CSAT Survey in Email Signature

A CSAT or NPS survey in an email signature is an inline one-click satisfaction rating control embedded in the signature, typically used by customer support, customer success, or account management teams. The recipient sees a 1-to-5 star scale, a thumbs up or down, or an NPS 0-to-10 score embedded in the signature; clicking any value records the rating and optionally opens a follow-up form. Because the survey is present on every support ticket reply or customer-facing email without requiring a separate survey email, response rates are dramatically higher than dedicated survey campaigns. Implementations vary: some platforms host the survey at a destination URL and pass the response as a query parameter; others embed the survey UI directly in the signature using HTML hover states (with degraded fallback in clients that strip styles). The captured ratings flow into helpdesk tools (Zendesk, Intercom, Freshdesk) or a dedicated CSAT analytics view.
