Your individual inbox uses the following tabs to filter conversations:

• Open: Conversations that are not archived or snoozed and need action.
• Archived: Conversations you have archived.
• Snoozed: Conversations you have snoozed for follow-up later.
• Trash: Conversations you have trashed from the Me section in your sidebar.
• Spam: Conversations your email provider has marked as spam or that you have marked as spam in Front.

All of these tabs can be found on the upper right next to the "Compose" button when you are looking at your Individual Inbox.

These are the default tabs for your shared inboxes:

• Unassigned: Conversations that have not been assigned to a teammate and still open.
• Assigned: Conversations that are assigned to a teammate and still open.
• Archived: Conversations that someone archives in the shared inbox.
• Snoozed: Conversations that someone snoozes in the shared inbox.
• Trash: Conversations that someone has trashed in the shared inbox. 
• Spam: Conversations your email provider has marked as spam or that someone has marked as spam in the shared inbox in Front.

All of these tabs can be found on the upper right next to the "Compose" button when you are looking at a Shared Inbox.
