Email templates are available in 4me to define the information that the automatically generated email notifications need to contain. To avoid thousands of email notifications from getting sent out accidentally, these templates do not get triggered by imports.
As a further precaution, the email templates are now disabled by default when a new 4me account is created for an organization. That means that no emails get generated until an administrator has completed the setup of the account and has enabled them just before go-live.
The only exception are the two email templates that help users set or reset their 4me password. Those are needed to regain access when the account owner has forgotten this password.
