Klaviyo pricing is based on the number of active profiles in your account and the volume of emails and SMS you send. Plans start free for up to 250 profiles and scale in tiers, so a brand with 50,000 profiles will typically pay several hundred dollars a month before SMS credits. That is the structure. The real question founders ask is whether it pays for itself.

In our experience running retention for DTC brands, the answer depends far less on the tier price and far more on how much of the platform you actually use. A Klaviyo account running three basic flows leaves most of its value unclaimed, while a well-built programme routinely drives 25 to 35% of total revenue from email alone.

This guide breaks down Klaviyo pricing, the hidden costs that catch brands out, how to cut the bill without cutting revenue, and the point at which the platform becomes the cheapest revenue channel you own.

How does Klaviyo pricing work?

Klaviyo charges on active profiles, every contact you can market to, with email and SMS priced as separate but connected plans. As your list grows you move up pricing tiers automatically, which is the detail that matters: the bill tracks list size whether or not those contacts generate revenue. Sending volume caps also apply per tier, though for most DTC brands the profile count is what drives cost.

The model rewards clean lists and punishes hoarding. Two brands with identical revenue can pay very different amounts purely on list hygiene.

What does Klaviyo cost at each list size?

The free tier covers up to 250 profiles, useful only for testing. From there, published pricing scales in bands: low tens of dollars monthly for a few thousand profiles, a few hundred dollars around the 50,000 mark, and four figures as lists move into the hundreds of thousands. Exact tier prices shift, so check Klaviyo's published pricing page for current numbers rather than relying on screenshots in blog posts. SMS sits on top, priced per message with credits varying by country; UK and US rates differ meaningfully, which matters for brands selling in both.

The hidden costs founders miss

The bill inflates in two quiet ways. The first is inactive profiles: every lapsed subscriber, bounced address and unengaged contact counts towards your tier, so brands routinely pay for a list a third larger than the one that generates revenue. The second is SMS credits, which are consumed per segment and per country at different rates, and can outrun the email bill entirely once campaigns get enthusiastic. Neither is a pricing trick; both are list and programme management problems that show up as platform cost.

How to reduce your Klaviyo bill without losing revenue

Run a sunset flow that suppresses contacts who have not engaged in six to nine months; suppressed profiles stop counting towards your tier and your deliverability improves at the same time, which lifts revenue from everyone who remains. Clean out role addresses and hard bounces, keep acquisition sources honest so junk never enters the list, and review SMS segments so credits go to buyers rather than browsers. Across the accounts our retention team manages, a first proper cleanup typically cuts the effective bill meaningfully while open rates rise, because you were paying to mail people who had already left.

When Klaviyo pays for itself: the 25 to 35% benchmark

The benchmark we hold accounts to is email and SMS driving 25 to 35% of total store revenue, with flows, the automated welcome, abandonment, post-purchase and winback sequences, contributing the larger share of that. At that level, Klaviyo's fee is a rounding error against what it returns, and it materially raises the customer lifetime value that decides what you can pay for acquisition. Meaningfully below 20%, the platform is not the problem; the programme is. This is the retention layer our sister studio Oaks builds and runs for DTC brands, working alongside the acquisition work we do as an ecommerce marketing agency, because the two compound: cheaper acquisition funds a bigger list, and a better programme makes every acquired customer worth more.

Frequently asked questions

Is Klaviyo worth it for a $5M+ brand?

Almost always, provided the programme is built out. At that scale a 25 to 35% email revenue share dwarfs the platform fee, and Klaviyo's Shopify integration and segmentation depth are hard to replicate on cheaper tools without giving up revenue.

How do I stop paying for inactive profiles?

Suppress rather than hoard. A sunset flow that suppresses contacts unengaged for six to nine months removes them from your billable count, protects deliverability, and can usually be set live in an afternoon.

When does switching to a cheaper ESP make sense?

When your programme is genuinely simple, a handful of campaigns, minimal segmentation, no SMS, and the price gap is large. If email drives a quarter of revenue, migration risk and lost functionality usually cost more than the saving.

Does SMS pricing sit inside the email plan?

No. SMS is a separate plan consuming per-message credits that vary by country, billed alongside email. Budget it separately, and check current rates on Klaviyo's pricing page for each market you sell into.
