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.
Klaviyo has three billing levers:
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.
Three things, in order of how often they surprise brands:
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.
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.
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.
If you are staying on Klaviyo, these levers genuinely help:
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.
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.

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.
Start by pruning and suppressing inactive profiles, because you pay for contacts you could email whether or not they engage. Then send fewer, better-targeted campaigns to reduce send volume and protect deliverability, right-size your plan tier to the contacts you actually email, and budget SMS credits as a separate line. These help, but the bill is still tied to list size. The structural fix is to move to a model priced on outcomes rather than contacts.
Mailchimp is usually cheaper at a given contact count, but it trades away ecommerce depth: its Shopify catalog and event data is shallower, so the automation cannot get as specific. For a Shopify brand, the right comparison is not just sticker price but revenue per dollar spent. We cover it in detail in Klaviyo vs Mailchimp for Shopify.
For an early-stage brand, yes - the Shopify integration and template library earn it. For a larger brand with a lean team and plateauing results, the value question flips, because you are paying more each year to maintain a system that treats a segment as one person. At that point brands weigh the cost against autonomous decisioning, which delivers 2–6× ROI in 30 days at a 3–7× lower bill.
Other flow-based tools like Mailchimp, Omnisend, and Brevo are cheaper at a given list size but give up ecommerce depth. Relvino is cheaper for a different reason: it does not price on list size at all. By running fewer, smarter 1:1 sends it delivers a 3–7× lower bill with 80% less spam and a higher return.
No - it usually helps. Contacts who never engage do not produce revenue, but they do inflate your tier and drag down deliverability, which quietly hurts the sends that do matter. Suppressing them lowers cost and improves inbox placement at the same time.
With Relvino, the technical migration takes about 30 minutes: connect DNS, install the Shopify app, and your data ingests automatically. Flows are turned off, not rebuilt. From there a 14-day pilot proves revenue side by side - pause Klaviyo rather than cancelling, and compare.
