# Help: Mail Users

#### Description

XOOPS has a built in messaging system that enables you to send a message to your entire registered user base or subgroups thereof, or using date filters. This can be in the form of a private message (i.e. through the XOOPS built-in messaging system) or through an email. A range of options is available for filtering out subgroups of users from your membership.
You can also use predefined tags that will enable you to personalize your message.
