Email Subscription is the setting that controls whether you receive member credit emails from the platform.
If your email subscription is active, you can receive credit emails from other members and earn credits by reading them and clicking the credit links.
If you unsubscribe, you will no longer receive member credit emails, which means you may not be able to earn email credits through reading those emails.
You can manage this option from your account depending on whether you want to receive promotional credit emails or not.
