Reach people where they actually answer — on SMS, WhatsApp, and phone
Email surveys have an obvious problem: people don’t open email fast, and they don’t open it at all below a certain age bracket. SMS, WhatsApp, and voice reach the same people through channels they actually respond to. Connecting Responsly to Twilio opens those channels without leaving the survey platform.
Where Twilio-delivered surveys pay off
Post-interaction CSAT for phone-first audiences
Call centers handling retail, telco, and consumer finance often serve audiences that read email rarely. An SMS CSAT survey sent minutes after the call ends routinely hits 35%+ response rates — three times what the email channel produces.
WhatsApp for international programs
In regions where WhatsApp is the primary consumer messaging channel (LATAM, South Asia, parts of Europe), WhatsApp-delivered surveys capture audiences that simply don’t reply to email. Responsly + Twilio’s WhatsApp Business API makes this straightforward.
Appointment and service follow-up
Clinics, salons, auto shops, field service — any appointment-based business benefits from an SMS follow-up. “How was your appointment? Reply with a score 1-5.” Simple, fast, and customers actually answer.
Event and conference attendee feedback
During and after events, a Twilio SMS reaches attendees instantly. Real-time session feedback or post-event NPS both work well; email simply can’t compete for response timing at events.
Voice IVR for transactional feedback
Some audiences — older demographics, certain B2B workflows — still respond best to automated voice follow-ups. Twilio’s Voice API plus Responsly’s survey logic handles this end to end.
Multi-channel fallback
Send by email; if no response in 48 hours, follow up by SMS. This two-stage approach maximizes total response rate while keeping SMS volume manageable. Automatic deduplication prevents double responses.
Connecting Responsly to Twilio
- Create an API Key in your Twilio console (preferable to Account SID/Auth Token for security).
- Paste credentials into Responsly’s Twilio integration settings.
- Pick the channel(s) per survey — SMS, WhatsApp, voice.
- Configure the message content. For SMS, keep it under 160 characters. For WhatsApp, follow template rules for initial outreach.
- Set delivery triggers. Post-event, post-interaction, scheduled, event-based.
- Map identifiers. Customer ID, interaction ID, and any other hidden fields needed for response attribution.
- Test with a live number before going live.
Practices that keep SMS/WhatsApp surveys effective
Short beats long every time. One question over SMS, followed by an optional open-ended reply. Anything longer drops response rates fast.
Respect opt-out rules. STOP/UNSUBSCRIBE must be honored; Twilio enforces this by default. For regulated markets (US, UK, EU), confirm legal compliance for your use case.
Send at the right local time. 10 AM local beats 3 AM local. Responsly’s timezone-aware sending should be configured per audience segment.
Include brand identity. Recipients should know who’s asking. A short “From {Brand}:” prefix beats an anonymous number.
Monitor per-channel response rates. SMS may win on rate but cost more per response; email may win on economics for low-volume programs. Track both and choose per-program.
Pair with a CRM. Survey scores should land on the customer record. See Salesforce, HubSpot, or Zendesk for the CRM/helpdesk side.
Reach audiences email can’t
Connect Responsly to Twilio and surveys find customers on the channels they actually answer. SMS for speed, WhatsApp for international reach, voice for accessibility — one platform, one reporting view, response rates that make email look quaint.
