RM579903Dynamics 365 Customer Insights - Journeys: Send each message only once with deduplication for SMS and custom channels

Deduplicates recipients by contact point, so each phone number or custom channel address gets the message once per send.

Eliminates manual post-send clean-up, wasted messaging spend and the customer annoyance of duplicate texts.

Brings SMS and custom channels to parity with email's built-in deduplication.
