Selling to Klaviyo customers
Klaviyo is the leading email and SMS platform for e-commerce brands, especially on Shopify. Its customers are growth-focused direct-to-consumer brands that measure everything in revenue per message.
Written by the Data InfoMetrix research team · Updated October 2026
Who runs Klaviyo
Klaviyo customers are mostly direct-to-consumer and retail brands in fashion, beauty, home goods, food and beverage, health and wellness, many of them on Shopify. They range from small brands with a few thousand subscribers to well-known retailers running large loyalty and lifecycle programs.
Klaviyo pricing scales with the number of active profiles, so database size is a reasonable proxy for brand size and email spend.
Who to contact
Founders and Heads of E-commerce decide in smaller brands. In larger ones, the VP of Marketing or Head of Retention owns the budget, and CRM, email and lifecycle managers run Klaviyo daily. Agencies that specialize in retention marketing are also influential.
When Klaviyo accounts are ready to buy
Seasonal peaks such as Black Friday and Cyber Monday drive planning months ahead. Other triggers include launching SMS, a loyalty or subscription program, replatforming the store, expanding to new countries and hiring a first retention marketer.
How to segment and approach
Segment by e-commerce platform, product category and region, then by the apps around Klaviyo: reviews, loyalty, subscriptions and customer support. Brands running Klaviyo with Recharge, Yotpo or Gorgias have mature retention stacks.
Speak in revenue terms. Retention teams respond to clear improvements in conversion, repeat purchase rate and deliverability, and they like case-style examples from similar brands.
