Klaviyo vs ActiveCampaign: One Sends You Everything and Shows You Nothing

klaviyo vs activecampaign and its reverse draw 220 searches a month between them, a sixth of the Mailchimp pairing but the second-largest comparison in this category. The two products are further apart than that number suggests, and the most interesting difference is not a feature. It is what each one does with its own price list.

Klaviyo scores 3.88 on our eight axes. ActiveCampaign scores 3.44.

Two opposite failures of the same obligation

ActiveCampaign publishes its entire price list and displays almost none of it. Its pricing page yields 3,180 characters of extracted text containing no dollar amount at all, while the markup behind it runs to 1,410,272 characters carrying ten prices. The vendor's own billing catalogue, which that page fetches at load time using a token it issues to any visitor, carries eighteen products, fourteen metered entitlements and contact ladders of up to forty-nine bands. A second copy is published as a static file with no authentication.

Klaviyo does the reverse. It publishes no email tier price on its pricing page, and the page is not hiding a catalogue either: requesting it at ?contacts=5000 and ?contacts=25000 returns the same dollar amounts in the same counts ^[3]. There is no ladder to find, because the ladder is computed in the reader's browser.

So one vendor sends you everything and shows you nothing. The other shows you a calculator and sends nothing. A buyer ends up equally uninformed, and only one of the two could fix it by changing a template.

## What each one costs to start

	Klaviyo	ActiveCampaign
Free plan	yes: 250 profiles, 500 sends, $5 mobile, $5 Composer	none; a free trial only
Entry paid price	$20 a month, in a discount's terms	published per product, tier and band in the catalogue
Billing period	monthly	every published price is annual
Billing unit	active profiles, plus metered sends	contacts, with user seats as a second axis
Seats	not a pricing axis	1 included on Starter, 2 maximum

The free plan is the first real divide. Klaviyo has one and ActiveCampaign does not, which matters more than a feature comparison for anyone testing before committing. Klaviyo's free tier is also the only place in its product where the bill cannot move, because exceeding the limit stops sending rather than charging ^[5].

The second divide is the billing period. Every price ActiveCampaign publishes is annual, which makes its headline figures look closer to Klaviyo's monthly ones than they are. Klaviyo publishes no annual option at all.

The third is seats. ActiveCampaign prices on contacts and user seats together, capping Starter at two seats. Klaviyo does not charge per seat, which for a team of five is a material difference that neither pricing page makes obvious.

Depth against breadth

ActiveCampaign is a marketing automation product with a CRM attached, strongest on multi-condition automations and the logic between them. Klaviyo is a B2C customer data platform with channels attached, strongest on what it knows about a shopper and how many ways it can reach them.

Klaviyo carries six channels on one profile, a helpdesk, an AI support agent, a loyalty-aware customer portal and a data platform the vendor says holds 7.3 billion consumer profiles ^[12]. ActiveCampaign carries deeper branching logic, a sales pipeline, and the kind of B2B-shaped features, deal stages, lead scoring across a sales team, that Klaviyo does not attempt.

That is the honest shape of it. If your customer is a person buying a product, Klaviyo. If your customer is an account with a sales cycle, ActiveCampaign is built closer to that.

## AI, where the terms differ more than the features

Both products ship AI. Klaviyo publishes what it costs: Composer at twenty dollars a month with five dollars of usage included and ten dollars per thousand credits beyond, and Customer Agent at fifty dollars for seventy-five resolved shopper conversations ^{[5] [2]}. It also names the models it connects to, with published Claude and ChatGPT connectors and an MCP server ^{[15] [16]}.

ActiveCampaign's AI is metered from zero included units on its lower tiers, which is a different shape of risk: Klaviyo gives you an allowance and a rate, ActiveCampaign gives you a rate.

Klaviyo scores 4.2 on this axis. The score is for the terms, not the magic.

What ActiveCampaign's catalogue actually contains

It is worth describing, because it is the most complete price disclosure in this category and almost nobody has seen it.

The catalogue the pricing page fetches carries eighteen products, fourteen metered entitlements and contact ladders running up to forty-nine bands. That is a genuine price list: product by tier by band, with the metered extras alongside. It is served to every visitor's browser, and a second copy sits as a static file with no authentication at all.

What the visible page does is collapse three dimensions into one number. Price is a function of product, tier and contact band, and each card shows the first band of one tier of one product, prefixed "Starts at". Three things go missing in that collapse: the other bands, the other products, and that every published figure is annual.

Set that beside Klaviyo, where there is no catalogue to find. Requesting the pricing page at different bands returns identical dollar amounts ^[3], because the ladder exists only as arithmetic performed in the reader's browser.

Which is worse depends on what you mean. ActiveCampaign has published everything and informed nobody. Klaviyo has published one number and a method. Only the first could be fixed by changing a template, which is either a point in its favour or an indictment, depending on how charitable you feel.

