Which Klaviyo AI agents are worth paying for?

What AI agents does Klaviyo have?

Klaviyo now sells four products around its AI agents, and they are easy to confuse because they overlap: two sit under its K:AI banner and two under Klaviyo Service. Two are agents, one is an inbox for people, and one is an on-site surface the others feed.

Product	Who it works for	What it does	Status, November 2026
Composer	Your team	Audits flows, segments, forms and campaigns; answers questions about your data with the SQL behind them; drafts campaigns, flows and segments for approval; runs scheduled tasks and saved Skills	Generally available since 13 October 2026
Customer Agent	Your shoppers	Answers questions on web chat, email, SMS and WhatsApp, recommends products, tracks orders, handles returns and hands over to a person with context	Generally available since September 2025, expanded in June 2026
Helpdesk	Your support team	A ticket inbox for people, on the same customer profile as your marketing	Live, free Inbox if you do not buy
Customer Hub	Your shoppers	An on-site account area: orders, self-service, recommendations, favourites and a For You tab flows can write into	Live

Which ones are worth paying for depends on your account, and for some brands the answer is none of them yet. Everboost is a Klaviyo partner and uses Composer across client accounts every week, so this guide is written from day-to-day use.

How much do Klaviyo’s AI agents cost?

As of November 2026, the lowest published tiers in Klaviyo’s billing and Composer help articles are:

Product	Entry price	What you pay for	Worth knowing
Composer	Free (500 credits per cycle), then $20 a month	2,000 credits a cycle on the paid plan	Optional overage in $10 blocks of 1,000 credits; unused credits expire
Customer Agent	From $50 a month	Up to 75 conversations it handles	Billable once 48 hours pass after its reply with no response; one-time 50-conversation trial
Helpdesk	From $10 a month	Up to 50 tickets that need a person	Spam not billed; free Inbox after the trial
Customer Hub	From $20 a month	Up to 10,000 active profiles	Moves up or down a tier with your active profiles

At their entry tiers, all four together cost about $100 a month on top of your email plan, though Customer Hub costs more once you pass 10,000 active profiles. These are Klaviyo’s published US dollar list prices, before any VAT. That is small next to what a growing brand spends on Klaviyo itself, which is why the price is rarely the deciding factor. The real cost is the time someone on your team spends setting each one up and checking its work.

Two caveats before you budget. First, Klaviyo only publishes Customer Agent’s entry tier in its help centre; higher tiers appear in its plan builder, and third-party pages quote different figures for them, so price your own volume there rather than from a blog. Second, Customer Agent and Helpdesk both need Flexible Overages or Auto-Upgrade switched on, and unlike Composer there is no option to stop at the plan limit, so watch usage and switch the product off if it runs over budget. For the rest of Klaviyo’s bill, see our guide to how much Klaviyo costs.

Is Klaviyo Composer worth paying for?

For most brands that use Klaviyo every week, yes, and the $20 plan is the easy decision in this list. The free plan is enough to try it; the paid plan is enough to use it.

In Everboost’s use, audits are where it earns its keep. Klaviyo’s own estimates put a flow, form or template audit at $0.10 to $4.50 and a segment audit at $0.30 to $1.30, while creating a campaign runs from $0.10 to $10 or more depending on the request and how much you iterate. Composer finds broken flow filters, overlapping triggers and segments that quietly exclude the wrong people, usually for a few dollars or less per check. In our experience campaign creative is its weakest area for brands with a developed visual identity.

Since it came out of preview it has added shareable artifacts (now downloadable as a PDF or deck), Shopify price and discount edits, approval cards before sends and a usage meter that warns at 85%. Our full Composer guide covers what it is good and bad at. If you want an agent working on Klaviyo from outside the app, the Klaviyo MCP server is the other route.

Is Klaviyo Customer Agent worth it?

It depends on what your inbound looks like, and since 2 November 2026 it is much easier to measure. That day Klaviyo added source attribution, which breaks Customer Agent revenue down by flow, campaign and web chat conversation starter.

The maths is simple at the entry tier. At $50 for up to 75 conversations, Customer Agent costs about 67 cents a conversation. It pays for itself if it does one of two things:

1. Answers questions a person would otherwise answer. Repetitive pre-purchase questions suit it well for a health and wellness brand: what is in it, how do I take it, when will it arrive, how does the subscription work. If your support team spends hours a week on those, the time saved alone can cover the cost.
2. Turns a question into an order. A shopper asking which product suits them is close to buying. Source attribution now shows which flows, campaigns and chat starters lead to AI-assisted sales.

One rule matters more for this category than any setting: send anything about medication, pregnancy or a health condition straight to a person, and give the agent only the product wording your team has signed off.

