HubSpot Marketing Hub vs Klaviyo
An independent, review-free comparison compiled by the SaaSTracker editorial team. Both products are profiled in full, and neither can pay for placement here.
The short answer
Both sides assessedHubSpot Marketing Hub compared with Klaviyo
The split is what you sell. Klaviyo bills by active profile from about $30 a month at a thousand profiles, reports in revenue rather than opens, and is built around abandoned-cart and post-purchase flows keyed to Shopify order data. HubSpot is built around forms, lifecycle stages, and deals on a CRM. Ecommerce brands get more from Klaviyo at every price point; B2B businesses with a sales conversation between interest and purchase get more from HubSpot, and few businesses genuinely need both.
Klaviyo compared with HubSpot Marketing Hub
HubSpot is the B2B answer to a question Klaviyo answers for ecommerce. Klaviyo's data model assumes orders, products, and repeat purchase, and its segmentation and revenue attribution are far stronger for a store than anything in HubSpot Starter. HubSpot's model assumes a lead who becomes an opportunity and eventually a deal, with marketing, sales, and service on one contact record. Choosing between them is really choosing whether your revenue arrives through a checkout or through a conversation.
Choose HubSpot Marketing Hub if
Small and mid-sized businesses with a content-and-forms funnel who want marketing, sales, and service on one contact database, and who can either live inside Starter's limits at $20 a seat or genuinely justify Professional at $800 a month plus $3,000 onboarding.
Choose Klaviyo if
Direct-to-consumer and ecommerce brands on Shopify, BigCommerce, or WooCommerce doing enough revenue that abandoned-cart and post-purchase flows pay for the subscription several times over, and who want segmentation driven by purchase behavior rather than by tags they maintain by hand.

13 attributes| Attribute | HubSpot Marketing Hub | Klaviyo |
|---|---|---|
| Category | Automation | ESPs |
| Starting price | $0 (free tools), then $20 per seat per month (Starter) (free plan available) | $0 (free up to 250 profiles), then roughly $30/mo at 1,000 active profiles (free plan available) |
| Pricing model | Tiered subscription combining per-seat pricing with a marketing-contact meter, plus a mandatory one-time onboarding fee on Professional and Enterprise. | Self-serve tiers priced by active (marketable) profile count, with a monthly email send allowance of roughly ten times the profile count; SMS is sold as a higher Email plus SMS plan with its own message credits, and the newer data, service, and AI product lines meter separately. |
| Free plan | Free marketing tools include forms, email marketing with HubSpot branding, live chat, ad management, and the full free CRM for up to two users. | Up to 250 profiles, 500 emails per month, $5 of mobile messages per month, and 10,000 Composer credits, with email support limited to the first 60 days. |
| Free trial | 14-day trials are offered on paid tiers; the free plan itself does not expire. | No fixed-length trial; the free tier up to 250 profiles is the evaluation path |
| Best for | Small and mid-sized businesses with a content-and-forms funnel who want marketing, sales, and service on one contact database, and who can either live inside Starter's limits at $20 a seat or genuinely justify Professional at $800 a month plus $3,000 onboarding. | Direct-to-consumer and ecommerce brands on Shopify, BigCommerce, or WooCommerce doing enough revenue that abandoned-cart and post-purchase flows pay for the subscription several times over, and who want segmentation driven by purchase behavior rather than by tags they maintain by hand. |
| Setup time | A day for Starter, including domain connection, forms, and a first email. Four to eight weeks for a serious Professional implementation, which is why the $3,000 onboarding fee exists and is charged. | An afternoon for a Shopify store to be sending. The store connector installs in one click and backfills order history, the onsite snippet goes on automatically, and the prebuilt flows can be turned on with default content the same day. Getting the flows genuinely good, with branded templates and considered branching, is a two to four week project. |
| Learning curve | Moderate. The interface is well designed and HubSpot Academy is genuinely excellent, but the platform is large, and the interaction between lifecycle stages, lists, workflows, and marketing-contact status confuses almost every new administrator for the first month. | Moderate and front-loaded. The flow builder and campaign sending are approachable, but segment logic over event properties is where people get stuck, because it asks you to think in terms of events and their metadata rather than in terms of lists. Anyone who has only used tag-based ESPs will need a week to stop fighting the model. |

