Klaviyo’s dominance in e-commerce email is well-earned — its Shopify integration, behavioral segmentation, and revenue attribution are best-in-class. But the pricing grows quickly with list size: 10,000 contacts cost $150/mo, 50,000 contacts cost $700/mo. For stores that have grown their lists faster than their email revenue, or that need multi-channel engagement at lower cost, the alternatives below deserve serious evaluation. The right Klaviyo alternative depends on whether price, channel breadth, or ease of use is driving the evaluation.

Klaviyo’s premium is justified when email attribution is measurable and the revenue generated per subscriber is high enough to make the per-contact cost trivial. When stores have grown large lists of less-engaged subscribers, the math shifts — you’re paying for contacts that aren’t generating proportional revenue. The right response is either cleaning the list (better on Klaviyo) or migrating to a lower-cost alternative for lower-monetization segments of your list.
