Dear Parchita,
For your kind information, a purchase code/license is for only using one active domain/sub-domain/directory/sub-directory. To activate the theme on a new domain/sub-domain/directory/sub-directory, you need to deactivate the purchase code/license from the existing domain/sub-domain/directory/sub-directory where it installed now or you could buy another license to use the theme separately in a separate domain/sub-domain/directory/sub-directory.
Moreover, if the emails arrive with a delay to the client then it’s all about your mail server issue. In this case, you could contact your hosting provider.
Furthermore, the email template/format we have used it’s a standard format for all with all required information of an order. If you are looking for something different based on your needs and requirements then you could contact there https://www.themelooks.com/contact/ with your requirements with details to get a quote for the customization service.
Best Regards,
ThemeLooks Support Team
