What happens when you Block an Email?

When you block an email, you prevent further communication from that specific sender. Their emails will no longer reach your inbox, automatically redirecting to a designated spam or blocked folder.

This action is commonly taken to filter out unwanted or harassing messages, ensuring a cleaner inbox and reducing potential security risks associated with malicious content.

💡 Keep in mind that while blocking stops their emails, it doesn’t guarantee an end to all contact, as the sender might use alternative means if available.
