What are SMS surveys?

Think of SMS surveys as your shortcut to instant feedback. Unlike email forms or web questionnaires that often go ignored, SMS surveys deliver one simple question—or a short series—directly to the recipient’s phone as a text message. The customer replies by SMS, and you receive their input instantly, in a format that’s easy to analyze. This makes SMS a quick and easy solution for gathering feedback on any product or service.

How do SMS surveys work?

• You create a message survey (or short series) asking for feedback, a rating, or an NPS score.
• Send the survey via SMS to your audience, using a platform like Infobip, Twilio, or another CPaaS provider.
• Recipients reply by sending a text—their answers are recorded, organized, and ready for action, often in real time.

Why not just use email or web forms?

• SMS surveys nearly always land in the recipient’s main inbox—no algorithms, no spam folder, no Wi-Fi required.
• Responses typically arrive within minutes instead of hours or days.
• SMS feels personal. It’s often read and acted on immediately, making it ideal for time-sensitive feedback like post-purchase satisfaction, appointment follow-ups, or lead qualification.

Benefits of SMS surveys

Leading brands are turning to SMS surveys to get high-quality feedback, fast, from almost any customer segment. Here’s why they work so well.

Sky-high open and response rates

SMS surveys get opened 98% of the time. Typical response rates range from 40–60%, far exceeding email’s 10–30%. These high open rates directly boost data accuracy for customer satisfaction surveys.

Infobip clients like Wefarm achieved a 97% response rate with two-way SMS surveys.

Real-time feedback when it counts

Want feedback seconds after an interaction? SMS surveys prompt near-instant responses.

In industries like retail, travel, and healthcare, this speed helps resolve issues early or recognize successes as they happen, especially helpful for any customer service or support team.

Universal reach and simplicity

Anyone with a mobile phone can respond, no app or internet needed. Infobip’s infrastructure reaches users in 190+ countries.

For teams with diverse global audiences, text message surveys are one of the most inclusive feedback tools available.

Cost and resource efficiency

No design work, app development, or logins—just write your message and send.

Automation delivers real-time analytics, reducing manual effort. You can send your surveys to thousands with minimal time and cost using an SMS survey tool.

Consistency and brand control

Marketing teams can use branded SMS templates to maintain consistency.

Platforms like Infobip Moments sync responses into your overall customer or campaign view, enabling consistent reporting on customer loyalty, satisfaction, or net promoter score NPS.

Crafting effective SMS surveys with Infobip Moments

With Infobip Moments, building SMS surveys is simple, scalable, and fully automated from the first message to your analytics dashboard.

1. Use the drag-and-drop builder: Create SMS campaigns in minutes. Choose a template (NPS, CSAT, lead qualification, appointment feedback) or build your own. Infobip supports multiple choice, open-ended, and rating-based types of surveys.
2. Personalize with customer data: Use Infobip People to dynamically insert names, purchase details, or custom questions.
   Trigger surveys based on behavior (e.g., after a purchase or support ticket).
3. Automate delivery and reminders: Schedule surveys, run A/B tests to find the best timing, and send automated reminders.
   Use omnichannel fallback (WhatsApp, Viber, email) if SMS isn’t delivered. Include a survey link in your messages if you need longer forms or web-based data capture.
4. Aggregate & analyze automatically: Responses flow into real-time dashboards—track NPS, sentiment, and export to CRM or analytics tools. Infobip automation manages opt-ins/opt-outs and compliance, protecting your team.
   Integrated marketing managers can sync survey results across channels for a unified, actionable view—no more feedback silos.

Best practices for SMS surveys

SMS surveys are effective, but execution matters. Here’s what high-performing teams do differently.

• Keep surveys short and clear: Limit to one question or up to five. The simpler the ask, the higher the completion rate.
• Time it right: Send surveys immediately after key events—like purchases or support interactions. Use A/B testing to find optimal timing.
• Personalize and segment: Use names and context to increase relevance. Trigger surveys based on individual customer behavior or product or service interactions.
• Limit frequency: Avoid survey fatigue. Platforms like Infobip Moments let you set limits (e.g., one per quarter).
• Comply with data privacy and opt-ins: Get explicit consent. Offer easy opt-outs. Use a compliant provider to stay aligned with GDPR, TCPA, and local laws.
• Consider incentives—carefully: Offers can improve participation but should not be tied to positive feedback only.

Real-world examples of SMS surveys

Examples show the value of SMS surveys in action. Here are some templates and business use cases.

Templates

NPS

Why it works:
This is a standard Net Promoter Score (NPS) question. It’s simple, quantitative, and instantly familiar to most recipients. It helps you measure customer loyalty with one clear metric that’s easy to benchmark over time.

Delivery feedback

Why it works:
A binary response format keeps it quick and easy. It targets a specific part of the customer journey and helps identify operational or logistics issues immediately.

Appointment feedback

Why it works:
A 1–5 scale gives more nuance than a yes/no question but is still simple to answer by SMS. It captures satisfaction in real time, allowing the support team or service provider to follow up if needed.

Event rating

Why it works:
It collects immediate post-event impressions while the experience is fresh. The scale allows for quick aggregation of customer satisfaction and can flag areas needing improvement.

Lead qualification

Why it works:
This multiple choice format streamlines qualification. It segments interest levels without requiring back-and-forth, helping your support team or sales team prioritize leads efficiently.

Use cases

• Healthcare: Hospital Alemão Oswaldo Cruz used SMS appointment reminders and satisfaction surveys to reduce patient response time by 63% and increase check-ups by 82%.
• Ecommerce: Retailers trigger NPS and customer satisfaction surveys post-delivery for fast feedback and issue resolution.
