For instructions, see [Create New Message Category](/v1/docs/create-new-message-category). ## Assigning Message Categories​ The category is assigned to a message before the message sendout in the [​Configuration for Sendout](/v1/docs/configuration-for-sendout) in the Advanced Options area. For instructions, see [Create New Message Category](/v1/docs/create-new-message-category). Only one category can be assigned to a message at any time. After a message has been sent, it is no longer possible to change the category of the message. ## Filtering by Message Category ​ You can now filter by message category in **Message Statistics**. For more information, see [Message Category Filter](/v1/docs/mapp-engage-message-category-filter).
