ActiveCampaign vs Klaviyo: which is better in 2026?

These two platforms get cross-shopped constantly, and the comparison is less symmetrical than it looks. In our testing, ActiveCampaign scores 8.7 and Klaviyo scores 7.4, and the gap is not about raw capability. Both are deep, well-built platforms with 4.4-plus marketplace ratings. The gap comes from what each one costs to own over a year, how each bill behaves as your list grows, and how far each product’s center of gravity sits from the average buyer. ActiveCampaign is a marketing automation platform with a CRM bolted in; Klaviyo is a revenue engine for stores that live on order data. Below is where the numbers actually diverge.

Pricing and real cost at scale

The two vendors price on different logic, and that matters more than either sticker. ActiveCampaign sells four tiers (Starter, Plus, Pro, Enterprise) priced by contact count, quotes annual billing by default, and charges roughly 25% more month-to-month. Klaviyo sells one email plan priced purely on active profiles, bills month-to-month only, and advertises no annual discount anywhere on its pricing page. The figures below are annual-billing rates for ActiveCampaign (verified June 2026) and live-calculator rates for Klaviyo (read August 2026).

On stickers alone, Klaviyo looks cheaper at matched sizes: $100 versus $145 at 5,000 contacts, $150 versus $189 at 10,000, comparing against ActiveCampaign’s Plus tier. We compare against Plus deliberately. The $79 Starter figure at 5,000 contacts is a funnel: Starter omits the CRM, lead scoring, and predictive features that are the reasons most buyers pick ActiveCampaign over a cheaper tool, and it is not available at all above roughly 25,000 contacts. The realistic ActiveCampaign budget at 5,000 contacts is $145 per month, or $1,740 per year. The full tier-by-tier detail is in our ActiveCampaign pricing breakdown.

Klaviyo’s sticker has its own asterisks, and they are larger. First, the tier cliffs: $150 at 10,000 profiles becomes $225 at 11,500, a 50% price increase for a 15% larger list, and $300 at 13,000, double the 10,000-profile rate. By 25,000 profiles you are at $400 per month, about $4,800 per year. Second, the billing model: since February 18, 2025, Klaviyo requires every account to sit on a plan matching its total active profile count, so you pay for every emailable contact you store, whether you send to them or not. When your count crosses a boundary, the plan auto-upgrades at the next billing cycle; auto-downgrade exists only as an opt-in preference for credit-card customers. Third, SMS is never inside the headline price: the Email + SMS entry plan is $35 per month with just 150 SMS/MMS credits, US toll-free texts run $0.01 plus carrier fees each, and Klaviyo’s own calculator priced 2,900 monthly texts at roughly $40.

The honest summary: at a stable, pruned list size, Klaviyo email-only is cheaper than ActiveCampaign Plus. On a growing list, with no annual rate lock, automatic upgrades, and cliffs above 10,000 profiles, the year-two Klaviyo bill is far harder to predict than the year-two ActiveCampaign bill. You can model both against your own growth rate in our real cost calculator.

Automation depth and CRM

This is ActiveCampaign’s home turf. Its visual builder, with multi-path branching, goal tracking, wait-and-react steps, and re-entry logic, is the benchmark other email tools are measured against, and it is paired with site and event tracking, advanced segmentation, and a built-in CRM with lead scoring and a sales pipeline. Marketing automation and a sales process live in one tool instead of two that you have to sync. The 2025–2026 AI layer adds an automation builder that drafts a full sequence from a plain-text brief, and the integration list runs past 1,000, including a native Claude (Anthropic) connector. The caveat is gating: lead scoring, predictive sending, and attribution sit on higher tiers, which is exactly why Plus, not Starter, is the realistic plan.

Klaviyo’s flows are strong, but they are built around a different spine: order data. Real-time segmentation, predictive analytics, and revenue attribution on paid plans all assume there are purchases to attribute. For a B2B team running lead nurture, scoring, and pipeline handoffs, Klaviyo has no CRM and its automation depth is aimed at carts and catalogs, not deal stages. This is the clearest single divider between the two products: if you need marketing and sales automation in one place, the comparison ends here, in ActiveCampaign’s favor.

