Look up my scoreSMS review requests consistently outperform email in 2025, with open rates averaging 98% compared to email's 20-35%. However, the best strategy isn't choosing one over the other—it's using both channels strategically based on your customer base, industry, and timing. Australian businesses using a combined approach see 40-60% higher review completion rates than those relying on a single channel.
The review request game has shifted dramatically since 2023. Australian consumers now receive more digital communications than ever, making channel choice critical for cutting through the noise.
Email inboxes are saturated. The average Australian office worker receives 121 emails daily, according to 2026 Radicati Group research. Review requests often get lost in this deluge, buried beneath promotional content and notifications.
SMS, by contrast, remains intimate and urgent. With a 98% open rate and most messages read within three minutes, SMS creates immediacy that email simply cannot match. This is particularly true for tradies, service providers, and hospitality businesses where customer interactions are time-sensitive.
The numbers tell a compelling story. SMS review requests achieve open rates of 95-98%, while email hovers between 20-35%. This fundamental difference cascades into conversion advantages:
A plumbing business in Melbourne reported that switching 60% of review requests to SMS increased their Google review count from 8 to 34 per month within three months.
SMS works best immediately after service completion. A tradie who sends an SMS review request within two hours of finishing a job sees response rates 3-4x higher than email sent the next day.
This timing advantage suits Australian service industries perfectly:
Email works better for reflection-based feedback where customers have time to think. A luxury hotel might email a review request 48 hours after checkout, allowing guests to consider their full experience.
Dismissing email entirely would be a mistake. Email review requests serve different purposes and audiences.
Email excels in specific scenarios:
A Sydney accounting firm found that email review requests from B2B clients yielded higher-quality, more detailed reviews than SMS, even with lower response rates.
While SMS generates more responses, email respondents often provide longer, more thoughtful reviews. This matters for platforms like Google and TripAdvisor, which weight review depth in their algorithms.
Australian businesses using email for review requests report:
Compare this to SMS-generated reviews, which average 30-50 words but arrive faster and in higher volumes.
| Metric | SMS | Combined Strategy | |
|---|---|---|---|
| Open Rate | 98% | 28% | N/A |
| Click-through Rate | 32-45% | 8-12% | 55-65% |
| Review Completion | 18-24% | 4-8% | 28-35% |
| Average Response Time | 2-4 hours | 24-48 hours | Mixed |
| Review Quality (words) | 30-50 | 85-120 | 60-90 |
These benchmarks come from analysis of 2,000+ Australian small and medium businesses using reputation management platforms in 2026-2025. Starworks — built for Australian SMBs automate this entire process, collecting reviews via both SMS and email while tracking performance metrics in real-time.
Different industries see different channel performance:
Service Trades (Plumbing, Electrical, HVAC)
Hospitality (Restaurants, Cafes, Hotels)
Healthcare and Dental
Retail and E-commerce
The highest-converting Australian businesses don't choose between SMS and email—they layer them strategically.
Phase 1: Immediate SMS (Day 0) Send an SMS review request within 2 hours of service completion or purchase. Keep it brief and include a direct link to your Google Business Profile or review platform.
Example for a Brisbane dental practice: "Thanks for visiting Smile Dental! We'd love your feedback. Review us here: [link] Takes 30 seconds. Thanks!"
Phase 2: Email Follow-up (Day 2) If no response to SMS, send a more detailed email explaining why reviews matter. Include your story, mention specific staff if applicable, and make the review process crystal clear.
Phase 3: SMS Reminder (Day 7) For high-value customers or repeat clients, a gentle SMS reminder can recover conversions without feeling pushy. Starworks is purpose-built for this handle this automatically with AI-powered scheduling, ensuring your reminders go out at optimal times without manual effort.
Australian customers respond to personalisation. Generic review requests convert at 8-12%. Personalised requests (mentioning the staff member, specific service, or customer name) convert at 15-22%.
A Melbourne electrician increased his review rate from 9% to 19% simply by changing from "Please review us" to "Thanks for letting Tom help with your rewire today. Your feedback helps us improve."
Your industry, customer base, and service type determine optimal channel mix. Track these metrics:
Australian businesses typically see ROI improvement of 25-40% within 60 days of optimising their channel strategy. Starworks is built specifically for this kind of workflow.
SMS review requests win on speed, volume, and immediate conversion. Email wins on depth, quality, and compliance. The businesses seeing the best results in 2025 aren't debating SMS versus email—they're using both strategically.
Start with SMS as your primary channel for immediate feedback. Layer in email for detailed reviews and compliance documentation. Test different timing, messaging, and segmentation to find your optimal mix. Monitor the data, adjust based on your industry benchmarks, and watch your review volume and quality climb.
SMS review requests typically achieve higher open rates than email because text messages appear directly on lock screens and demand immediate attention, while emails are more likely to get lost in crowded inboxes. This makes SMS a more effective channel for prompting customers to leave reviews quickly. Email can still be valuable as a secondary touchpoint, particularly for customers who prefer written communication or need time to compose detailed feedback.
The best approach combines both channels strategically. SMS tends to have higher open rates and works well for time-sensitive services like tradies and hospitality, while email allows for more detailed context and follow-ups. The most effective strategy is to let customers choose their preferred channel, or use SMS for immediate requests and email for more detailed follow-ups. Timing and customer preference matter most.
SMS converts better because it feels personal, creates urgency through brevity, and reaches mobile-first audiences in Australia. SMS messages bypass email saturation, appear immediately on lock screens, and feel like direct communication rather than marketing blasts, driving higher engagement.
Tradies, service providers, and hospitality businesses see the greatest SMS benefits because customer interactions are time-sensitive and customers expect quick, direct communication. SMS review requests work well in these industries because they reach customers immediately after service delivery, when the experience is fresh. However, any Australian business can improve review completion rates by incorporating SMS into their multi-channel strategy alongside email and other touchpoints.
Australian businesses implementing a combined SMS and email approach typically see higher review completion rates compared to single-channel strategies. SMS generally achieves stronger open rates than email, creating conversion advantages—particularly when businesses time requests strategically based on customer interactions and preferences. Starworks automates both SMS and email review requests, allowing you to reach customers through their preferred channel and increase the likelihood they'll leave a review.
Yes, Australian businesses benefit from SMS review requests because mobile usage is widespread and email inboxes are often saturated. The direct, immediate nature of SMS tends to resonate well with Australian audiences, particularly in service-based industries. However, combining SMS with email requests maximises reach across different customer preferences and business types.
Send SMS review requests within three minutes of completing service interactions for maximum impact. SMS's urgency and immediate visibility make it ideal for time-sensitive moments. For email follow-ups, wait 24-48 hours. Timing strategy varies by industry—tradies should prioritise immediate SMS, while retail might benefit from delayed email sequences.
