As of April 2026, ConvertKit serves over 600,000 creators. The platform's visual automation builder enables tag-based subscriber journeys triggered by form signups, link clicks, product purchases, and custom events.

The Creator plan ($29/month for 1,000 subscribers) includes automation, landing pages, and commerce.

Deliverability (25%)

Evaluates inbox placement rates for both transactional and marketing emails. Criteria include SPF/DKIM/DMARC configuration support, dedicated IP availability, bounce management, suppression list handling, ISP feedback loops, and third-party deliverability audit results. Platforms with published inbox placement rates above 95% score higher.

Automation Depth (25%)

Evaluates the sophistication of email workflow automation. Criteria include trigger types (behavioral, time-based, event-driven), branching logic, A/B testing within flows, send-time optimization, multi-channel sequencing (email + SMS + push), and the ability to run concurrent automated journeys. Platforms with AI-optimized send timing score highest.

Templates (20%)

Evaluates the quality and variety of email templates and the drag-and-drop editor. Criteria include pre-built template count, responsive design quality, dynamic content blocks, conditional content sections, AMP email support, and code-level template customization. Platforms with 100+ modern, mobile-optimized templates score higher.

Analytics (15%)

Evaluates reporting and analytics capabilities. Criteria include open/click tracking, revenue attribution, cohort analysis, campaign comparison dashboards, predictive analytics (predicted lifetime value, churn risk), and deliverability monitoring dashboards.

Pricing (15%)

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