Deliverability

Deliverability is the metric that quietly governs email ROI, because mail that lands in spam cannot be opened, clicked, or attributed. Here ActiveCampaign has the strongest independent evidence in the category: in EmailToolTester’s latest round it placed 94.2% of messages in the inbox, ranking first out of 15 tools measured, against an 83.1% average for the group. That is roughly 11 percentage points of mail reaching a real inbox versus the typical tool in the test. The fair qualifier from our review stands: that is one strong round, ActiveCampaign’s average across the last three rounds is a good-not-perfect 4-star result, and your own list hygiene and authentication matter as much as the vendor’s infrastructure.

We do not have an equivalent placement figure for Klaviyo from the round we cite, so we will not invent one. What Klaviyo does offer on the sending side is volume headroom: every email tier includes monthly sends equal to 10 times your profile count, which is 100,000 emails at the 10,000-profile tier. That removes overage anxiety entirely, but included volume and inbox placement are different questions. If your revenue depends on transactional sequences, onboarding, and abandoned-cart mail actually arriving, ActiveCampaign’s measured number is the one concrete data point on the table.

Ecommerce and revenue attribution

Reverse the frame and Klaviyo leads. It is the platform ecommerce brands name first when the subject is email revenue, its G2 profile claims more than 170,000 businesses, and its ecommerce core, with Shopify, WooCommerce, BigCommerce, and Magento integrations, is where it is strongest among its 350-plus integrations. Paid plans include the pitch that justifies the price: revenue attribution, predictive analytics, and real-time segmentation that tell you which flow, campaign, and segment produced which dollars. Channel coverage is also wider than ActiveCampaign’s: email, SMS/MMS, RCS, WhatsApp, push notifications, social, and reviews in one tool, with email and SMS tiers upgrading independently so a brand heavy on one channel does not over-buy the other.

ActiveCampaign is not weak here. It has ecommerce automation, revenue reporting with first-touch-to-sale attribution, and deep Shopify and WooCommerce ties, and its top-tier deliverability directly benefits abandoned-cart recovery. But for a DTC store whose subscribers are worth dollars per year each, Klaviyo’s attribution machinery is the category default for a reason. The trade you accept for it is the billing model described above, plus add-on pricing with expiry dates: Composer AI lists at $157 per month (intro $110), Social at $50 at 10,000 profiles (intro $38 through 09/30/2026), and Reviews at $25 at 250 orders per month. Budget on the list prices, not the launch prices.

Ease of use and support

Neither tool is a same-afternoon product, but the curves differ. ActiveCampaign’s is well documented: teams report two to four weeks to fluency, and agencies run three to four training sessions before clients operate it alone. Its native forms and landing pages are functional but plainer than dedicated builders, and the mobile app is monitoring-only. Support scales with spend, with priority help effectively starting at Pro and Enterprise and no true 24/7 coverage on lower plans. Klaviyo scores 4.5 for ease of use on Capterra and is genuinely usable on the free plan, with one clock attached: email support on the free plan ends after your first 60 days, after which you are on documentation until you pay.

The trial math also differs. ActiveCampaign has no free plan at all, only a 14-day trial (no card required) plus a separate 30-day money-back guarantee. Klaviyo’s free plan has no expiry: 250 active profiles, 500 email sends per month, $5 of mobile message credit, and 10,000 Composer AI credits. For a very small store, that is a real evaluation path ActiveCampaign simply does not offer.

Independent ratings

Both platforms show the same two-faced pattern: loved on software marketplaces, disliked on Trustpilot. ActiveCampaign holds 4.4/5 on G2 across 14,647 reviews and 4.6/5 on Capterra across 2,561, was named to seven of G2’s 2026 Best Software Award lists, and has been the top-rated email tool on TrustRadius for eight consecutive years. Its Trustpilot score is 2.8/5 across 1,000-plus reviews, with the negative cluster centered on billing practices and support.

