Email notifications are automated messages sent to a user's email address to inform them about specific events or updates. These notifications can be triggered by various actions, such as receiving a new message, a calendar event, or changes in account settings. They help users stay informed without needing to constantly check their accounts. Many online services, including social media platforms and e-commerce websites, utilize email notifications to enhance user engagement. Users can often customize their notification preferences, choosing which types of alerts they want to receive and how frequently they want to be notified. This customization helps users manage their inbox effectively.
