How much do businesses spend on Klaviyo?

The chart below illustrates average quarterly spend on Klaviyo across different business sizes.

Micro businesses demonstrate steady growth in their Klaviyo spending throughout the year, with modest increases from quarter to quarter culminating in notable growth by year-end. This gradual upward trend suggests these organizations are expanding their e-commerce marketing efforts and discovering additional value from Klaviyo's features as they scale their online businesses.

Small and medium-sized businesses show consistent spending patterns with accelerating growth in the latter half of the year. After maintaining relatively stable investment through the first two quarters, these organizations increased their Klaviyo expenditures more substantially in the final quarters. This pattern likely reflects seasonal e-commerce trends and growing sophistication in email marketing automation as these businesses optimize their customer acquisition and retention strategies.

Mid-market and enterprise organizations exhibit the most dramatic spending fluctuations, starting with peak investment in the first quarter before experiencing a significant decline through mid-year, followed by steady recovery. This volatility might indicate large-scale implementations with substantial upfront costs, followed by optimization periods, and renewed investment as these organizations expand their marketing automation capabilities.

Who is Klaviyo best for?

The chart below breaks down Klaviyo's user base by industry and business size.

Micro businesses represent nearly half of Klaviyo's user base, demonstrating the platform's strong appeal to emerging e-commerce entrepreneurs and small online retailers. This substantial representation demonstrates Klaviyo's effectiveness in serving businesses that require sophisticated email marketing capabilities without the complexity or pricing barriers typically associated with enterprise-level solutions.

Small and medium-sized businesses constitute over one-third of the platform's customer base, indicating Klaviyo's success in serving growing e-commerce companies that require more advanced segmentation and automation features as they scale. Mid-market and enterprise companies comprise the smallest segment, accounting for under fifteen percent of users. However, their significantly higher spending levels suggest that they contribute meaningfully to overall platform revenue.

This distribution reveals Klaviyo's positioning as an accessible yet powerful e-commerce marketing platform, with over four-fifths of users coming from smaller business segments. The platform appears particularly effective at attracting online retailers in their growth phases, making it an attractive option for e-commerce businesses planning to scale their marketing sophistication and revenue over time.
