Klaviyo Review 2026: Pricing, Features, and Who It Fits

Klaviyo is a strong but fairly expensive marketing platform for businesses with repeat customers and useful behavioral data, most often Shopify and other online stores. It's free for 250 active profiles, then the US Email plan runs about $20 a month at 500 profiles and $150 at 10,000. It pays off when customer behavior (orders, carts, bookings, renewals) changes what you send next. It's a poor buy for a simple newsletter.

Disclosure and method: Dreamlit, the company behind this blog, is building an email product for Shopify stores, so we have an interest in this category. Prices and product rules come from Klaviyo's pricing page and help center. Interface observations come from EmailTooltester's hands-on review⁠, last updated August 24, 2026. We didn't run a fresh end-to-end Klaviyo test for this update.

What is Klaviyo and how does it work?

Klaviyo collects customer data (who someone is and what they did), then uses it to decide who gets which message and when. It now calls itself⁠ "the autonomous B2C CRM," with marketing, service, analytics, and data products on one platform. For most buyers, the core is still marketing automation.

Five building blocks do the work:

• Profiles hold each person's contact details, consent, and history.
• Custom properties store current facts, such as membership tier, preferred store, or renewal date.
• Events record actions such as Placed Order, Started Checkout, or Booked Stay. Each event type is a metric.
• Segments group people by properties, events, engagement, and location.
• Flows send messages automatically when an event happens, a date arrives, or someone joins a list or segment.

Here's how that plays out in a Shopify store. The integration records a checkout event once a shopper enters their email address at checkout. An abandoned-checkout flow waits a few hours, checks whether a Placed Order event arrived, and if not, sends an email showing the exact items left behind. The same events feed a "bought twice in 90 days" segment and the revenue report that tells you what the flow earned.

Can you use Klaviyo without Shopify or an online store?

Yes. Shopify makes Klaviyo easier to start, not uniquely capable. Klaviyo works whenever you can feed it reliable profiles and events. There are three ways to get that data in:

The warehouse importer⁠ handles events, not profile properties, and needs a timestamp and profile identifier on each row. Custom data is enough for flows and segments. Predictions need Placed Order events with order values, and product-based features such as product feeds need a product catalog.

Klaviyo features: where it's strongest

Behavioral segmentation

Segments combine profile properties, message engagement, location, and behavior. Most update close to real time⁠; conditions based on relative time may update once a day. A store can target "bought a candle in the last 90 days but hasn't opened the last three emails" without exporting a spreadsheet. A gym can find members whose attendance is dropping.

Event-triggered flows

Flows start from an event, a date property, a list, or a segment. That covers abandoned carts and post-purchase follow-ups, but also trial onboarding, reservation reminders, renewals, and win-backs. Re-entry controls⁠ decide whether someone can go through a flow again and how often.

Ecommerce integrations and revenue attribution

Shopify, BigCommerce, WooCommerce, and other integrations sync orders, products, and customers without a custom pipeline, though browse tracking may need an onsite snippet. Stores get ready-made abandoned-cart, post-purchase, win-back, and back-in-stock flows, plus revenue attribution per campaign and flow.

Predictive analytics, with real eligibility rules

Klaviyo predicts customer lifetime value, churn risk, and expected next order date, and shows each customer's historical average time between orders. These models need purchase data. To qualify⁠, an account needs:

• At least 500 customers who have placed an order that wasn't cancelled, refunded, or zero-value
• At least 180 days of order history
• An order within the last 30 days
• Some customers with three or more orders

A custom integration can qualify if it sends correctly mapped Placed Order events with values. Lesson completions or bookings alone won't make an account eligible.

Campaigns, forms, and channels

The same profiles and events drive campaigns, sign-up forms, and flows across email, SMS and MMS, WhatsApp, RCS where supported, and mobile push. The free plan is enough to test the editor, forms, flows, segmentation, and reporting.

What EmailTooltester found in its hands-on review

This is a short synthesis of EmailTooltester's review⁠, not our own product test.

The editor and forms are approachable. Data design, advanced segmentation, and migration are the hard parts.

How much does Klaviyo cost in 2026?

Klaviyo is free up to 250 active profiles; the US Email plan then starts at about $20 a month and reaches about $150 at 10,000 profiles. Klaviyo's pricing page is an interactive calculator, so totals change with profile count, sends, region, mobile usage, and add-ons. Checked September 2026.

The free plan⁠ includes:

• Up to 250 active profiles
• 500 email sends a month
• $5 of mobile messages a month
• Basic templates, the drag-and-drop editor, forms, segmentation, and reporting
• Email support for the first 60 days only

Approximate monthly US Email plan prices:

These come from Klaviyo's US calculator. EmailTooltester's August 2026 pricing breakdown⁠ lists the same prices at the tiers it covers. Your quote is the source of truth.

How active-profile billing works

Since February 2025, your plan must cover every active profile⁠: anyone who can be emailed through Klaviyo, whether or not you emailed them this month. Each paid tier also includes a monthly email allowance⁠ of about 10 times its profile limit.

That's why list hygiene matters more on Klaviyo than on send-based tools. Suppressing or deleting dead profiles lowers the count, but the refresh can take up to 72 hours, and a lower bill only applies after you move to a smaller plan at your next billing cycle.

Mobile messaging pricing after July 13, 2026

Klaviyo moved SMS, MMS, WhatsApp, and RCS from credits to dollar-based pricing⁠. New customers and free accounts switched on July 13, 2026. Existing paid mobile subscriptions switch on their first billing date after August 13, 2026, and Klaviyo says it will never move anyone to a higher-cost tier automatically.

