i'm looking for a GUI for Amazon Simple Email Service, which displays stats of sent mails. Does someone know any?
The Amazon SES Management Console is a simple and intuitive web-based user interface for Amazon SES that allows you to do common SES management functions with a few clicks of your mouse. These include checking your sending quota and usage; seeing your Amazon SES bounce, complaint, and rejection metrics over time; verifying sender email addresses; and sending both formatted and raw test emails. [emphasis mine]
