Klaviyo Pricing Table: Every Contact Tier

Despite the steep tier jumps, Klaviyo's cost per active contact generally decreases as your list grows. At 500 contacts you pay $0.040 per contact per month. By 10,000 contacts that drops to $0.015. At 200,000 contacts you are paying just $0.012 per contact. The economies of scale do work in your favor over time.

The one exception is the 15,000 to 20,000 jump. At 15,000 contacts, your cost per contact is $0.013. At 20,000, it rises to $0.018. That is a 38% increase in per-contact cost, the only tier where the cost per contact actually goes up. If you are at 15,000 contacts and growing slowly, this is the tier where you should most aggressively clean your list. Suppressing 1,000 non-engaged profiles could keep you below the 15,000 threshold and save $150 per month.

List hygiene matters more on Klaviyo than on volume-based platforms like Brevo. Since Klaviyo charges by active profile count rather than email volume, every dormant subscriber costs you money even if they never open an email. A quarterly list cleaning routine where you suppress contacts who have not opened an email in 180 days can reduce your bill by 10 to 20% with no impact on revenue because those contacts were not engaging anyway.

Some stores implement an automated sunset flow in Klaviyo to handle this. The flow sends a re-engagement campaign to contacts who have not opened in 90 days. If they still do not engage after the re-engagement attempt, the flow automatically suppresses them. This keeps your list lean and your costs optimized without manual effort.

Each Klaviyo tier includes a set number of email sends per month, generally calculated at 10 times your contact limit. At 10,000 contacts you get 100,000 sends, which allows you to email your entire list about 10 times per month. For most e-commerce stores sending 2 to 4 campaigns per week plus automated flows, this is more than sufficient.

If you exceed your included sends, Klaviyo charges overage fees rather than cutting you off. The overage rate is approximately $0.001 to $0.002 per additional email, depending on your tier. A store with 10,000 contacts that sends 120,000 emails in a month (20,000 over the limit) would pay roughly $20 to $40 in overage fees on top of the $150 base plan.

This matters most during peak e-commerce seasons. During Black Friday and Cyber Monday week, many stores double or triple their usual email volume. If you normally send 60,000 emails per month but send 40,000 in a single BFCM week, you may hit your send limit by mid-month. Plan for this by either upgrading temporarily or budgeting for overage charges during Q4.

Once your list exceeds 200,000 active profiles, Klaviyo does not publish pricing. You need to contact their sales team for a custom quote. Based on reports from brands at this scale, pricing typically falls in the $2,300 to $4,000+ per month range depending on contact count, email volume, and whether you negotiate an annual commitment.

At this tier, Klaviyo also offers dedicated account management, custom onboarding, priority support, and dedicated sending infrastructure (dedicated IP addresses). These enterprise features are included in the custom pricing rather than charged separately.

Brands at this scale should also evaluate enterprise alternatives like Braze, Iterable, and Salesforce Marketing Cloud, which offer features like cross-channel orchestration, advanced data warehousing integration, and enterprise-grade SLAs that Klaviyo does not currently match. However, the migration cost from Klaviyo to an enterprise platform is significant (typically $50,000 to $150,000 in agency fees plus 3 to 6 months of implementation), so the move only makes sense if you are clearly outgrowing Klaviyo's capabilities.
