Email of Tasks

Email of Tasks

I have just started using Zoho and it looks helpful. But i have an issue with tasks.
When i create one i instantly receive an emain about that taks, even if i set the due date in the future.

What i want is to receive a mail not now, but at a specific time in the future, so i dont forget the task.
There is no point in receiving now each email for each new task.

My question is how can i set a specific so i receive a message at that time in the future.

Thanks in advance :)
