Everything worth knowing, nothing that isn't.
How it works
You send a question (often a rating like 'Reply 1-5') and the recipient's reply arrives back through two-way SMS, routed to your application by a webhook for scoring. See /answers/what-is-two-way-messaging and /answers/what-is-a-messaging-webhook.
Why SMS suits surveys
High open rates and immediacy mean more responses, faster, than email — ideal for NPS, CSAT, and short pulse checks right after an interaction. See /products/two-way-sms.
Keep it short and consented
One or two questions maximize completion, and recipients must have opted in. Honour opt-out and keep it brief. See /answers/sms-opt-in-best-practices.
