You can archive the message threads to hide them from the main inbox.
In order to archive, select the thread and click on the appropriate button in the actions bar. The thread will move from the inbox view to the archived view. Moving it back to the inbox is done the same way.
Threads will automatically move from archived to inbox if the guest sends a message, but not if the host sends one. Threads cannot be both archived and snoozed at the same time.
How to bulk archive messages
To bulk archive messages, you will just need to go to Inbox > Bulk Update
Click the dropdown for "Mark message thread as"and select Archived. Below you may select the date that you prefer to decide which messages the system will archive for you.
