Klaviyo
Email and SMS marketing platform for ecommerce campaigns, automation flows, segmentation, and retention reporting.
Last reviewed: 2026-07-22
Overview
Klaviyo sits between commerce and customer data sources and a merchant's outbound lifecycle marketing. Store events and customer profiles feed segments, campaigns, and automated email or mobile flows. Klaviyo can also host signup forms, but the storefront, checkout, order operations, and customer support remain separate operational systems.
Best for
Merchants that want ecommerce-focused lifecycle marketing, segmentation, and revenue-aware campaign reporting.
Not ideal for
Teams that only need a very simple newsletter tool or want minimal setup for automated customer journeys.
Implementation considerations
Review these dependencies before choosing a plan or committing to a rollout.
- 1Connect the ecommerce platform and verify that the events and profile properties needed for segmentation and flow triggers are arriving as expected.
- 2Migrate subscribers, consent status, and suppressions carefully; a profile created through checkout activity is not automatically the same as an opted-in marketing subscriber.
- 3Set up a branded sending domain and review SPF, DKIM, and DMARC requirements before scaling email volume.
- 4Prioritize foundational flows, define clear naming and ownership, and test trigger, filter, timing, and message logic before setting each flow live.
