What does imessag mean when it is sent as spam?

Sending iMessage as spam means that the domestic Apple system will automatically set such messages as spam.

Because domestic operators do not provide such services, these information are pushed through other means. iMessage means sending information text messages. It is an instant messaging software launched by Apple that can send text messages, Video, etc., which has very high security. Unlike the operator's SMS and MMS services, users only need data support through WiFi or cellular data networks to complete communication.

iMessage spam can be eliminated through settings. After setting, only contacts in the address book will be reminded when they send iMessages, and messages from other unknown IDs will not be reminded.
