Best Ecommerce Automation Tools: Brevo vs Klaviyo vs ActiveCampaign

Ecommerce success depends on one thing above everything else: smooth automation. When your store reaches growth mode, manual follow-ups, basic newsletters, and simple triggers are no longer enough. You need deeper workflows, behavior-based targeting, multichannel reach, dynamic product recommendations, and real-time customer insights. Among hundreds of tools in the market, Brevo, Klaviyo, and ActiveCampaign stand out as the strongest ecommerce automation platforms. But they are built for different scaling paths: Brevo focuses on multichannel automation and CRM, Klaviyo dominates with ecommerce data intelligence, and ActiveCampaign specializes in deep behavioral automation and segmentation. This detailed comparison helps you decide which automation tool is the right engine for your scaling store.

• running SMS and WhatsApp reminders
• timing offers based on browsing activity
• predicting purchase windows

Brevo, Klaviyo, and ActiveCampaign all offer these capabilities, but with different strengths and cost structures. Your choice impacts your long-term growth, customer retention, and operational efficiency.
