What matters in an SMS survey setup

SMS gets read. That is why teams reach for Twilio. The hard part is everything around the message: US carrier registration (A2P 10DLC), opt-outs, per-message costs, and somewhere to store and analyze the answers.

Compare tools on how much of that they handle for you, whether people answer by text or on a linked form, what each message really costs, and how private the responses are.

The 5 tools at a glance

1. BlockSurvey: best for no-code SMS surveys on Twilio

BlockSurvey text campaigns send your survey link by SMS through Twilio, so you get Twilio delivery without writing code or managing a Twilio account yourself. You upload contacts, write the message and send.

US sending needs A2P 10DLC registration, and BlockSurvey collects the verification details in the app and submits them through Twilio. Approval typically takes one to two weeks. Responses are end-to-end encrypted, and AI analysis sums up open-text answers.

• Best for: Teams that want SMS survey distribution through Twilio without building anything.
• Cons: Respondents answer on a linked survey page rather than by replying to the text, and US sending waits on 10DLC approval.
• Price: Free plan; paid plans from $49/mo ($39/mo billed yearly). SMS credits are $0.04 each, sold in bulk from 10,000.

2. Twilio Studio: best for custom reply-by-text survey flows

Twilio Studio is Twilio's visual flow builder. You can build a survey where people answer each question by replying to the text, with branching based on their answers. Twilio publishes a sample SMS survey flow to start from.

You own the rest: storing responses, reporting, opt-out handling and carrier registration.

• Best for: Developers who want reply-by-text surveys built into their own systems.
• Cons: No survey reporting out of the box, and setup and upkeep fall on your team.
• Price: Twilio per-message pricing plus carrier and registration fees.

3. SurveySparrow: best for conversational SMS for CX teams

SurveySparrow sends surveys by SMS alongside email, web and WhatsApp, and its conversational format reads well on a phone. Recurring NPS and CSAT surveys are easy to schedule.

SMS distribution is tied to paid plans and credits.

• Best for: CX teams running recurring NPS and CSAT by text.
• Cons: SMS is a paid add-on, and responses are not end-to-end encrypted.
• Price: Paid plans; SMS credits priced separately.

4. SurveyMonkey: best for familiar tool with SMS collection

SurveyMonkey offers an SMS collector in supported regions that texts a survey link to your contacts. If your team already uses SurveyMonkey, it is the least effort.

SMS sending is limited to certain regions and plans.

• Best for: Existing SurveyMonkey customers who want to add text distribution.
• Cons: Regional and plan limits on SMS, and higher tiers needed for many features.
• Price: Paid plans; SMS availability depends on plan and country.

5. Qualtrics: best for enterprise SMS feedback programs

Qualtrics supports both two-way SMS surveys and SMS invites to web surveys, with deep reporting and integrations for large CX programs.

It is priced and implemented as an enterprise platform.

• Best for: Large organizations running SMS feedback across many locations.
• Cons: Quote-based pricing and a long setup compared with lighter tools.
• Price: Quote-based enterprise contracts.

Which should you pick?

If you want Twilio delivery without building a Twilio app, BlockSurvey is the practical choice: $0.04 per SMS, 10DLC registration handled in the app, and encrypted responses. If you need people to answer by replying to the text and you have developers, build it in Twilio Studio.

Skip BlockSurvey if reply-by-text answers are a hard requirement.
