SMS has higher per-message costs than email but often higher conversion rates. This calculator helps you determine whether the higher cost is justified by comparing revenue per message and ROI against your other channels. Having a precise figure at your fingertips empowers better planning and more confident decisions. Manual calculations are error-prone and time-consuming; this tool delivers verified results in seconds so you can focus on strategy.
SMS CR (%) = (Orders from SMS / SMS Delivered) × 100 Revenue per SMS = Total Revenue / SMS Delivered SMS ROI = (Revenue − Total SMS Cost) / Total SMS Cost × 100
Result: 1.50% SMS conversion rate
With 5,000 SMS delivered and 75 orders at $90 AOV, the SMS CR is 1.50%. Revenue = $6,750. Cost = 5,000 × $0.015 = $75. ROI = ($6,750 − $75) / $75 = 8,900%. Revenue per SMS = $1.35.
SMS marketing generates an average of $71 per subscriber annually for e-commerce brands, according to industry data. While the list is smaller than email (typically 10–30% of email list size), the per-subscriber value is 2–3× higher due to superior engagement.
Abandoned cart reminders (highest CR), flash sale announcements (best for urgency), restock notifications (for high-demand items), shipping updates (builds trust), and loyalty point reminders (drives repeat purchases). Start with cart recovery and shipping, then expand to promotional.
The most effective approach combines both channels. Send an email first, wait 2–4 hours, then follow up with SMS to non-openers. This multi-touch strategy captures attention across both channels and typically outperforms either one alone by 20–40%.
Promotional SMS campaigns convert at 0.5–2%. Abandoned cart SMS converts at 2–5%. Flash sale alerts and restock notifications can reach 3–8%. The average across all SMS types is approximately 1–2%.
SMS has higher open rates (98% vs. 20–25%) and faster action (read in 3 minutes vs. hours). However, SMS costs more per message ($0.01–$0.05 vs. fractions of a cent). Both channels should be used complementarily.
In the US, SMS costs range from $0.01 to $0.05 per message depending on your provider (Twilio, Attentive, Postscript). MMS with images costs more. International rates vary significantly.
For most stores, yes. The high engagement rates and immediacy make SMS ideal for time-sensitive promotions, cart recovery, and shipping updates. Start with abandoned cart SMS and expand from there.
Limit frequency to 4–8 messages per month. Only send genuinely valuable content (exclusive deals, restock alerts, order updates). Every irrelevant message risks an opt-out. Quality over quantity.
In the US, TCPA requires explicit written consent before sending marketing SMS. Violations carry penalties of $500–$1,500 per message. Always use double opt-in and maintain clear records of consent.
