Guessing what your customers think is expensive. An SMS survey at the right moment —after a purchase, a delivery or a support chat— gives you an honest, direct answer, and it's almost always read. With NotifyBulk surveys you measure NPS and CSAT and collect feedback without forms nobody fills out.

Why survey by SMS
Email surveys have a problem: low open and response rates. SMS is read within minutes, so a short survey sent at the right moment gets far more real feedback. It's the ideal channel for taking the pulse of the experience while it's still fresh.
The 5 question types
The survey builder lets you mix formats depending on what you want to measure:
| Type | What it's for |
|---|---|
| Rating (1–5 or 1–10) | Satisfaction scores — ideal for NPS and CSAT |
| Yes / No | Quick binary answers |
| Multiple choice | The customer picks from a list |
| Number | Numeric input |
| Free text | Open-ended comments |
For each question you set the text, whether it's required and the order (drag to reorder). You add a welcome message at the start and a thank-you message at the end.
How it's sent and how customers respond
Surveys are distributed by SMS:
- Open the survey and click Send.
- Pick the contact group that receives it.
- The welcome message and first question are sent by SMS.
From there the conversation flows on its own: each customer answer automatically triggers the next question, all the way to the thank-you message. For the customer it's as simple as replying to a chat.
Reports: what you measure
In the survey reports you see:
- Total respondents and completion rate.
- Per-question breakdown to read results at a glance.
- Individual responses per contact, and a respondents list with status (in progress / completed) and dates.
- CSV export to analyze or share.
Tips for more responses
- Short wins: 3 to 5 questions have the best completion rates over SMS.
- Use rating for NPS or CSAT and leave an optional free text for the "why".
- Right moment: send when the customer is likely available (avoid early morning or late night).
- Close the loop: follow low scorers with an automated campaign or a personal reply.

Why measure satisfaction with SMS surveys?
Because SMS is almost always read, and within minutes, so SMS surveys tend to get better response rates than email ones. It's ideal for measuring NPS or CSAT right after a purchase or support interaction.
What question types can I use?
Free text, number, rating (1–5 or 1–10 scale), multiple choice and yes/no. Rating is perfect for NPS and CSAT scores.
How does the customer respond?
Conversationally: the welcome message and first question are sent by SMS, and each answer automatically triggers the next question until it's done.
Can I export the results?
Yes. In the reports you see total respondents, completion rate and the per-question breakdown, and you can export all responses to CSV.
