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.

Most Klaviyo migrations are triggered by one of three moments: a list crosses 25,000 contacts and the monthly invoice suddenly feels disproportionate to email-driven revenue, a brand expands into SMS and finds Klaviyo’s combined channel pricing harder to justify, or a small team hits the limits of their technical bandwidth maintaining complex flows. Omnisend and Drip are the most common landing spots for mid-size e-commerce stores because both offer native SMS bundling and simpler automation builders at meaningfully lower price points. ActiveCampaign attracts stores that have outgrown pure e-commerce tooling and need CRM-style contact management alongside email. The honest trade-off in every case is that Klaviyo’s revenue attribution and predictive analytics are genuinely superior — switching means accepting some loss in reporting depth. Teams that switch and later return to Klaviyo almost always cite missing that attribution layer as the reason.

Klaviyo is built around email first, with SMS as a strong secondary channel, but it does not natively support push notifications, in-app messaging, or web push without third-party additions. If your retention strategy requires coordinating email, SMS, push, and on-site messaging from a single platform, tools like Omnisend or Braze offer broader channel coverage out of the box. Braze is enterprise-grade and priced accordingly, making it a realistic option only for brands doing significant volume with a dedicated CRM team. Omnisend sits in the middle ground — multi-channel at a lower price point, though its segmentation logic and predictive features do not match Klaviyo’s granularity. The decision reduces to a clear question: do you need to reach customers across more channels, or do you need to reach them more precisely through fewer channels?

Klaviyo charges by contact count regardless of how many emails you send, which rewards high-frequency senders but penalizes brands with large lists and modest send volumes. Drip and Mailchimp both use similar contact-based models, so they offer limited relief if list size is your primary cost driver. Sendinblue, now Brevo, prices by email volume rather than contacts, which can cut costs dramatically for brands with large lists that send two or three campaigns per month rather than daily. ActiveCampaign’s pricing scales with contacts but its mid-tier plans include CRM and automation features that Klaviyo charges nothing extra for because it simply does not offer them. Before committing to a migration purely on price, calculate your cost per sent email at your actual send frequency — the savings are sometimes smaller than the headline pricing difference suggests.
