Email is in our DNA. For over 25 years Openwave’s Email Platform has been providing scalable, secure and highly performant email software for Communication Service Providers increasing subscriber retention and enabling monetization opportunities.


Mastering Email Services for
Enhanced Subscriber Retention

Operating an email platform is a very difficult business, one which requires the right partner and platform. Email continues to be a key application in helping Communication Service Providers to reduce overall subscriber churn. Email addresses have become a de facto ubiquitous identity and are key for engaging with online services. Subscribers understand the value of retaining this unique digital identity, whereby many service providers now charge orphan users (email users that are not customers anymore) successfully.

Building, delivering and managing email for service providers is what Openwave has been doing since its inception. We have been supporting customers as they evolve their email and messaging offerings, helping manage their costs, protect against personnel changes and supporting revenue generation initiatives.
