Withdrawal of consent should be as easy as saying yes
DPDP, GDPR, and LGPD all expect withdrawal without detriment. That is a preference-center problem, not a help-desk ticket.
If users must email a DPO to turn off marketing cookies, you do not have lawful consent — you have a maze. Withdrawal must be reachable from the same surfaces where consent was collected.
Propagate immediately
Withdrawal is only real when tags stop, vendors are notified, and downstream caches expire. A consent manager should broadcast the new state to every property that shares the ID space.
Tell the user what happens next: ads may become less relevant, some features may degrade, and required processing continues where a different lawful basis applies.
