HubSpot Marketing Hub vs Klaviyo

Positioning and orientation

HubSpot Marketing Hub is part of HubSpot's broader CRM platform and is oriented toward B2B and mixed-model companies that want marketing, sales, and service sharing one contact record. Klaviyo, headquartered in Boston, positions itself as a B2C customer relationship platform built for ecommerce, unifying storefront, order, and behavioural data to drive lifecycle marketing. In 2025 Klaviyo reported revenue of roughly $1.23 billion and introduced AI-driven marketing and customer agents. The two tools serve different buyers: HubSpot for pipeline-driven B2B motions, Klaviyo for transaction-driven retail and direct-to-consumer brands.

Data model and segmentation

Klaviyo's core advantage is a data model centred on shopper behaviour: orders, browsing, product catalogue, and predictive metrics such as customer lifetime value and churn risk, all available for segmentation and flows. HubSpot's data model is centred on the CRM contact and company, which is stronger for B2B attributes, deal stages, and lead lifecycle but lighter on native ecommerce signals without integration. For an online retailer, Klaviyo's purchase-aware segmentation is more immediately useful; for a B2B team, HubSpot's company and pipeline context is more relevant to how revenue is actually generated.

Pricing model

HubSpot bills on marketing contacts plus seats, with Professional near $890 per month and Enterprise near $3,600 per month, plus onboarding fees and overage charges as contact tiers fill. Klaviyo bills on active profiles, with a free tier to 250 profiles, an Email plan from about $20 per month, and an Email plus SMS plan from about $35 per month; at 5,000 profiles costs are roughly $175 per month. In February 2025 Klaviyo shifted to active-profile billing, which raised costs for some accounts and made list hygiene important. Pricing verified June 2026; enterprise pricing requires a quote. Klaviyo is cheaper to start; HubSpot charges for platform breadth.

Channels and ecosystem

Klaviyo combines email and SMS natively with strong ecommerce integrations, most notably a deep Shopify connection extended in 2026, plus catalogue and reviews tooling tuned to retail. HubSpot covers email, landing pages, ads, content, and a roughly 1,700-app marketplace, with social and SMS available through add-ons or partners. For a brand whose growth runs through a storefront, Klaviyo's ecommerce ecosystem is better aligned. For a company whose growth runs through sales reps and a CRM, HubSpot's marketplace and CRM-native tooling are the better match.

Company-size and use-case fit

HubSpot fits mid-market and enterprise B2B and mixed-model teams that want one platform across go-to-market functions and can absorb contact-tier pricing. Klaviyo fits B2C and ecommerce brands of all sizes that prioritise retention, abandoned-cart and post-purchase flows, and revenue per recipient. Klaviyo is not designed for complex B2B pipeline management, and HubSpot is not designed to be a purchase-behaviour engine for high-volume transactional retail; each is strongest in the model it was built for.

What buyers say

Buyers frequently note that Klaviyo excels for ecommerce, citing its purchase-aware segmentation, pre-built flows, and Shopify integration as reasons revenue attribution is clear and setup is fast for online stores. The most common concerns are rising costs after the move to active-profile billing and the platform's B2C focus, which limits fit for B2B sales motions. HubSpot users frequently highlight the unified CRM, ease of use, and the breadth of the app marketplace, while criticising cost escalation as contact tiers fill and weaker native ecommerce signals. Across both, sentiment maps cleanly to use case: ecommerce teams favour Klaviyo for its retail data model, and B2B or multi-function teams favour HubSpot for CRM unification, with friction arising mainly when a buyer applies one to the other's natural market.

When to choose HubSpot Marketing Hub

Choose HubSpot Marketing Hub if you run B2B or mixed-model marketing and want it unified with sales and service on one CRM, if attribution and a large app ecosystem matter, or if you are consolidating point tools onto a single platform. It is the better fit for mid-market and enterprise teams that can absorb contact-tier pricing in exchange for breadth and a shared data model across go-to-market functions.

When to choose Klaviyo

Choose Klaviyo if you run a B2C or ecommerce brand and need a data model built around purchase behaviour, deep Shopify integration, and native email plus SMS for retention and lifecycle marketing. It is the better fit for online retailers that prioritise abandoned-cart, post-purchase, and win-back flows, and that value fast setup and clear revenue attribution over full B2B CRM and pipeline management.
