To stay GDPR-compliant when using push notifications, you must first get clear permission from each subscriber. This means they should agree to receive messages before you start sending them. Most push services handle this by asking users to click “allow” before being added to your list. You also need to give users the option to unsubscribe easily, either through their browser or in your message settings. Avoid collecting any personal data unless you really need it, and if you do, always be open about how it’s used. It's also a good idea to keep your offers honest and avoid misleading claims. When people trust your messages, they are more likely to keep clicking. Are there any other simple tips others follow to stay compliant?
