We have added this comparison page for email marketing services about 6 months ago and wonder how helpful is it to someone looking for their new/next email marketing provider. The space is highly competitive with 300+ providers, so it's not really feasible to do something more comprehensive. What do you think of my provider selection and grouping providers by specialty/niche? Are there any important features missing from comparison table? Should I add E-commerce section - thinking of Klaviyo and Constant Contact for it, any other providers that are leaders in Ecommerce niche?
