This basic Publisher template is a great tool to add to your repertoire. Easily customize-able with your own branding. Enough room for a full page article, a half page article, and a quarter page call out which is just the right size for highlighting a listing.
This template is set up with .125 inch bleeds so the document size is actually 8.75 x 11.25. Don't move any content closer to the edge if you are printing out with bleeds. Check with your print provider first so the mailing section is set up correctly for how you are printing and mailing.
