User consent is crucial when using push notification traffic to promote affiliate offers. It ensures compliance with privacy laws like GDPR and CAN-SPAM, protecting both the user and the advertiser. Gaining consent builds trust, leading to higher engagement and lower unsubscribe rates. Without consent, push notifications can be perceived as intrusive or spammy, damaging brand reputation and risking legal penalties. Ethical marketing practices that prioritize user choice improve long-term success by fostering a loyal audience. Consent also allows for more targeted messaging, increasing conversion rates and affiliate revenue. In a digital landscape where privacy concerns are rising, transparent opt-in mechanisms are not just a legal requirement but a strategic advantage in affiliate marketing.
