Which configuration is necessary for sending an automatic rejection letter and email?

To successfully send an automatic rejection letter and email within Pega's framework, it is essential to use the CorrNew utility in the rejection flow. This utility is specifically designed to manage correspondence in Pega applications. By incorporating CorrNew, you can automate the generation and dispatch of letters and emails based on specific triggers in your case management process.

This automation enables consistent communication and helps ensure that users receive timely notifications regarding case outcomes without necessitating manual intervention. The ability to automatically generate correspondence not only enhances user satisfaction but also improves operational efficiency by reducing the workload on staff who might otherwise need to handle such communications manually.

The other configurations mentioned may not provide the necessary capability for automated correspondence. A manual process is inherently less efficient, a flow action alone may not encompass the specifics of generating correspondence, and integrating with external systems, while useful for broader communication needs, doesn't directly address the internal capabilities Pega provides for handling correspondence effectively within its own ecosystem.
