EmailSubject: Re: Idea for [Product]: [feature]
Hi [Customer name],
Thanks for taking the time to write this up. Being able to [feature, in their words] would clearly save you [the benefit they described].
I've added your request to our product board along with your use case. We look at these when planning, and the number of customers asking for something does move it up the list.
I can't give you a date, but I've linked your account to the request, so you'll hear from me directly if we build it.
