What should be done to prevent notifications from going to inactive users?

Removing inactive users from the distribution list is essential to preventing notifications from reaching individuals who no longer need or want to receive them. By ensuring that only active users are included in the list, the communication remains relevant and efficient, and it helps to minimize potential confusion or frustration among both active users and the administrators managing notifications.

The other options do not effectively address the issue of inactive users receiving notifications. Changing notification settings for each user might be time-consuming and does not inherently prevent inactive users from being notified. Setting up an automatic filter could help manage incoming notifications but doesn't solve the problem of notifications still being sent to inactive users. Meanwhile, restricting automation to active users only may not be feasible if the system does not automatically differentiate based on user activity statuses without manual intervention. Therefore, the most straightforward and effective approach is to remove inactive users from the distribution list.
