Klaviyo SMS review and pricing

Bundled SMS for the Klaviyo email customer base.

By Klaviyo, Inc. · Founded 2012 · Boston, MA · public

Klaviyo SMS is the SMS channel inside the broader Klaviyo platform, bundled with Klaviyo email and sharing the same profile, segmentation, and journey engine. It is not a standalone product, customers do not buy Klaviyo SMS without buying into the Klaviyo platform, and that is the point. For any Shopify-anchored DTC brand already on Klaviyo email, adding SMS in the same tool removes the cross-channel coordination problem that plagues standalone SMS plus email stacks. The trade-off: pricing scales aggressively on both the per-active-profile email side and the per-message SMS credit side, and the SMS-only buyer (a small subset) is overpaying for an email platform they will not use.

Best for

Worst for

Vendor Trust is scored independently of product quality. A great product from an unfair vendor still earns a low trust score.

  • “Adding Klaviyo SMS to our existing Klaviyo email setup took an afternoon. The same segments just work.”
