In setting up your postcard design file, we suggest that you use our free postcard templates with mailing guides. You’ll need the templates to know where the mailing address and postal clear zone will be placed. We have free 7” x 5” postcard templates that can be downloaded in any of these file formats: .jpg/jpeg, .ai, .pdf, .psd, .cdr, and .pub. For more information on our templates, contact our prepress experts through phone or live chat.
