Braze vs Klaviyo: pricing, features and which to choose

Braze was founded in 2011 in New York as Appboy by Bill Magnuson, Jon Hyman and Mark Ghermezian, starting with mobile app messaging before renaming in 2017 and expanding across channels. It went public on Nasdaq in 2021 under the ticker BRZE. Its customers are consumer brands in retail, media, travel, finance, gaming and food delivery with large mobile and web audiences, and CDP.com reported that Braze had 2,789 customers in its second quarter of fiscal 2027. Braze competes with Iterable, Salesforce Marketing Cloud, Adobe Journey Optimizer and Klaviyo at the upper end, and is known for real-time, event-driven messaging at very large scale.

Canvas is Braze's visual journey builder, with branching logic, waits, experiments and triggers based on user behavior or schedules. Messages go out natively across email, mobile and web push, SMS, MMS, RCS, WhatsApp, in-app messages, content cards and webhooks from one interface. The Braze Data Platform ingests events from apps, websites and data warehouses such as Snowflake, and Currents streams engagement data back out. Liquid templating and catalogs personalize content for each user. Intelligent Timing picks the best send time per user and Intelligent Selection shifts traffic toward winning variants. Predictive features forecast churn and purchases, and dashboards report on revenue and retention.

Braze's strengths are real-time messaging at very large scale, broad native channels including mobile push and in-app, a flexible journey builder, deep data integrations and AI that ranges from an assistant to self-learning decisioning. Its weaknesses are high cost, quote-only pricing, the need for engineering support to implement and a platform far beyond what small businesses require. Iterable is a similar cross-channel rival. Salesforce Marketing Cloud and Adobe Journey Optimizer suit companies already using those suites. Klaviyo serves ecommerce brands at lower cost. Choose Braze if you run a large consumer app or brand that needs personalized, real-time messaging across many channels.

Klaviyo is a B2C CRM and ecommerce marketing platform founded in 2012 by Andrew Bialecki and Ed Hallen. The company says more than 205,000 brands use its products, and it trades publicly on the New York Stock Exchange under KVYO. Its catalog includes email, mobile messaging, Reviews, Customer Hub, Helpdesk, Customer Agent, Composer, Data Platform, and Analytics. That range makes Klaviyo broader than an email sender, although ecommerce marketing remains its clearest center. Its strongest identity is a customer data and automation system for brands that sell directly to consumers online. The company says it began as a customer database, added email marketing in 2013, SMS in 2021, Reviews and a CDP in 2023, and a unified B2C CRM in 2025.

Klaviyo connects an online store and other first-party sources, then unifies customer profiles with behavioral events. Teams build segments, campaigns, and event-triggered flows, send through email or mobile channels, and measure revenue attribution. Klaviyo lists Shopify, Salesforce Commerce Cloud, and WooCommerce integrations, while its 2024 filing described more than 350 integrations as of 2023. Typical journeys include abandoned-cart reminders, post-purchase messages, replenishment prompts, and targeted promotions. Product activity and predictive analytics can influence audience selection and send timing. The system depends on clean event data and thoughtful profile design, making implementation more demanding than a basic newsletter tool. Marketers can connect browsing, purchase, engagement, and service signals to coordinated messages, then examine reported revenue.

Klaviyo’s limits are operational as well as financial. Reachable-profile growth can increase recurring costs, while separately billed products make the total harder to estimate than a single-channel plan. Its AI features require customer review, and necessary prompts or data may be sent to providers to generate requested outputs. Klaviyo says provider contracts prohibit global-model training on customer data, while its policy describes controls that depend on applicable products, settings, contracts, and provider terms. Mailchimp is broader for general small-business marketing, ActiveCampaign is a close automation alternative, and Omnisend also targets ecommerce brands. Klaviyo offers deeper behavioral ecommerce segmentation and revenue attribution than many newsletter-focused tools, but requires better data discipline and a larger budget as reachable profiles grow. Pick Klaviyo when behavioral ecommerce data, profile-based journeys, and revenue reporting matter more than the lowest setup cost.
