In UXPressia, you can set up two types of email notifications: project and workspace-related notifications and notifications about comments and mentions in maps and personas.
How to set them up
To receive only those notifications that are important to you, go to email notification settings in your profile.
Managing comment notifications from a map/persona page
You can also turn off email notifications about comments for a specific map or persona.
To disable notifications for all maps and personas, go to your profile settings.