Under the new model you prepay a monthly dollar amount. Klaviyo's calculator shows $15 a month buying about 1,000 US SMS from a toll-free number. Each message draws the balance down at a rate that depends on channel, country, and number type (toll-free or short code in the US and Canada), with carrier fees included. Unused dollars don't roll over⁠. Check your billing settings for your exact rates.

Which capabilities cost extra?

The Email plan price doesn't cover everything on Klaviyo's platform page.

Six Klaviyo examples beyond ecommerce

These are illustrative event designs, not prebuilt templates. Each works only if the source system sends accurate identifiers, timestamps, and properties.

Completed Lesson isn't a store event, but it answers the same question as Viewed Product: what did this person show interest in, and what should happen if they stop?

What does non-ecommerce setup really cost?

Custom events add flexibility, but someone has to build and maintain them. Budget for:

• Event design: Stable names, timestamps, identifiers, and properties before campaigns depend on them.
• Monitoring: API calls fail and fields change, and a broken pipeline doesn't announce itself in the campaign editor.
• History: Sending new events is easy. Rebuilding enough history for segments or predictions is harder.
• Consent and governance: Only send data you're allowed to use for marketing. Sensitive attributes need legal and security review first.

For a custom application, count engineering time and an ongoing owner in the total cost, not just the subscription.

Where is Klaviyo a weaker fit?

• Simple newsletters: If everyone gets the same message, a newsletter tool is faster and cheaper. Our small-business email guide⁠ covers that category.
• Large, quiet lists: You pay for every active profile. Suppressing dormant contacts lowers the bill, but also stops you from marketing to them.
• No data owner: Event naming, identity, consent, and monitoring need an owner, or automations quietly go wrong.
• Transactional-first products: Klaviyo supports approved transactional messages inside flows⁠, not a general email API or SMTP relay.

How does Klaviyo compare with alternatives?

• Omnisend: Store-focused email and automation at a lower price, with SMS on its Pro plan. See Omnisend vs Klaviyo⁠.
• Mailchimp: Broader small-business campaigns and newsletters, with a shallower data model. See Klaviyo vs Mailchimp⁠.
• Shopify Messaging (formerly Shopify Email): Built into Shopify, with 10,000 free emails a month. Enough for many small stores.
• Customer.io: For product teams that already run lifecycle messaging on custom app events.

The full field, grouped by reason for switching, is in our best Klaviyo alternatives⁠ guide.

Is Klaviyo worth it in 2026?

Yes, when repeat customer behavior changes what you should send next, and someone owns the data. Klaviyo is a strong choice when most of these are true:

• You have repeat B2C customers, whether or not they buy through a store.
• You can connect their behavior through a native integration, the API, or a warehouse.
• The value of each active profile supports the price.
• Someone will own the flows and data after launch.

Look elsewhere when you mostly send one newsletter to everyone, your list is large but rarely buys, your data stops at names and emails, or you mainly need a transactional email API.

Where Dreamlit fits

If you run a Shopify store, Dreamlit is building AI email automation for Shopify, currently in beta. You describe an email in plain English, and Dreamlit designs it on-brand from your orders, customers, and products. It can react to new orders, abandoned checkouts, fulfilled shipments, refunds, returns, and restocks, build segments you describe in plain English, attribute revenue, and honor consent and unsubscribes. It's in beta and focused on email for Shopify stores, so it's not a like-for-like replacement for Klaviyo's wider platform. Join the Shopify beta⁠.

Frequently asked questions

How much does Klaviyo cost in 2026?

The free plan covers 250 active profiles, 500 email sends a month, and $5 of mobile messages. In September 2026 the US Email plan cost $20 a month at 500 active profiles, $30 at 1,000, $100 at 5,000, $150 at 10,000, and $720 at 50,000. Mobile messaging and products such as Marketing Analytics or Advanced KDP cost extra, so check Klaviyo's calculator for your setup.

Does Klaviyo have a free plan?

Yes. It covers up to 250 active profiles, 500 email sends a month, and $5 of mobile messages a month, with forms, segmentation, reporting, and basic templates. Email support is included only for the first 60 days. An active store will outgrow it quickly.

What counts as an active profile in Klaviyo?

Any profile that can be emailed through Klaviyo counts as active, whether or not you email it that month. Suppressed profiles don't count. If your account has 8,000 active profiles but you only email 3,000, your plan still has to cover 8,000.

How does Klaviyo mobile messaging pricing work?

Klaviyo replaced SMS credits with dollar-based pricing. New customers and free accounts switched on July 13, 2026, and existing paid mobile subscriptions switch on their first billing date after August 13, 2026. You prepay a monthly amount (for example, $15 covers about 1,000 US toll-free SMS), each message draws it down at a rate that depends on channel, country, and number type, and unused dollars don't roll over.

Can you use Klaviyo without Shopify?

Yes. Shopify is Klaviyo's most convenient integration, not a requirement. You can import profiles, send custom events through the Events API, connect another supported integration, or import warehouse events with an Advanced Klaviyo Data Platform subscription.

Is Klaviyo good for non-ecommerce businesses?

It can be, when customers come back repeatedly and you can send useful behavior into it, such as bookings, class attendance, lesson progress, or subscription renewals. Gyms, travel operators, course providers, and consumer apps use it this way. Budget for the integration work, and don't expect commerce-only features like purchase predictions to apply.

Is Klaviyo worth it compared to Mailchimp?

For an online store, usually yes: Klaviyo's order-based segments, flows, and revenue reporting go deeper than Mailchimp's. For a newsletter or service business with little behavioral data, Mailchimp is simpler and often cheaper.

Is Klaviyo hard to learn?

Campaigns, forms, and a first abandoned-cart flow are approachable. The learning curve shows up in complex segments, conditional flows, and custom event integrations. Stores on a native integration get started faster than teams sending their own events.
