Admin> Edit Language, I found:

{text key='notifications+email_html_bottom'}: Talk soon,<br /> {$site_name}, administration<br /> {$site_url}
{text key='notifications+email_txt_bottom'}: Talk soon,
{$site_name}, administration
{$site_url}

and

{text key='notifications+settings_edit_label'}: Change preferences and frequency of these notifications

{text key='notifications+unsubscribe_all_label'}: Unsubscribe from all notifications

these are correct or not?

Can you describe the problem with more details? Are you saying that link in notification messages is not pointing to a right place?

Yes...Not point to a right link: http://email-notifications/ (wrong link)
Should point to (mysite.com/email-notifications/
