Feature access
To control which features are visible or accessible, they can be configured in the "Roles" page. Go to Settings > Roles. Here, you can assign or restrict access based on specific roles to ensure that only authorized users can view or interact with certain features on the broadcast page.
The features (add A/B split, dynamic insertion, tag metadata, link shortener, add coupon) highlighted in the screen below will not be visible if you do not have the required access permissions. These features will be shown or hidden based on the respective permissions assigned to each user.
Manage Subscribers (applicable only for list)
When you're working on the broadcast screen and sending a broadcast, you will have access to the Manage Subscribers button.
This button needs to be enabled through Manage Subscribers option under role-based permissions.
When you click the Manage Subscribers button, a modal will open, allowing you to add subscribers. In this modal, you can search for subscribers by entering their first or last name in the search box. Once you initiate the search, matching subscribers will appear in the dropdown list. The search uses an exact match, so if you search for "Lee," it will display all variations such as Lee/lee/LEE.
You can also search for subscribers using partial terms. When you enter any part of a subscriber's name into the search box and click 
Search, the relevant results will be displayed that match your input.
After selecting a subscriber, click Add to include them in the list, and the table below will update to show the subscriber's name, number, and list name.
Exclude is available beside each subscriber in the Subscribers table. Clicking Exclude will remove the subscriber from the current broadcast, grey out their entry, and change the icon to 
Add. If you decide to re-add the subscriber, click Add, and they will be restored to the broadcast. The added subscriber will be added to the Added Subscribers list.
The number of subscribers in the list is dynamically updated each time a subscriber is added or removed. This ensures that the subscriber count always reflects the most current status of your broadcast list.
When you add any adhoc subscribers, the count will be displayed on the broadcast screen. Similarly, if you remove an adhoc added subscriber, the count will update accordingly.
For example, if there is a subscriber (X) already added in the “Added Subscribers” table and a user adds a new list in which this subscriber (X) is present, then the subscriber(X) moves to the main “Subscribers” table. The count will adjust based on the remaining subscribers in the "Added Subscribers" list.
When you exclude a subscriber from the "Subscribers" table, the updated count will be visible on the broadcast screen. If you remove a list that already contains an excluded subscriber, then all subscribers in that list, including the excluded ones, will be removed from the "Subscribers" table. The count will update accordingly.
In the Added Subscriber table, 
Delete is available for each subscriber. Clicking Delete will remove the subscriber from the broadcast.
The search functionality allows you to find users by entering either their name or phone number. You can also search for subscribers using partial terms. When you enter any part of a subscriber's name into the search box and click Search, the relevant results will be displayed that match your input.
When you're working with a broadcast and you add or remove a subscriber using the Manage Subscribers button, the updated count of added or excluded subscribers will be visible next to the Manage Subscribers button. This ensures you can easily track the number of subscribers as you make changes.
The added and excluded subscribers are also displayed in the Recipients column of the broadcast Scheduled tab.
