This is a Ruby library created for wrapping the Gmail API. This unofficial library provides access to all essential Gmail functionality like: searching, archive, delete, read/unread flagging, and reading and sending emails. Hosted on GitHub, the library documentation includes installation instructions as well as extensive code examples.
ZeroBounce upgrades its global data center infrastructure by deploying high-availability clusters in the United States. The new data center responds to the growing demand for real-time email verification and is intended to better serve U.S. customers through the API.
A little less than a year after launching a private beta of the UK government's notification platform, GDS has upgraded to v2 of the associated API. GOV.UK Notify is a service that allows the government to text, email, and send letters to citizens and track the progress of such notifications.
Additional third party integration with Gmail has been possible (you only have to look at all the contact import features from sites like Facebook), but these have either been clunky manual procedures that involve exporting contacts to a CVS file, or they require you to supply your email password. Neither option is all that attractive. Now there is an alternative. Google have recently added the ability to access the IMAP/SMTP features of particular Gmail account using OAuth.
