Klaviyo Pricing in 2026: Plans, Real Costs, and How to Lower the Bill

Klaviyo prices on your number of active profiles and your send volume. It starts free up to roughly 250 contacts and rises in tiers from there, with SMS billed separately as credits. The bill grows with your list whether or not those contacts buy anything. This guide explains the plans, the costs that surprise brands, and concrete ways to lower them.

We compete with Klaviyo, so read this as an informed-but-interested guide. The pricing mechanics below are accurate and vendor-neutral; the recommendation at the end is ours. If you just want the short version: the fastest way to cut a Klaviyo bill is to stop paying for contacts who never open anything, and the structural way is to stop pricing lifecycle on list size at all.

How Klaviyo pricing works

Klaviyo has three billing levers:

• Email plan (by active profiles). Your monthly price is set by how many contacts you can email, in tiers. As your list grows past each threshold, you move up a tier and the price steps up.
• SMS plan (by credits). Text messaging is priced separately, consumed as credits per message and segment, so an active SMS program adds a second meter on top of email.
• Free tier. Up to roughly 250 contacts and a small monthly send allowance, which is why Klaviyo is easy to start with and expensive to scale with.

The important detail is the unit of pricing: contacts you could email, not revenue those contacts produce. That single design choice explains almost every Klaviyo pricing complaint.

What actually drives your bill up

Three things, in order of how often they surprise brands:

1. Inactive profiles you are still paying for

List growth is treated as a cost, not just an asset. Every subscriber who has not opened an email in a year still counts toward your tier. Brands routinely pay for tens of thousands of contacts that produce nothing.

2. Crossing a tier threshold

Because pricing steps up in bands, adding a few hundred contacts near a threshold can push you into the next tier and a noticeably higher bill, even if sending volume barely changed.

3. SMS on top of email

SMS is metered separately. A healthy text program is valuable, but it is a second, usage-based bill running alongside the email plan, and it is easy to under-budget.

How to lower your Klaviyo cost

If you are staying on Klaviyo, these levers genuinely help:

• Prune and suppress inactive profiles. Regularly remove or suppress contacts with no engagement in 6–12 months so you stop paying for a tier you do not use.
• Send fewer, better-targeted campaigns. Large blasts to broad lists cost more, hurt deliverability, and rarely lift revenue. Tighter targeting lowers both send volume and spam complaints.
• Right-size your plan. Match your tier to the contacts you actually email, and review it every quarter rather than letting list growth drift you upward.
• Budget SMS separately. Track SMS credits as their own line so it does not become a surprise.

These reduce the bill, but they do not change the fact that you are paying on list size. The structural fix is to price lifecycle on outcomes instead.

What is cheaper than Klaviyo

Two paths. You can move to another flow-based tool - Mailchimp, Omnisend, Brevo - and trade some ecommerce depth for a lower price; we cover that in Klaviyo vs Mailchimp and Klaviyo vs Omnisend. Or you can leave the flow-and-list pricing model entirely.

That second path is what Relvino is. Instead of billing on how many contacts you could email, it runs autonomous 1:1 decisions - offer, timing, and channel per shopper in ~80ms - and wins by sending fewer, smarter messages. Brands replacing Klaviyo see a 3–7× lower bill, 80% less spam, and 2–6× ROI in 30 days, with up to 4× year-over-year revenue uplift versus Klaviyo. Fewer, better sends is both the cheaper and the higher-returning model. See Relvino pricing.

The bottom line

Klaviyo pricing is not unfair, it is just built on the wrong unit for a mature brand: your list. If your bill keeps climbing while results plateau, prune your list and tighten your sends first. Then ask whether lifecycle should be priced on how many people you might email at all. Compare the two models in Klaviyo vs Relvino, or see pricing.
