As companies flood EU residents' inboxes ahead of GDPR rollout, experts say many of those consent emails are unnecessary and some may be even illegal
Context & Ripple Effects
The May 2018 GDPR deadline triggered a mass re-permissioning exercise: companies emailed their entire EU mailing lists to obtain fresh consent before the law took effect. The Guardian's Alex Hern reports that experts consider many of these emails legally unnecessary — consent was only required where the lawful basis for processing had actually changed — and that some cross into illegality.
The confusion was predictable. Weeks later, experts were still warning that GDPR's vagueness meant publishers may be breaking the law while trying to comply, and email marketing firms were already bracing to lose most of their lists as users ignored re-consent requests.
First-order effects
- EU residents' inboxes are flooded with consent requests, many from senders who never needed to ask — legitimate marketers pay a deliverability and trust cost alongside the genuinely non-compliant ones.
- Senders who misjudge whether consent was required expose themselves to the very enforcement action GDPR was meant to trigger, since an unnecessary or coercive request can itself be unlawful processing.
Second-order effects
- Email marketing firms report they cannot get most people on mailing lists to respond at all, with some expecting to lose around 80% of their lists — shrinking the addressable audience and pushing pricing toward verified, engaged contacts.
- The same ambiguity that produced bad consent emails soon showed up on the web: by 2020, research found most cookie banners still violated informed-consent rules through pre-ticked boxes and hidden reject options (TechCrunch study).
Third-order effects
- Consent becomes a design discipline rather than a checkbox: firms that treat permission requests as UX and legal architecture together gain durable advantage over those that blast lists at deadlines.
- Rather than deterring imitation, the messy rollout became an export — EU officials began tying data protection to trade deals to encourage countries like Brazil, Japan, and South Korea to adopt similar laws (New York Times), spreading both the standard and its compliance confusions.
The trend: GDPR's rollout turned user consent into a global compliance industry, where the gap between what the law requires and how companies implement it keeps generating both enforcement risk and exportable regulation.
