As a user, you can choose whether you want to receive email notifications regarding comments, RFCs and versioning.
You can find this setting under your own profile (upper right corner of the application), where there is a a button called Email notifications.

For both comments, RFC’s and versioning, you can choose a notification frequency (daily, weekly, …). The default setting is on ‘weekly digest’.

For comments
You will get a notification when:
- Someone assigns a comment to you / your role / your organisation.
- Someone answers a comment that was created by you.
For RFCs
You will get a notification when:
- Someone mentions you / your role / your organisation in an RFC.
- Someone changes the status of that RFC.
- Someone changes the description of that RFC or of an RFC that was created by you.
For versioning
You will get a notification when:
- Someone creates a static version of a project model you have edit rights to.
- Someone publishes a version of a project model you have published version viewing rights to.