## The free tier, which is the sharpest practical difference

Klaviyo's free plan is real and renewing: 250 active profiles, 500 email sends a month, five dollars of mobile messaging and five dollars of Composer usage ^[2]. It is also the only place in Klaviyo's product where the bill cannot move, because the published consequence of exceeding it is that sending stops rather than that the price rises ^[5].

ActiveCampaign has no free plan. It has a trial, whose length its pricing page states.

For a buyer, that difference is larger than it looks on a feature grid. A free tier lets you build a real flow against real data and discover whether the product fits before any money changes hands. A trial puts a clock on the same exercise, and the clock usually runs out during the part where you are waiting for someone else to send you the brand assets.

It also changes who can recommend the tool internally. A free account can be shown. A trial has to be justified first.

Integrations

Klaviyo claims 350+ and we could not count them. Its integrations directory serves 1,817,706 characters of markup that produce seven characters of visible text and name no integration at all ^[13]. What is verifiable is a strong ecommerce set: Shopify, BigCommerce, Magento, WooCommerce, PrestaShop, Wix, Square Online, Commerce Cloud: plus a public API and an MCP server.

ActiveCampaign's catalogue is, characteristically, fully published and awkward to read. Both score in the high threes on this axis for opposite reasons: one has a strong verifiable core and an uncountable claim, the other has a complete list nobody can navigate.

## The direction the bill travels

This is where the comparison gets practical.

Klaviyo's plan climbs automatically and by default, and comes down only when you arrange it, inside a twenty-four-hour window, with no refunds, and not at all while an invoice is open ^[5]. The auto-downgrade preference cannot run alongside the auto-upgrade that ships switched on ^[11].

ActiveCampaign's annual billing makes the same question look different: you are committing for a year, so the within-year ratchet matters less and the renewal conversation matters more. Neither is obviously better. They are different distributions of the same risk, and the right one depends on whether your list is seasonal.

The seat question, which neither page makes obvious

ActiveCampaign prices on two axes at once: contacts and user seats. Starter includes one seat and caps at two. Plus includes one and allows up to 999. Professional includes three, Enterprise five. So a five-person marketing team on Starter is not a cheaper plan; it is an impossible one, and the real comparison starts a tier higher than the card you were reading.

Klaviyo does not price on seats at all. The account costs what the profiles and the sends cost, whether one person or fifteen are logged in.

For a solo operator this changes nothing. For an agency, or a team where the designer, the copywriter and the analyst all need access, it is often the largest single difference between the two bills, and neither pricing page surfaces it next to the headline figure.

It also interacts with the annual commitment. If you add seats mid-year on ActiveCampaign you are amending an annual contract; on Klaviyo there is nothing to amend because seats are not a billable unit.

Scores, side by side

Klaviyo 3.88, ActiveCampaign 3.44, on identical weights for this category. Klaviyo's lead comes from capability at 4.5, AI at 4.2 and documentation at 4.0, the last being the highest documentation score we have given any product. ActiveCampaign's pricing transparency is better in a literal sense, everything is published, and worse in the sense that matters, because nothing is legible.

Both score poorly on support relative to everything else, which appears to be a category-wide pattern rather than a vendor-specific one.

Support and sentiment, where neither wins

Klaviyo scores 2.7 on support and reliability, its weakest axis by a distance. Across a hundred Trustpilot reviews we coded, support appears in fifty-nine and fifty-three of those are one or two stars ^[20]. The complaint has a consistent shape: "Putting the customer support behind a paywall is appalling!" writes one reviewer; another, on a large account, "We pay $4k a month and only have access to AI chatbots who take you around in circles."

That second sentence is worth sitting with, because Klaviyo sells AI support agents to other companies as a solution to exactly this problem.

ActiveCampaign scores poorly on the same axis for its own reasons. The pattern across this category is consistent enough that we would treat support quality as something to verify for yourself during a trial rather than something to infer from a score, whichever vendor you pick.

Klaviyo does publish more reliability data: 99.95% uptime alongside 2.5 billion daily events ^[12]. It also draws 720 searches a month for "is klaviyo down", and its status page yields no readable incident history to anything that does not execute its scripts.

If you are migrating between them

The import is not the cost. The flows are.

An account with mature automation: abandoned cart, browse abandonment, post-purchase, win-back, or on the ActiveCampaign side a branching nurture with scoring: represents months of iteration, and none of it transfers. Attribution history does not transfer either, so the year-on-year comparisons your reporting depends on restart on the day you switch.

The direction matters too. Moving to Klaviyo means rebuilding logic against a shopper profile that holds orders and behaviour, which usually simplifies what you had. Moving to ActiveCampaign means rebuilding channel work as branching logic, which usually expands it.

Budget a quarter of parallel running rather than a weekend, and do it in your quiet season.

## Who should pick which

Pick Klaviyo if you sell to consumers, want SMS and email on one profile, and value a free tier you can actually test with.

Pick ActiveCampaign if you sell to businesses, need branching automation and a pipeline more than you need channels, and can commit annually.

Pick neither on the headline price, because one of them publishes a year's figure next to the other's month, and both leave your actual band to a conversation.
