recipient deduplication

The recipient deduplication tag on WindowsForum.com follows discussion of Microsoft's planned deduplication support for SMS and custom channels in Dynamics 365 Customer Insights – Journeys. The tagged thread covers roadmap item 579903, which describes sending a message only once to each phone number or custom-channel address per send, so multiple customer records sharing the same destination do not trigger repeated deliveries. The roadmap lists the feature as in development, with general availability targeted for December 2026 in Worldwide (Standard Multi-Tenant) environments. Coverage is currently limited to this planned release rather than hands-on configuration guidance.
