Email marketing remains the highest-ROI digital channel at $36-42 per $1 spent. The right platform depends on your business model: e-commerce brands need deep integration with Shopify and behavioral triggers (Klaviyo), creators need simple automation and deliverability (ConvertKit), and general SMBs benefit from easy-to-use all-in-one platforms (Mailchimp). Key differentiators include automation sophistication, segmentation depth, deliverability rates, and pricing model (by subscribers vs. by emails sent).
We test email platforms by running identical campaigns, measuring deliverability across Gmail, Outlook, and Yahoo, evaluating automation builder complexity, analyzing reporting depth, and benchmarking customer support response times. We also survey 500+ real users of each platform annually.
