The General Data Protection Regulation (GDPR) has had a profound impact on email marketing. It mandates that companies obtain explicit consent from users before sending them marketing emails. This has led to the widespread adoption of double opt-in processes, where users confirm their subscription via a follow-up email.
GDPR has also emphasized the importance of data protection and privacy. Companies are now more cautious about how they collect, store, and use customer data. Compliance with GDPR not only helps avoid legal penalties but also builds trust with your audience.
