ActiveCampaign vs Klaviyo: pricing, features and which to choose

ActiveCampaign was founded in 2003 by Jason VandeBoom in Chicago, beginning as a consulting firm and software vendor before relaunching as a cloud email marketing and automation platform. It became one of the most popular automation tools for small and mid-sized businesses, ecommerce stores, coaches, agencies and B2B companies that outgrow basic newsletters but do not want an enterprise suite. It is known for its visual automation builder, which lets marketers design multi-step journeys triggered by actions such as signups, purchases, page visits or email clicks. It integrates with hundreds of apps, including Shopify, WooCommerce, Salesforce, WordPress and Zapier.

Core features include email campaigns with more than 250 templates, a drag-and-drop designer, forms, landing pages, site messages, web push, SMS and WhatsApp add-ons, website and event tracking, and A/B testing. Automations branch on conditions, wait for goals, update contact fields and hand leads to sales. Segmentation, lead scoring, conditional content that changes an email for each contact, and attribution reporting grow with each plan. An optional Enhanced CRM add-on provides sales pipelines, deal tracking and sales engagement. Ecommerce integrations sync orders and products for abandoned cart and post-purchase flows. Transactional email is available as a paid add-on.

ActiveCampaign's strengths are its flexible automation builder, deep segmentation, strong integrations, predictive features and AI builders that speed up campaign setup. Its weaknesses are prices that climb quickly with contacts, a CRM sold separately, a learning curve for advanced automations and no free plan. Mailchimp is easier for beginners and has a free tier. Klaviyo is stronger for ecommerce data and SMS. HubSpot combines marketing with a full CRM at higher cost. Brevo charges by emails sent rather than contacts, and Kit targets creators. Choose ActiveCampaign if automation depth matters more than simplicity for your business.

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.