Klaviyo holds 4.6/5 on G2 across 1,361 reviews and 4.6/5 on Capterra across 537, with Capterra sub-scores of 4.6 for features and 4.5 for ease of use. Its Trustpilot score is 1.7/5 across 367 reviews, 57% of them one star. Our reading is the same for both vendors: the marketplace scores reflect the products, and the Trustpilot scores reflect the billing and account experience. Two differences tilt this category to ActiveCampaign. Its marketplace evidence base is roughly ten times larger, and its consumer-facing score, while poor, is a full 1.1 points above Klaviyo’s, whose one-star majority maps directly onto the auto-upgrading, profile-based billing described earlier.

Who should choose ActiveCampaign

Choose ActiveCampaign if you are a B2B or SMB team, or an agency serving them, running layered, behavior-driven journeys where automation depth, a built-in CRM, and inbox placement matter more than the lowest monthly bill. The archetype from our review is the 5,000-contact B2B SaaS on Plus at about $145 per month ($1,740 per year), running trial-to-paid sequences, lead scoring, and a pipeline that reacts to product behavior, with 94.2% measured deliverability protecting the onboarding mail that cannot afford to miss. Budget the ramp: two to four weeks to fluency is the documented norm, and if nobody on the team will invest it, much of what you are paying for becomes shelfware. The honest self-test from our review applies here too: if you cannot name two or three branching, multi-step journeys you want to build, you do not need ActiveCampaign yet.

Who should choose Klaviyo

Choose Klaviyo if you run an ecommerce brand with meaningful revenue per contact, your store sits on Shopify, WooCommerce, or BigCommerce, and your program is flows-and-campaigns driven. At 10,000 pruned profiles, $150 per month buys attribution, prediction, and segmentation depth that cheaper tools do not match, with 100,000 included sends removing volume worries entirely. Go in with two disciplines: model SMS as a second subscription, because it never rides inside the email price, and prune relentlessly, because a lazy 13,000-profile list pays $300 per month for the same engaged core a tidy 9,500-profile list gets for $150. Newsletter publishers and anyone with a large, lightly monetized list should look elsewhere entirely; per-profile billing punishes exactly that shape of business, and value picks like MailerLite (9.2 in our rankings) or Brevo (8.4) fit it far better than either tool on this page.

FAQ

Which is cheaper, ActiveCampaign or Klaviyo?

At a stable list size, Klaviyo email-only: $100 versus $145 at 5,000 contacts and $150 versus $189 at 10,000, against ActiveCampaign’s realistic Plus tier on annual billing. The picture changes with growth. Klaviyo has no advertised annual discount, auto-upgrades your plan when profiles cross a tier boundary, and jumps from $150 to $225 per month between 10,000 and 11,500 profiles. ActiveCampaign’s annual rates are locked for the term, and monthly billing runs about 25% higher.

Which is better for ecommerce?

Klaviyo, in most cases. Its revenue attribution, predictive analytics, and Shopify-centered integrations are built around order data, and email plus SMS scale independently. ActiveCampaign remains a credible ecommerce option, with revenue attribution and the best measured deliverability in the category at 94.2%, which directly benefits abandoned-cart mail. If subscribers are worth dollars per year each, Klaviyo’s machinery usually earns its price; if you also need a sales CRM, ActiveCampaign does both jobs in one tool.

Why does ActiveCampaign score 8.7 and Klaviyo 7.4?

ActiveCampaign earns its score on capability and evidence: the deepest automation builder in the category, a built-in CRM, 94.2% deliverability ranked first of 15 tools tested, and 4.4/5 on G2 across 14,647 reviews. Klaviyo’s product is genuinely strong, but its score is held down by the billing model, charging for every stored profile since February 18, 2025, with automatic upgrades and 50% tier cliffs, and by a 1.7/5 Trustpilot score across 367 reviews, 57% of them one star.

Does either tool have a free plan?

Klaviyo does: up to 250 active profiles and 500 email sends per month, with no expiry on the plan itself, though email support ends after your first 60 days on it. ActiveCampaign has no free plan at all, only a 14-day free trial with no card required, plus a 30-day money-back guarantee that some sources wrongly describe as a 30-day trial.
