Is there a limit on how many emails you can send through this? Edit: I should add that I use Google Scripts to automate a lot of responses to frequent support emails I get. These are really well categorized so that if the program doesn't understand what the user wants, it goes to another folder where I personally review it. Works great so far but working with Python I may be able to build something more powerful.
