Predelivery Logic: more than “just” a policy engine

Keeping your unpredictable email communication channel under control has become an increasingly difficult task, not just in terms of efficient routing within complex company networks. Addressing challenges like process automation goes beyond what a standard solution can provide.
The feedback from our large enterprise customers is clear: to tackle new complexities, an intelligent and flexible approach is needed, especially when email communication moves to the cloud. Companies want more control over their incoming email traffic, ideally before emails are delivered to their internal infrastructure.

Retarus’ Predelivery Logic is our answer. This new service analyzes and optimizes emails based on client’s rules during their interaction with the Retarus Enterprise Cloud before they are forwarded to the client’s infrastructure. The result is maximum flexibility and nearly limitless combinations of options for implementation.

Predelivery Logic is offered as a self-service solution via the Retarus Enterprise Administration Services (EAS) Portal. You can create, edit, and prioritize rules in the portal’s editor at any time, all with full transparency. Retarus experts are always available upon request to consult with you about best practices for implementing rules.

Retarus Email Continuity Service

Extensive usage options

Retarus’ Predelivery Logic goes far beyond the functionality of typical policy engines available in the market. Our solution offers user-dependent email routing to specific servers/locations within the company network or to subsidiaries, but goes an important step further: Predelivery Logic significantly supports the automation of critical business processes.
As an example, emails can be processed based on their content or language including their automated presorting into role-based inboxes. When an email arrives, it is routed—depending on its language or content—to the applicable servers or even directly to the responsible department within a company. Fully automated, rule-based processing of emails is also available—from rewriting addresses to adding key words (“tags”) to subject lines.