Strengths and limitations
HubSpot Marketing Hub
Strengths
- The shared CRM database across marketing, sales, service, and content is the platform's genuine structural advantage and the reason workflows can act on deals and tickets without an integration.
- Reporting and multi-touch attribution are the best in this category by some distance, and they are the honest justification for Professional pricing.
- The largest integration ecosystem in the category, with more than 1,500 marketplace apps and a serious developer platform.
- The free tier and Starter are legitimately good, self-serve, and carry no onboarding fee, so evaluation costs nothing but time.
Limitations
- The Starter-to-Professional cliff is a forty-fold price increase with nothing in between, and it catches almost every growing small business.
- Mandatory onboarding fees of $3,000 on Professional and $7,000 on Enterprise are real money and are frequently omitted from vendor comparisons.
- Custom behavioural events are gated to Enterprise, which makes HubSpot structurally unsuitable as the lifecycle engine for a product-led SaaS company at any sane price.
- Crossing marketing-contact blocks bills immediately, which turns routine list operations into billing events and requires ongoing discipline.
Klaviyo
Strengths
- The data model is the real product: live segments over order history, browsing behavior, and predicted values give you targeting no tag-based ESP can express.
- Revenue attribution per flow and campaign is credible because Klaviyo already holds the order events, which makes the subscription defensible to whoever signs off on spend.
- Suppressed profiles stop counting toward the bill, so unsubscribes and bounces reduce cost rather than becoming permanent dead weight.
- Prebuilt ecommerce flows mean a new store can have abandoned cart, welcome, browse abandonment, and post-purchase live in days rather than designing automation from a blank canvas.
Limitations
- Expensive at scale. Roughly $720 a month at 50,000 profiles is several times what Brevo, Omnisend, or MailerLite charge for comparable list sizes, and the per-profile rate does not improve as you grow.
- The send allowance of about ten times your profile count constrains high-frequency senders, so a daily-mailing brand can be forced into a higher band by volume rather than by list growth.
- No advertised annual discount on self-serve plans, removing a lever that almost every competitor offers.
- The email editor is functional rather than delightful; teams coming from MailerLite or Kit usually find it a step down aesthetically.
Pricing compared
HubSpot Marketing Hub
Tiered subscription combining per-seat pricing with a marketing-contact meter, plus a mandatory one-time onboarding fee on Professional and Enterprise.
- Free$0
- Starter$20
- Professional$890
- Enterprise$3,600
Starter is good value and Professional is a genuine decision. At 5,000 marketing contacts, Starter with two seats plus four extra contact blocks lands around $240 a month but gives you almost no automation, while Professional lands near $950 a month in year one before the $3,000 onboarding fee, so call it $1,200 a month across the first twelve months. At 50,000 marketing contacts, Professional runs into the low thousands per month once contact blocks are added. Against EngageBay at roughly $240 a month for the same list size, or GetResponse at a few hundred, HubSpot has to justify a five to ten times premium. Sometimes it can: the attribution reporting, the shared CRM, and the 1,500-app marketplace are real and no cheaper tool matches them. Often it cannot, particularly for a SaaS team that will hit the behavioural-events ceiling and need a second tool anyway.
Klaviyo
Self-serve tiers priced by active (marketable) profile count, with a monthly email send allowance of roughly ten times the profile count; SMS is sold as a higher Email plus SMS plan with its own message credits, and the newer data, service, and AI product lines meter separately.
- Free$0
- Email (1,000 profiles)Approximately $30
- Email (10,000 profiles)Approximately $150
- Email (50,000 profiles)Approximately $720
- Enterprise and additional product linesQuoted
For a store with real order volume, Klaviyo at 1,000 or 10,000 profiles is straightforwardly good value, because the four standard flows typically return several multiples of the subscription and the attribution report proves it in a currency the founder already thinks in. The suppression policy is a genuine and underrated saving, since you are not paying rent on people who left. Value collapses in two situations: a large list without commerce revenue behind it, where $720 a month at 50,000 profiles buys reporting you cannot monetize, and a business that lets the SMS, reviews, and data product lines accumulate until the email tool costs enterprise money. Judged strictly as ecommerce email, it is expensive and worth it; judged as a general-purpose ESP, it is the wrong shape at the wrong price.
Editorial verdict on each
HubSpot Marketing Hub
Category LeaderHubSpot Marketing Hub is the safe answer and, at Starter, a genuinely good cheap one. The shared CRM, the attribution reporting, the ecosystem, and the training are real advantages no smaller vendor matches, and the free tier means evaluating costs nothing. The problem is the middle of the product line: Starter has almost no automation, Professional costs $800 a month plus a mandatory $3,000 onboarding fee, and there is nothing between them. For a SaaS company the second problem is worse, because in-product behavioural events sit behind a $3,600-a-month Enterprise tier, so HubSpot cannot be your lifecycle engine at any price a small company should pay. Use the free CRM and Starter for as long as they hold. When you outgrow them, price Professional honestly against EngageBay, GetResponse, and Ortto, and if your triggers are product events, buy a purpose-built tool instead and let HubSpot be the CRM.

Klaviyo is the correct default for an ecommerce brand with enough order volume that automated flows are a revenue line rather than a nice-to-have. The customer database underneath, the live segmentation over purchase and browsing behavior, and the revenue attribution that makes the spend defensible are genuinely a class above what general-purpose ESPs offer, and billing only for marketable profiles is a fairer meter than most of the category uses. The costs are real: no annual discount, a send allowance tied to list size, a per-profile rate that never improves with scale, and a growing set of adjacent products that each want their own line on the invoice. Buy it if a checkout produces your revenue and you intend to run serious flows. Do not buy it for a newsletter, a service business, or a big list with thin margins, where you will pay ecommerce prices for reporting you cannot cash.
