When working in Zoho Desk, you may come across the need to perform mass or bulk actions for a ticket. If you want to update lesser number of tickets, then you can choose to perform mass actions. However, when you want to update more than 50 tickets in a list at once, bulk actions are the best option. 

For instance, you're responsible for managing a ticket list, and you're planning to take a vacation next week. To ensure a smooth transition, you need to reassign over 100 tickets to your colleague. While you could increase the number of tickets displayed on a list view to 50 and handle them in smaller groups, Zoho Desk offers a more streamlined solution. With bulk actions you can easily reassign 100 tickets instantly.

Some key benefits of using mass and bulk actions in Zoho Desk

1. Efficiency: Mass and bulk actions are ideal when you need to modify a moderate or large number of records, making it more efficient than manual updates. 
2. Consistency: Mass and bulk actions ensure that all selected records receive the same changes, maintaining data consistency.
3. Streamlined workflow: They allow you to streamline your processes by applying changes to multiple records at once.

Note: Bulk and Mass actions are available only for the Tickets module. 

 Zoho Desk allows you to perform the following bulk and mass actions on tickets.

1. Assign To - Assign multiple tickets to a specific agent or team at once.
2. Update - Make updates or changes to multiple tickets simultaneously.
3. Close - Close several tickets simultaneously, which is particularly useful when handling a large number of resolved issues.
4. Delete - Delete multiple tickets at once, simplifying the process of removing irrelevant or redundant tickets.
   
5. Mark as Spam - Flag multiple tickets as spam to filter out unwanted or irrelevant tickets.
6. Merge - Merge multiple tickets into a single ticket, consolidating related information.
7. Macro - Apply macros to multiple tickets to automate common responses or actions.
8. Revoke Blueprint - Revoke the blueprint from the selected tickets. 
   
9. Update Resolution - Update resolution for multiple tickets at once, which is particularly useful when updating the same issue resolution for multiple tickets. Note that if a ticket already has a resolution and a user attempts to update it via mass action, the existing resolution will be replaced with the new one.
   
   

Notes:

1. It's important to note that even if some of the selected tickets are not associated with a blueprint, the revoke blueprint option will still be available, and it will work on the selected tickets.
2. In the ticket module, when you select all the tickets, you'll see "Bulk Actions." From there, you can choose revoke blueprint to remove blueprint from multiple tickets. It takes a while to revoke the blueprint, you can check the status in the bulk action log. Also the user who initiates the revoke blueprint action is sent an email notification upon completion. 
   
   
   
3. In the ticket detail view, for tickets that have a blueprint applied, you can find the revoke blueprint option under More. Additionally, in the left view, you can see more options icon, which also provide access to the revoke blueprint action.
   
   
   
4. You can search for selected tickets and revoke blueprint only for those tickets.
