You can choose which emails Mindjoy sends you.
Adjusting them
Click your name at the bottom of the sidebar and choose Settings. The settings pages are listed down the left: Account, Profile, Security settings, Email preferences, Accessibility, Agent preferences, Integrations, Classroom Sync and Billing.
Open Email preferences and use the toggles. They cover things like product updates and events, and the digests that tell you what your classes have been doing.
Changes take effect straight away. Emails about your own account, such as a password reset, are always sent.
