Customize Message after CSV subscriber import

When we import subscribers there were messages sent for each user with something like below. How can they be customized?


"Hello John Dow
You have been added as a User to site.org by an Administrator.
This email contains your username and password to log in to site.org
Username: john.doe@mail.com
Password: testettt
Please do not respond to this message as it is automatically generated and is for information purposes only"

Hi

That email message is generated by a Joomla core plugin. If you want to edit the message, please look at the file administrator/language/en-GB.plg_user_joomla.ini, you will see the message and can change it to meet your need
