Hi,
this email is managed by Joomla (not Easy Profile).

Try to check if it is enabled:
- Go to Users->Manage->Options
- Check if "Send Mail to Administrators" option is enabled

Try to check if email works:
- Go to System->Global Configuration
- Go to "Server" tab
- Click to button "Send Test Mail"

Also check in SPAM folder, maybe it already is enabled and works.

Did al this and test-mail comes in fine. But from Easy Profile nothing. Als not in SPAM.

Do you have any other suggestion?

Thank you

Do you create user from frontend?

Do you have any other suggestion?

Try to check that your user is enabled for reception of these mail from Users->>Manage->Choose your account->Account Details tab->Receive System Emails

But from Easy Profile nothing

Easy Profile extends Joomla user management (not replace), so the registration form is the same of Joomla with many improvements (Javascript and User plugins). So with or without Easy Profile then you will have same behavior about email.
