For Shopify stores, Omnisend is the better fit. For stores that also need landing pages, funnels, or webinars, GetResponse's scope is an advantage.