Klaviyo says Customer Agent resolves 65% of questions on its own. That is Klaviyo’s figure, not an independent one, and your rate will depend on how good your knowledge base is.

One billing detail matters more than the headline price. A conversation becomes billable once the agent has replied and 48 hours pass with no response from the shopper, so a shopper who asks a question, reads the answer and leaves counts as a billed conversation, whether or not the answer helped. Klaviyo calls the unit a resolution, but the cost tracks questions answered. Conversations escalated to a person are not billed as Customer Agent conversations, though they count as Helpdesk tickets if you use Helpdesk.

How to test it: use the 50-conversation trial on web chat only, limit it to pre-purchase and order-status questions, give it your product, ingredient and delivery FAQs, and run it for a month. Then read source attribution as a starting point and ask your support team what changed. Everboost would make this call on the extra orders it creates and the support hours it saves, not on the resolution rate.

Do you need Klaviyo Helpdesk if you already have a support tool?

Usually not straight away. Helpdesk’s advantage is that tickets sit on the same Klaviyo profile as a customer’s orders, flows and campaigns, so a support agent can see that someone just got a renewal reminder, and support activity sits on the same profile your marketing uses. That is useful, but it is a migration decision, not an add-on decision.

If you already run Gorgias, Zendesk or another helpdesk with macros, integrations and reporting your team relies on, the cost of moving usually outweighs anything you would save. Helpdesk makes most sense for a brand that has outgrown a shared inbox and has not committed to a support tool yet, or one already buying Customer Agent that wants escalations to land in the same place. If you trial it and do not buy, Klaviyo drops you back to the free Inbox rather than switching it off. Everboost does not run support for clients, so we judge Helpdesk by what it does for retention data, and that alone does not justify a switch.

What is Klaviyo Customer Hub, and is it worth it?

Customer Hub is an on-site account area: order tracking and self-service support alongside personalised recommendations, favourites and a For You tab that flows can now write messages into. Paid plans start at $20 a month for up to 10,000 active profiles.

It is worth testing if your customer account page today is just a list of past orders, because that page is mostly visited by existing customers, the people most likely to buy again. It is less useful if your subscription platform already runs the account area where subscribers manage deliveries, because two account areas confuse people. For a subscription brand, the subscriber portal is the account page that matters most, and Customer Hub should sit alongside it. The portal is also where the cancellation flow lives, which is where much of our work with a UK electrolytes brand happened.

Klaviyo’s pricing page includes Customer Hub in the free plan, but its help documentation says product recommendations, favourites and FAQs need a Customer Hub trial or paid plan, so check what your own account includes. It is also not available on accounts with EU data residency. Everboost treats the account page as part of the post-purchase journey, which is where a second order is usually won or lost.

What is the difference between Composer and Customer Agent?

Composer works for your team; Customer Agent works for your customers. Composer reads your account, finds problems and drafts work for you to approve, and nothing it makes reaches a customer without sign-off. Customer Agent talks to shoppers directly, within the knowledge and rules you give it. They are priced separately and you can buy either without the other. Since 16 October 2026 you can build and test Customer Agent from inside Composer, the clearest link between them so far.

The naming adds confusion. Klaviyo launched a Marketing Agent in September 2025, and older articles describe that product. As of November 2026 Klaviyo’s navigation labels Composer as its AI marketing agent, so Composer is the one to evaluate. What was announced alongside these products at K:BOS is in our K:BOS 2026 breakdown.

What do the agents not do?

They mostly see Klaviyo and whatever you connect to them. Composer can tell you a flow filter is broken; unless that data reaches Klaviyo or a connected app, it cannot tell you that the product it is promoting has a thin margin or is the one generating most of your refund requests. Customer Agent can answer a question about an ingredient; it does not know which answer your regulatory team signed off unless you give it that wording.

As of November 2026 the agents are strongest on work that has a checkable right answer. Deciding what to send, to whom and why is still a commercial decision, and Klaviyo’s design reflects that by asking for sign-off on every Composer action that reaches a customer. That is the same line we draw in our review of Klaviyo’s weaknesses.

What should you do?

• Using Klaviyo every week, not using Composer yet: pay the $20, use it for audits first, and save your brand rules as Skills so the output stays consistent.
• Busy support inbox full of pre-purchase questions: test Customer Agent on web chat for a month on a narrow scope, then judge it on extra orders and support hours, not resolution rate.
• Happy with your current helpdesk: leave Helpdesk alone unless you are already buying Customer Agent.
• Thin customer account page: trial Customer Hub, and if you sell subscriptions, plan how it sits next to your subscriber portal before you switch it on.
