Printed Postage Impression (PPI) download

Calling all direct mail nuts: download your own [PPI] design from Royal Mail's website, personalised with your PPI licence number. Choose between First Class, Second Class and Mailsort 3, and between English and Welsh PPIs, as JPG or TIFF.

You're right, what has traditional direct mail got to do with e-marketing? (Useful to see if your agency is printing the right PPI on the next mailer that is driving traffic to your website though.)
