Frequently Asked Questions
What is the average SMS open rate in 2026?
The average SMS open rate is 95–98% in 2026, with 90% of messages read within 3 minutes of delivery, according to Klaviyo’s 2025 SMS Benchmark Report and the Mobile Marketing Association’s 2025 data. Promotional SMS open rates are slightly lower at approximately 92%, while transactional SMS (order confirmations, shipping alerts) achieve 98%+. These figures represent a 4–5x higher open rate than email’s 21.33% average.
What is the ROI of SMS marketing compared to email?
SMS marketing achieves an average ROI of $71 per $1 spent vs. email’s $42 per $1, according to Klaviyo’s 2025 data. However, the cost per send for SMS ($0.01–$0.05) is significantly higher than email ($0.0001–$0.001), which affects total campaign economics at scale. The highest ROI approach in 2026 is combining SMS and email in multichannel automation — brands using both channels together achieve 47% higher revenue per subscriber than email-only brands.
What email deliverability rate should I target in 2026?
Target an inbox placement rate (deliverability rate) of 90%+ in 2026. The overall industry average is 84.2%, so achieving 90%+ puts you above average. To reach 90%+: implement SPF, DKIM, and DMARC authentication on your sending domain; maintain list hygiene by removing hard bounces immediately and inactive subscribers quarterly; keep spam complaint rates below 0.08% (Google’s threshold before sending restrictions); and warm up new IPs gradually rather than immediately sending at full volume.
How do I get SMS opt-ins for marketing?
The most effective SMS opt-in strategies in 2026 are: checkout opt-in prompts (18–24% conversion rate), pop-up forms with SMS-specific incentives like “Text to get 15% off” (improve opt-in by 68%), keyword campaigns (“Text DEALS to 12345”), and post-purchase thank-you pages. All SMS opt-ins must be explicit and documented for TCPA compliance — pre-checked checkboxes or bundling SMS consent with email consent are not compliant. CampaignOS includes built-in SMS opt-in form templates with TCPA-compliant consent language.
How often should I send marketing SMS messages?
The optimal marketing SMS frequency is 2–4 messages per month per subscriber, according to Attentive’s 2025 SMS Marketing Benchmark Report. Above this frequency, opt-out rates increase significantly — brands sending 8+ SMS/month see opt-out rates 2.4x higher than brands sending 2–4/month. Triggered SMS (abandoned cart, price drop alerts, win-back) can be sent outside this broadcast frequency without increasing opt-outs because they are highly relevant to individual recipients. The key principle: every SMS should provide clear, immediate value to the recipient or risk opt-outs.
