Klaviyo is a email and SMS marketing automation platform built to help users run email, SMS, customer segmentation, automation, and ecommerce retention campaigns. It gives teams a focused way to handle this workflow without stitching together too many manual steps.

The tool is most useful for ecommerce brands, lifecycle marketers, dtc teams that need a faster and more repeatable process. Depending on the use case, it can support content creation, campaign execution, sales workflows, customer communication, reporting, or production work.

For B2B teams, Klaviyo is worth considering when the current process is too slow, too manual, or spread across several disconnected tools. Before choosing it, compare pricing, integrations, workflow depth, and whether the platform fits your team size and operating model.
