Mail drafted for employees who have not informed about their client visit

Dear All, Need advice on the below mail drafted for employees who have not informed about their client visit.

Dear Team,

We request you all to plan and inform about your leaves well in advance to your supervisor/HOD keeping HR in copy.
While we encourage you to go on a client meeting, at the same time we expect you to update us about your client visit and/or going out for any office-related work.
It is advisable that you come to the office, mark your attendance (in-time in the machine) and go for a client visit and same in the evening.
If you are unable to come to the office Kindly inform your immediate supervisor/ HOD one day (i.e. one working day) prior about your visit and you can write it to me

You are hereby requested to extend your kind cooperation..

Regards,

The contents are ok. Also suggest, you may add a line cautioning any one not complying with are warned with appropriate action including stoppage of increment for defaulters and so on. Also required to submit a monthly report containing all such client visits, follow up action taken etc.on or before 5th of every month to the HODs c.c.to HR.
