Whether you make a separate app for the contacts or leave it as it is, that the contacts are in the mail app, is a matter of taste.
What would be more important is that the contacts that you enter there are then also available as contacts in the phone, e.g. when you use the phone app.
I would also find it practical if the appointments that you enter under contacts (e.g. birthdays) are then also automatically entered into the calendar.
