zendesk spam filter

zendesk-google-apps.js

/*
 * This will let you action on all zendesk emails.
 * Unfortunately this isn't as they arrive, but on a time based schedule.
 * It will help with organisation but not stop realtime notifications from arriving.
 *
 * - Create a new app/script on https://script.google.com.
 * - Setup a time based trigger (1 hour works well for me)
 * - Run the following function: https://gist.github.com/peppy/696d6a9df7036a11fce21252101684df.
 * - IMPORTANT: it currently adds a label which you can then use to filter and manually action on emails.
 *   If you prefer, you can archive or trash automatically (see commented lines at the end of the code),
 *   BUT make sure you understand that this will affect all zendesk emails, including support tickets that
 *   you may genuinely want to read.
