What buyers say about each platform

Every buyer interview spends its minutes somewhere — praising the thing that won the deal, or flagging the thing that still stings. Map where those minutes go for Klaviyo and HubSpot, and the chart below shows where each platform's praise and complaints concentrate in these interviews — not a ranking of what either can do:

Praise Complaints

Ecommerce email versus marketing inside the CRM. Klaviyo's praise concentrates on store fit, email and ease, and its complaints on price and orchestration beyond email. HubSpot's praise concentrates on ease and on marketing and CRM together, and its complaints on data flexibility, consumer-ecommerce fit and price.

Relative share of buyer commentary by theme in Alium's verified interviews, praise vs. complaint, through October 2026. Widths compare themes within this pair — they are relative, not counts. Each vendor's widths are normalized to its own commentary, because Klaviyo appears in far more interviews.

In their own words

The phrases buyers reach for, verbatim, when they describe each platform:

Where Klaviyo buyers concentrate their praise

Klaviyo buyers concentrate their praise on ecommerce fit — “Klaviyo as an ESP has an incredible connection with Shopify,” says one — and on email built around store data: browse and cart behavior, product catalogs and purchase history. One calls it “as powerful of an email platform as there is out there,” and marketers describe running it without engineering: “I can jump into Klaviyo today and set up everything.” The complaints concentrate on price, especially as lists grow — “their pricing model has gotten a little bit crazy,” says one — and on what sits outside consumer email and SMS. Klaviyo's store-focused data model does not fit every selling process equally well. One company with quote-based sales added HubSpot because its Klaviyo setup did not support the email and SMS workflows it needed around quotes: “Klaviyo doesn't allow you to send emails or SMS messages to quotes.”

Where HubSpot buyers concentrate their praise

HubSpot buyers concentrate their praise on ease of use — “HubSpot is literally as easy to run as Gmail,” says one — and on marketing and CRM working together: email, automation, social and the sales pipeline in one place, “fully integrated versus having to bring in a third party.” One describes “a tremendous amount of power on the marketing automation side.” The complaints concentrate on data flexibility — reporting, segmentation and custom data that buyers outgrow; “Their segment builder still is unintuitive,” says one — and on fit for consumer ecommerce, where buyers describe it as a B2B tool: “Klaviyo is built for those things, HubSpot is not.” Pricing splits its buyers: some find it good value, and others describe costs that climb with tiers and add-ons, “where everything you click on is an upgrade path.”

Companies running both usually split them by business model. One describes it plainly: “We use Klaviyo for our D2C emails. We use HubSpot for our B2B emails.” Moves between the two run both ways. A brand that moved consumer email to Klaviyo explains that in a direct-to-consumer environment “it's hard to segment to pull behavior” in HubSpot. Others consolidated onto HubSpot to keep marketing inside the CRM and contract they already had. On price, buyers who already run HubSpot describe Klaviyo as the harder add-on to justify: one would like Klaviyo but says “I don't think it's right in our price range and probably would be told to just use HubSpot instead.”

What buyers wish they'd known

Four questions the interviews raise

01

Do you sell to consumers online, to businesses, or both?

Klaviyo

Companies running both usually give it consumer email and SMS.

HubSpot

Companies running both usually give it the CRM, the sales team and B2B email.

02

How much of your marketing depends on store behavior?

Klaviyo

Ecommerce and Shopify fit are among its most-praised themes.

HubSpot

Consumer brands describe behavioral segmentation as harder; fit for ecommerce draws more complaint than praise.

03

Do you want marketing inside your CRM?

Klaviyo

Buyers run it beside a separate CRM; one added HubSpot because its Klaviyo setup did not cover its quote-based sales workflows.

HubSpot

Marketing and CRM together is among its most-praised themes, and some consolidated onto it for that.

04

Is HubSpot already in your stack?

Klaviyo

Buyers with HubSpot in place describe it as the harder add-on to justify on price.

HubSpot

Buyers describe its pricing as split between good value and costs that climb with tiers.

How the operating conditions differ

Recurring situations in the corpus, and where the evidence concentrates in each:

Pressures visible in these interviews

The complaints these interviews carry sit on both sides: Klaviyo buyers describe price as lists grow and gaps outside consumer email and SMS; HubSpot buyers describe limits on data and segmentation, a weaker fit for consumer ecommerce, and costs that climb with tiers and add-ons.

The clearest distinction in these interviews is how companies using both divide the work. HubSpot is more often used for the CRM, the sales team and B2B email, while Klaviyo carries consumer email and SMS for the online store. Moves between them run both ways and in small numbers, and they follow the business model: toward Klaviyo for consumer ecommerce, toward HubSpot to keep marketing inside the CRM.

The purchasing question, as we read it rather than as buyers state it, is whether your consumer email needs a store-focused tool badly enough to justify a second platform beside the CRM. Klaviyo is discussed by far more buyers, so its side of this page rests on more accounts than HubSpot's.
