ROI Math by Industry
Average across industries: $42/$1 spent. B2B SaaS: $36/$1. E-commerce: $42/$1. Retail: $36/$1. Travel: $51/$1. Subscription: $45/$1. Consumer goods: $39/$1. Most underestimate ROI because they don't track end-to-end attribution.
Optimization Levers
(1) List quality: clean inactive subscribers quarterly. (2) Segmentation: send relevant content to right audience (3-5x lift). (3) Automation: behavior-triggered sequences (welcome, cart abandonment, upsell). (4) Personalization: name, behavior-based content. (5) Mobile optimization: 60%+ open on mobile.
Cost Considerations
Platform fees scale with list size. Mailchimp/HubSpot: $50-$500/mo for 10K-50K. Klaviyo: variable. Active list maintenance: hire VA for segmentation, design. Templates + tools (Canva, ChatGPT for copywriting): minimal extra cost.
