I have find the solution i made a mistake in my config.xml file.

We have to define the mail template like this

<template>
    <email>
        <{section_name}_{group_name}_{fields_name} translate="label" module="mymodule">
        <label>Custom Email Template</label>
        <file>mymodule/custom_email.html</file>
        <type>html</type>
        </{section_name}_{group_name}_{fields_name}>
    </email>
</template>

{section_name} {group_name} {fields_name} in system.xml file.

Cheers
