How to Choose the Right Survey Method

Consider these five factors when choosing your survey method:

  1. Technical ability of your target audience — Are they comfortable with digital surveys?
  2. Required sample size — Email and SMS reach thousands; focus groups reach dozens.
  3. Research duration — Online surveys return results in days; telephone research takes weeks.
  4. Budget — Online surveys cost a fraction of telephone or in-person research.
  5. Available infrastructure — Do you have email lists, phone numbers, or app users to survey?

For most customer feedback programs (NPS, CSAT, CES), email surveys and in-app pop-ups hit the best balance of reach, cost, and response rate. Adding SMS or WhatsApp for post-delivery surveys can double your response rate in mobile-first markets.
