Send a notification message to the leader.

However, the meaning of the rhetoric should be to make the leaders feel afraid that the leaders will not receive it and worry about delaying the time, so they will repeat the confirmation.

For example, "Confirm that you have received it, please reply after receiving it",

A little more verbose, you can write "in order to ensure that you have received it, please reply for further arrangement" and so on.

Generally speaking, leaders will understand and understand your pain.
