About this calculator

Email is the most ROI-positive marketing channel for most businesses ($36-42 per $1 spent industry-wide). Typical funnel: 20-30% open rate (varies by industry, list quality), 2-5% CTR of opens, 2-5% click-to-buy conversion. Healthy revenue per send: $0.10-1.00. Underperforming lists below $0.05 — issues are usually list quality (old subscribers) or content fit.
