Summary
The prevalent consensus, supported by legal documentation (CAN-SPAM, GDPR), email marketing best practices, and expert opinions, strongly advises against requesting extra information like CAPTCHAs during the unsubscribe process. The emphasis is on ensuring a simple, frictionless, and easily accessible unsubscribe experience. CAN-SPAM explicitly limits required information to the email address and opt-out preferences, while GDPR mandates that withdrawing consent should be as easy as giving it. CAPTCHAs, while sometimes used to prevent bot abuse, are generally discouraged due to the potential for user frustration. One-click unsubscribe options and clearly visible unsubscribe links are recommended. Preference centers offer an alternative by allowing users to tailor their email subscriptions, potentially reducing overall unsubscribe rates. Difficult unsubscribe processes negatively impact sender reputation and increase spam complaints.
