Automated decisions in marketing.

When your segmentation engine decides who gets the airdrop, the bonus, the campaign, it’s automated decision-making with legal effect. Most growth stacks are inside this article without realising.

The rule.

Article 22 restricts solely-automated decisions with legal or similarly significant effects.

Regulation (EU) 2016/679 · Article 22(1)

“The data subject shall have the right not to be subject to a decision based solely on automated processing, including profiling, which produces legal effects concerning him or her or similarly significantly affects him or her.”

The EDPB guidelines (WP251rev.01) read “similarly significant” to cover effects on financial circumstances, access to services, employment, or opportunities. Profiling-based marketing is in scope when the outcome materially affects the consumer.

What it requires.

Identify the decisions. Catalogue every automated decision in the stack: who gets the campaign, the bonus, the airdrop, the dynamic price, the purchase-driving recommendation.

Establish lawful basis. Article 22(2) allows three: contract necessity, EU/Member-State law, or explicit consent. Marketing automation rarely qualifies as contract necessity — that leaves explicit consent.

Transparency. Articles 13(2)(f) and 14(2)(g) require disclosing the existence of automated decision-making, meaningful information about the logic, and the significance and consequences.

Right to human review. Human intervention, the right to express a view, and the right to contest — operationalised, not just a privacy-policy sentence.

Common violations.

Violation pattern · airdrop allocation by score

Airdrop allocation: algorithmic score based on wallet activity, on-chain history, social signals. No disclosure of the scoring logic.

Automated decision with financial effect, no transparency, no human-review path. Fails Article 22 and Article 13(2)(f).

Violation pattern · dynamic pricing by segment

Fee schedule varies by user segment determined algorithmically from KYC data, transaction history, and behavioural signals.

Differential pricing is a financial effect. Fully automated segmentation puts it in Article 22; consent is required.

Violation pattern · lifecycle engine that gates access

Lifecycle automation: users below the engagement-score threshold do not receive the product-launch email; users above do.

The algorithm decides who hears about a financial product. A closer call, but trending toward scope.

How to comply.

Fix 1 · catalogue the decisions

A register: each decision, inputs, outcome, who is affected, lawful basis. Also an Article 30 records-of-processing requirement.

Fix 2 · explicit consent at signup

Collect explicit consent separately from marketing-email consent: “I understand my eligibility for product offerings may be determined by automated processing of my account data, and I consent to this.”

Fix 3 · transparency in privacy notice

Disclose the existence of automated decision-making, the logic in plain language (the factors and how they matter, not the model), and the consequences.

Fix 4 · human-review path

A clear route to request human review — email, support form, in-app — with a documented process and response SLAs.

Fix 5 · DPIA before launching

Run a Data Protection Impact Assessment (Article 35) before any new automated-decision system: risks, mitigations, lawful-basis analysis. Standard in regulated firms; rare in growth stacks.
