# Contact Users
A Project's Contact Users page gives Project Administrators the ability to communicate with the users of their project based off a variety of different filters.
This feature will only be enabled if the necessary email configuration properties have been set for this instance of SkillTree
Up to 15 different filters can be combined to target users of your project based on the achievement of levels across the Project/Subjects as well as the achievement specific Badges and Skills or the lack of achievement of specific Skills.
Once a Project Administrator has selected the desired filters, they can create an email that can be sent to the selected users. The
specified email can also be previewed using the
Preview button. This will send the specified email to the currently authenticated
user so that formatting, content, and display can be validated.
The email body supports markdown
