The General Data Protection Regulation (GDPR) is a set of rules that govern the way businesses collect, store, and use personal data of EU citizens. When it comes to email marketing, GDPR requires businesses to obtain explicit consent from their subscribers before sending them promotional emails. This means that you can no longer add people to your email list without their permission, and you must provide them with a clear and concise explanation of what they are signing up for. Additionally, GDPR requires businesses to allow subscribers to easily opt-out of receiving emails and to promptly honor those requests. Failure to comply with GDPR can result in hefty fines, so it's important to make sure your email marketing practices are in line with these regulations. Stay compliant and keep your subscribers happy by following these simple rules!
