Hi there,
Please allow me to edit / and update the theme so it won't break when updated. Secondly, for that email I have to study what sort of email you are talking about, weather thats being sent by your email server if thats the case we'll have control over this, if not then how can that be stopped I can't commit to fix that unless I am fully sure what that is.
Lets discuss this more and get it done. and yes lastly, I would need admin and ftp access to fix the site for updation
Regards,
- Syed
