Google has released an updated Gmail API that functionally replaces the Email Settings API. The Gmail API includes a number of new endpoints that enable features previously unavailable through any Google API. Developers have access to filters, auto-replies, send-as aliases, and more.
People and organizations start using Twitter today for general public announcements or as a primary communication channel in closed communities. For example, I use Twitter when I want to share a story with my students or announce a newly available studying material. But what do you do if there are some people who do not want to use Twitter and still rely on email communication? By using Twitter API and Google AppsScript you can write and run a simple mashup that sends an email anytime you post a new message on Twitter.
