Lawful Bases for Processing Leads: Consent vs. Legitimate Interest

[nusaibatara]

Core GDPR Principles for Lead Generation
Successful GDPR-compliant lead generation is built upon several foundational principles:

Lawfulness, Fairness, and Transparency: Data must be processed lawfully, fairly, and in a transparent manner. This means being upfront with individuals about what data brazil phone number list you collect, why, and how you will use it.
Purpose Limitation: Data should be collected for specified, explicit, and legitimate purposes and not further processed in a manner incompatible with those purposes. You can't collect data for lead generation and then use it for an entirely different, undisclosed purpose.
Data Minimization: Only collect personal data that is adequate, relevant, and limited to what is necessary for the purposes for which it is processed. Don't ask for a full address if you only need an email for a newsletter.
Accuracy: Personal data must be accurate and, where necessary, kept up to date. Incorrect lead data is not only non-compliant but also ineffective.
Storage Limitation: Personal data should be kept in a form which permits identification of data subjects for no longer than is necessary for the purposes for which the personal data are processed.
Integrity and Confidentiality (Security): Personal data must be processed in a manner that ensures appropriate security of the personal data, including protection against unauthorized or unlawful processing and against accidental loss, destruction, or damage, using appropriate technical or organizational measures.
Accountability: The data controller (your business) is responsible for, and must be able to demonstrate compliance with, the above principles.

One of the most critical aspects of GDPR for lead generation is establishing a lawful basis for processing personal data. The two most common bases are Consent and Legitimate Interest:

1. Consent (Primarily for B2C Lead Generation)
