ActiveCampaign vs Omnisend: 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.

Omnisend was founded in Lithuania in 2014, growing out of an earlier email product called Soundest, and focuses entirely on online stores. It serves small and mid-sized ecommerce brands that want email, SMS and web push in one tool without the complexity of an enterprise suite. Its main integrations are Shopify, WooCommerce, BigCommerce, Wix and other store platforms, which sync customers, orders, products and browsing events into Omnisend automatically. That store data powers the core use cases: welcome series, browse and cart abandonment, order confirmations, post-purchase follow-ups, win-back campaigns and product launches. Omnisend competes most directly with Klaviyo, often pitching itself as easier and cheaper.

The product includes a drag-and-drop email builder with ecommerce blocks for products and discounts, prebuilt automation workflows, signup forms, popups and spin-to-win wheels, web push notifications, segmentation on shopping behavior and reporting on sales generated by each campaign. Pro plan users can add SMS through a separate credits subscription. Audience syncs push segments to Facebook Custom Audiences and Google Customer Match for ads. RFM analysis groups customers by how recently, how often and how much they buy, and churn prediction flags customers at risk. Conditional content shows different blocks to different subscribers, and a product recommender inserts items based on past purchases or recently viewed products.

Omnisend's strengths are its ecommerce focus, easy prebuilt automations, a usable free plan, built-in AI writing and segmentation, and lower starting prices than Klaviyo. Its weaknesses are SMS limited to Pro since May 2026, contact-based pricing that grows with your list, fewer advanced analytics than Klaviyo and less fit for non-ecommerce businesses. Klaviyo offers deeper data and predictive analytics for larger brands. Mailchimp suits general small businesses. Brevo is cheaper for high volumes. ActiveCampaign offers more flexible automations for service and B2B companies. Choose Omnisend if you run an online store and want strong email and SMS automation without a steep learning curve.
