Customer Thermometer review and pricing

UK-built one-click email CSAT and NPS for non-technical buyers wanting embed-in-email simplicity.

By Customer Thermometer Limited · Founded 2010 · Oxford, UK · private

Customer Thermometer is the UK-built one-click email CSAT and NPS platform, founded 2010 in Oxford. Privately-held, founder-led, with deep installed base across UK SMB and global support teams. The product centers on one-click email feedback (a four-button image embedded directly in email signature or transactional email), with simple closed-loop alerting and basic reporting. Strengths: simplest setup in the category (no respondent landing page, single-click response in email client), strong UK and EU presence, GDPR-native compliance (UK Oxford-hosted), transparent SMB pricing, and founder-led stable execution since 2010. Best fit for non-technical buyers wanting embed-in-email simplicity for support CSAT, internal team feedback, or simple NPS without survey complexity. Trade-offs: dramatically less feature depth than Delighted, AskNicely, or Retently (no advanced segmentation, no in-app widget, limited text analytics, no AI), pricing scales fast at higher contact volumes, integrations limited (about 20 vs Delighted 40), and not a fit for structured NPS programs at mid-market or enterprise scale.
