What is Channel ROI Comparison?
An email vs SMS marketing comparison evaluates the cost, reach, engagement, and conversion potential of each channel for your specific audience.
The Formula
Channel ROI = (Revenue from Channel − Channel Cost) ÷ Channel Cost × 100
Worked Example
A retailer: email costs $500/month reaching 10,000 subscribers generating $8,000. SMS costs $800/month reaching 3,000 generating $5,000.
- Email ROI: ($8,000 − $500) ÷ $500 × 100 = 1,500%
- SMS ROI: ($5,000 − $800) ÷ $800 × 100 = 525%
- Email revenue per contact: $0.80
- SMS revenue per contact: $1.67
📌 Email has higher total ROI but SMS generates 2x more revenue per contact — best strategy uses both channels.
Why This Matters
Channel diversification
Relying on one channel is risky. Businesses using both email and SMS see 25% higher overall marketing ROI.
Audience preferences
75% of consumers want to receive offers via SMS, but 80% also check email daily. Meet customers where they are.
Use case optimization
SMS excels at time-sensitive offers (98% open rate). Email excels at detailed content. Using the right channel for each message improves results.
Common Mistakes
❌ SMS for long content
SMS is for brief, urgent messages. Detailed content belongs in email where formatting and links work better.
❌ Same message on both channels
Each channel has different strengths. Adapt messaging format and length to the channel.
❌ Ignoring opt-in compliance
SMS has stricter consent requirements than email. Violating regulations risks $500K+ fines under TCPA.
