Flocknote's aim is to make the bulk emailing process a simple one. The service was originally created as a tool for churches, ministries and other organisations that had the need to communicate quickly and effectively with their members. The result is an easy-to-use email and text messaging service that gets the job done without the glitches involved in some more complicated systems. Flocknote also provides The Flocknote API that makes his functionality available to third party developers who may want to integrate it with other applications.
Clickatell, a leading mobile messaging and global communications solutions provider, has just announced the launch of the new Connect API allowing developers to integrate into their web and mobile applications in-app Short Message Service (SMS) functionality.
