I'm designing a service for sending out emails for our eCommerce site (order confirmations, alerts etc...) The plan is to have a "SendEmail" method, that generates a chunk of XML representing the email to be sent, and sticks it on an Amazon SQS queue. My web app(s) and other applications will use this to "send" emails.

I then require a way of checking the queue, and physically sending out the email messages. (I know how I'm going to be dispatching emails)

I'm curious as to what the best way to "poll" the queue would be?

Should I create a windows service, and use something like Quartz.net to schedule it to check the queue every x number of minutes for example? Is there a better way of doing this?
