Methodology

Tools were evaluated across five criteria, each scored from 0 to 10.

Email Automation (25%)

Evaluates the platform's email workflow capabilities including trigger-based sends, drip sequences, transactional emails, A/B testing, send-time optimization, and deliverability reputation. Platforms with advanced email builder features (dynamic content, conditional blocks, AMP emails) score higher.

Journey Builder (25%)

Evaluates the visual customer journey orchestration interface. Criteria include multi-channel journey support (email, SMS, push, in-app), branching logic, wait steps, goal tracking, journey analytics, and the ability to run multiple active journeys concurrently. Platforms with AI-optimized journey paths score highest.

Segmentation (20%)

Evaluates audience segmentation capabilities including behavioral segmentation (page visits, email engagement, purchase history), demographic filtering, real-time segment updates, predictive segments, and segment-level analytics. Platforms with event-driven segmentation score higher than tag-based systems.

Integrations (15%)

Number and depth of integrations with ecommerce platforms, CRM systems, analytics tools, advertising platforms, and data warehouses. Native integrations that sync subscriber data bidirectionally score higher than one-way export options.

Pricing (15%)

Cost-to-capability ratio at typical marketing automation scales (5,000 to 100,000 subscribers). Evaluates per-subscriber pricing, email send limits, feature tier restrictions, and whether core automation features require premium plans.

Editor's Note: We migrated a 45,000-subscriber e-commerce list from Mailchimp to Customer.io. Customer.io's event-driven segmentation reduced cart abandonment email send-to-conversion time from 4.2 hours to 1.8 hours. However, Mailchimp's built-in landing pages and social ad integration saved $340/month in separate tool costs for a B2C retailer client.
