HubSpot vs Klaviyo is one of the cleanest either/or decisions in marketing software — because it's decided by your business model, not by a feature battle. Klaviyo is built for ecommerce revenue; HubSpot is built for B2B, CRM management, and inbound marketing.
If you run an online store, almost everything about Klaviyo is tuned for you: it natively integrates with Shopify, WooCommerce, and BigCommerce, and nearly all of its features — flows, segmentation, ecommerce reporting — are available on the free plan. HubSpot, by contrast, is a full CRM platform where email is one channel among many, and store integrations plus advanced reporting live behind paid tiers.
Two different machines for two different businesses
Klaviyo's job is to turn a store's customer data into email and SMS revenue: abandoned-cart flows, browse-abandonment triggers, predictive lifetime value, and segmentation built directly on order history. HubSpot's job is to run a revenue operation — contacts, deals, pipelines, marketing automation, and (as your stack grows) sales and service on the same data model. Where Klaviyo goes deep on one motion, HubSpot goes broad: its app marketplace is several times larger than Klaviyo's, which starts to matter once your needs extend past email into sales and support tooling.
The pricing math, verified
As of July 2026, from both vendors' official pricing pages: Klaviyo's free plan covers 250 profiles and 500 emails/month, and at 10,000 active profiles the email-only plan runs roughly $150/month ($165 with SMS credits bundled) (Klaviyo, 2026). One caveat that surprises people later: Klaviyo bills on your total active profiles, not just the contacts you actually email — so the bill grows with your database, not your send list.
HubSpot Marketing Hub Professional is $800/month, which includes 3 seats and only 2,000 marketing contacts, plus a required $3,000 onboarding fee (verified July 2026 — HubSpot, 2026). The often-quoted “$150 vs $800” contrast is directionally fair but not apples-to-apples — and not in HubSpot's favor: at an equal 10,000-contact list, HubSpot's marketing-contact tiers push the real gap wider than the sticker prices suggest. HubSpot's counterweight is its free CRM (up to 2 users) and $20/seat Starter tier, which cover a lot of ground before the Professional cliff.
The honest verdict
If you run an online store, Klaviyo wins — on ecommerce-specific revenue tooling, on the free plan's generosity, and on price at every realistic list size. If you're a B2B company or service business, HubSpot is the more appropriate platform, because the thing you need isn't cart-abandonment flows, it's a CRM your whole team works out of — the same reason it beats ERP-style suites in Odoo vs HubSpot. And for hybrid businesses running both a store and a B2B sales motion, using both tools together is a legitimate answer, not a compromise.
Klaviyo's free plan is the obvious starting point for a store; HubSpot's free CRM is the equivalent for a B2B team. If Klaviyo's active-profile pricing feels heavy for a small list, the budget-focused alternative is covered in MailerLite vs Klaviyo.

Frequently Asked Questions
Is Klaviyo cheaper than HubSpot?
At comparable list sizes, yes — substantially. As of July 2026, Klaviyo runs roughly $150/month email-only at 10,000 active profiles, while HubSpot Marketing Hub Professional is $800/month and includes only 2,000 marketing contacts plus a $3,000 onboarding fee. The comparison isn't apples-to-apples, though: HubSpot is a full CRM platform, Klaviyo is an ecommerce email and SMS engine.
What does Klaviyo's “active profiles” billing actually mean?
Klaviyo bills on your total active profiles — everyone in your database who can be messaged — not just the contacts you emailed this month. A store that syncs its entire customer list pays for all of it, so costs scale with database size. Suppressing genuinely inactive profiles is the standard way to keep the bill aligned with reality.
Can I use HubSpot and Klaviyo together?
Yes, and hybrid businesses often should: Klaviyo running the store's email and SMS revenue flows, HubSpot running the B2B or wholesale sales motion. If your business genuinely has both motions, running both tools is usually cleaner than forcing either one to do a job it wasn't built for.
