What is iMessage Detection
iMessage detection verifies whether a phone number is likely reachable through Apple's iMessage channel before your team chooses a delivery route.
Routing context
Use the result as a pre-campaign signal, not as a message-sending product by itself.
Privacy-aware verification
Run list hygiene and channel planning without sending a visible message to the verified number.
Why It Matters for US Marketing
In the US, many customers are used to Apple Messages as their daily texting experience. Detecting iMessage availability helps teams plan routing before sending.
