DokDok, a Montreal-based startup, has had an email attachment management application on Google Apps some time. To make this work, it made an API to use internally that intelligently uses email accounts as if they were datastores. Recently, the company announced that this API would be renamed Context.IO and available to all.
LaunchBit, an email ad network, has announced a text ad API. Whether email publishers are blasting status updates, announcements or other news, the LaunchBit API will allow advertisements within the email to make API calls to data relevant to the ad. Monetizing websites with Ads has long been sound practice; however, monetizing emails is somewhat of an untapped market. With easy integration through an API, LaunchBit intends to take advantage of this underdeveloped market.
