I host a service tool to contact our suppliers in case of a defect. Every 20 minutes the tool checks if there are new processes and if so suppliers are contacted per mail with a link to a form that contains questions and relevant files. Newbie mistake of me was to send the mail and set a database entry that the supplier had been contacted. In exact that order. You can guess which part failed at some point and who got the same mail every 20 minutes... They did respond with above average speed though. Didn't stop the mails of course.
