+ 1 for making the scheduling indefinite or until stopped. 
+ 1 for having the ability to customise the email subject and text. 

Also I don't recognise anyone discussing this but based on testing, the email delivery sends all data and ignores the receiving user's data restrictions. Please make it so it either recognises the user's restrictions when deciding what data to email or allow me to setup individual scheduled deliveries for each data set.
